jQuery custom content scroller

jQuery custom content scroller

Highly customizable custom scrollbar jQuery plugin. Features include vertical and/or horizontal scrollbar(s), adjustable scrolling momentum, mouse-wheel (via jQuery mousewheel plugin), keyboard and touch support, ready-to-use themes and customization via CSS, RTL direction support, option parameters for full control of scrollbar functionality, methods for triggering actions like scroll-to, update, destroy etc., user-defined callbacks and more.

Current version 3.0.5 (Changelog)

Upgrading version 2.x to 3.x

When upgrading from version 2.x to 3.x it’s important to use version 3 CSS and .png files. Version 3 is backwards compatible but it’s also a huge overhaul. One significant change is that you don’t need to call the update method manually (the script does it automatically). For more info see changelog.

Version 2.x is still maintained and updated here.

How to use it

Get started by downloading the archive which contains the plugin files (and a pretty large amount of HTML examples and demos). Extract and upload jquery.mCustomScrollbar.concat.min.js, jquery.mCustomScrollbar.css and mCSB_buttons.png to your web server.

Include jquery.mCustomScrollbar.css in the head tag your html document

<link rel="stylesheet" href="jquery.mCustomScrollbar.css" />

Include jQuery library (if your project doesn’t use it already) and jquery.mCustomScrollbar.concat.min.js in the head tag or at the very bottom of your document, just before the closing body tag (usually recommended for better performance)

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="jquery.mCustomScrollbar.concat.min.js"></script>

After files inclusion, add the class mCustomScrollbar to any element you want to add custom scrollbar(s)

Alternatively, call mCustomScrollbar function on the element selector you want to add the scrollbar(s)

<script>
    (function($){
        $(window).load(function(){
            $(".content").mCustomScrollbar();
        });
    })(jQuery);
</script>

The example above adds scrollbars to elements with class name content

In order for the scrollbar to appear, the element(s) should have the typical CSS properties of an overflowed block which are a height (or max-height) value, an overflow value of auto (or hidden) and content long enough to require scrolling.

By default the script applies the vertical scrollbar. To add a horizontal or 2-axis scrollbars, invoke mCustomScrollbar function with the axis option set to “x” or “yx” respectively

$(".content").mCustomScrollbar({
    axis:"x" // horizontal scrollbar
});
$(".content").mCustomScrollbar({
    axis:"yx" // vertical and horizontal scrollbar
});

To change the appearance of the scrollbar, set the theme option parameter to any of the ready-to-use themes available in jquery.mCustomScrollbar.css

$(".content").mCustomScrollbar({
    theme:"dark"
});

Loading scripts from Github

Instead of hosting the plugin files on your web server, you can load each one directly from Github. You can choose to always load the latest plugin version or a specific one

<!-- latest -->
<link rel="stylesheet" href="http://malihu.github.io/custom-scrollbar/jquery.mCustomScrollbar.min.css" />
<script src="http://malihu.github.io/custom-scrollbar/jquery.mCustomScrollbar.concat.min.js"></script>
<!-- v3.0.0 -->
<link rel="stylesheet" href="http://malihu.github.io/custom-scrollbar/3.0.0/jquery.mCustomScrollbar.min.css" />
<script src="http://malihu.github.io/custom-scrollbar/3.0.0/jquery.mCustomScrollbar.concat.min.js"></script>

Plugin files in detail

jquery.mCustomScrollbar.css contains the basic styling of the custom scrollbar and the ready-to-use themes. It should normally be included in the head tag of your html (typically before any script tags). If you wish to reduce http requests and/or have all your website stylesheet in a single file, you should move scrollbars styling in your main CSS document.

mCSB_buttons.png contains all the button arrows (up, down, left and right) as image sprites for all scrollbar themes. The plugin archive contains the PSD source (source-files/mCSB_buttons.psd) so you can change them or add your own.

jquery.mCustomScrollbar.concat.min.js is the main plugin file which contains the custom scrollbar script as well as dependencies (e.g. jQuery mousewheel plugin), concatenated and minified. This file should be included after jQuery library inclusion.

mCustomScrollbar function

Call mCustomScrollbar function after jQuery and jquery.mCustomScrollbar.concat.min.js script tags. The HTML should look something like this:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="jquery.mCustomScrollbar.concat.min.js"></script>
<script>
    (function($){
        $(window).load(function(){
            $(".content").mCustomScrollbar();
        });
    })(jQuery);
</script>

The code is wrapped in (function($){ ... })(jQuery);. This ensures no conflict between jQuery and other libraries using $ shortcut (see Using jQuery with Other Libraries for more info). The plugin function is called on window load ($(window).load()) so it executes after all page elements are fully loaded. To call mCustomScrollbar on document ready (code executes when the DOM is ready)

<script>
    (function($){
        $(document).ready(function(){
            $(".content").mCustomScrollbar();
        });
    })(jQuery);
</script>

You can change the function selector (".content") to anything you want (an element id, class name, js variable etc.) – see CSS selectors. For instance, if you want custom scrollbars to apply on the element with id content-1, you simply do:

$("#content-1").mCustomScrollbar();

You may also have multiple selectors by inserting comma separated values

$(".content,#content-1").mCustomScrollbar();

The above code adds custom scrollbars to a)every element with class name content and b)the element with id content-1.

Additionally, you may want to call mCustomScrollbar multiple times within a page in order to set different options (configuration and option parameters explained below) for each selector

<script>
  (function($){
    $(window).load(function(){
      $("#vertical-content").mCustomScrollbar({
        theme:"light-3",
        scrollButtons:{
          enable:true
        }
      });
      $("#horizontal-content").mCustomScrollbar({
        axis:"x",
        theme:"3d"
      });
    });
  })(jQuery);
</script>

Configuration

mCustomScrollbar function option parameters

setWidth: false
Set the width of your content (overwrites CSS width), value in pixels (integer) or percentage (string).
setHeight: false
Set the height of your content (overwrites CSS height), value in pixels (integer) or percentage (string).
setTop: 0
Set the initial css top property of content, accepts string values (css top position). Usage example: setTop: "-100px".
setLeft: 0
Set the initial css left property of content, accepts string values (css left position). Usage example: setLeft: "-100px".
axis: string
Define content’s scrolling axis (the type of scrollbars added to the element). There are 3 available values: “y”, “x” and “yx”. Set axis: "y" (default) for vertical scrollbar and axis: "x" for horizontal scrollbar. By setting axis: "yx", both vertical and horizontal scrollbars will be applied if necessary.
scrollbarPosition: string
Set the position of scrollbar relative to content. There are 2 available values: “inside” and “outside”. Setting scrollbarPosition: "inside" (default) makes scrollbar appear inside the scrolling area. Setting scrollbarPosition: "outside" makes scrollbar appear out of the scrolling area. Note that setting the value to “outside” requires your element (or parent elements) to have CSS position: relative (otherwise the scrollbar will be positioned in relation to the whole page).
scrollInertia: integer
Set the amount of scrolling momentum as duration in milliseconds. Higher value means longer scrolling momentum which translates to smoother/more progressive scrolling animation stopping. Set to 0 to disable.
autoDraggerLength: boolean
Enable or disable auto-adjusting scrollbar(s) dragger length in relation to scrolling amount (same bahavior with browser’s native scrollbar). Set autoDraggerLength: false when you want your scrollbar to have a fixed size (e.g. a cycle).
autoHideScrollbar: boolean
Enable or disable auto-hiding the scrollbar(s). Setting autoHideScrollbar: true will hide the scrollbar(s) when scrolling is idle and/or cursor is out of the scrolling area.
autoExpandScrollbar: boolean
Enable or disable auto-expanding the scrollbar(s) when cursor is over or dragging the scrollbar.
alwaysShowScrollbar: integer
Always keep scrollbar(s) visible, even when there’s nothing to scroll. Set alwaysShowScrollbar: 1 to keep only dragger rail visible and alwaysShowScrollbar: 2 to keep all scrollbar components (dragger, rail, buttons etc.) visible. Set to 0 (default) to disable.
snapAmount: integer
Make scrolling snap to a multiple of a fixed number of pixels. Useful in cases like scrolling tabular data, image thumbnails or slides and you need to prevent scrolling from stopping half-way your table rows, images, slides etc. Note that your elements must be of equal width or height in order for this to work properly.
snapOffset: integer
Set an offset (in pixels) for the snapAmount option. Useful when for example you need to offset the snap amount of table rows by the table title.
mouseWheel:{ enable: boolean }
Enable or disable content scrolling via mouse-wheel.
mouseWheel:{ scrollAmount: integer }
Set the mouse-wheel scrolling amount (in pixels). The default value “auto” adjusts scrolling amount according to scrollable content length.
mouseWheel:{ axis: string }
Define the mouse-wheel scrolling axis when both vertical and horizontal scrollbars are present. Set axis: "y" (default) for vertical or axis: "x" for horizontal scrolling.
mouseWheel:{ preventDefault: boolean }
Prevent the default behaviour which automatically scrolls the parent element when end or beginning of scrolling is reached (same bahavior with browser’s native scrollbar).
mouseWheel:{ deltaFactor: integer }
Set the number of pixels one wheel notch scrolls. The default value “auto” uses the OS/browser value.
mouseWheel:{ normalizeDelta: boolean }
Enable or disable mouse-wheel acceleration. Setting normalizeDelta: true translates mouse-wheel delta value to -1 or 1.
mouseWheel:{ invert: boolean }
Invert mouse-wheel scrolling direction. Set to true to scroll down or right when mouse-wheel is turned upwards.
mouseWheel:{ disableOver: array }
Set the tags that disable mouse-wheel when cursor is over them. Default value is ["select","option","keygen","datalist","textarea"]
scrollButtons:{ enable: boolean }
Enable or disable scrollbar buttons.
scrollButtons:{ scrollAmount: integer }
Set the buttons scrolling amount (in pixels). The default value “auto” adjusts scrolling amount according to scrollable content length.
scrollButtons:{ scrollType: string }
Define the buttons scrolling type/behavior. There are 2 available values: “stepless” and “stepped”. Setting scrollType: "stepless" (default) means that holding/pressing the button will continuously scroll the content. Setting scrollType: "stepped" means that each button click will scroll content a certain amount (defined in scrollAmount option above).
keyboard:{ enable: boolean }
Enable or disable content scrolling via the keyboard. The plugin supports the directional arrows (top, left, right and down), page-up (PgUp), page-down (PgDn), Home and End keys.
keyboard:{ scrollAmount: integer }
Set the keyboard arrows scrolling amount (in pixels). The default value “auto” adjusts scrolling amount according to scrollable content length.
keyboard:{ scrollType: string }
Define the keyboard arrows scrolling type/behavior. There are 2 available values: “stepless” and “stepped”. Setting scrollType: "stepless" (default) means that pressing the arrow key will continuously scroll the content. Setting scrollType: "stepped" means that each key release will scroll content a certain amount (defined in scrollAmount option above).
contentTouchScroll: integer
Enable or disable content touch-swipe scrolling for touch-enabled devices. To completely disable, set contentTouchScroll: false. Integer values define the axis-specific minimum amount required for scrolling momentum (default value is 25).
advanced:{ autoExpandHorizontalScroll: boolean }
Auto-expand content horizontally (for “x” or “yx” axis). If set to true, content will expand horizontally to accomodate any floated/inline-block elements.
advanced:{ autoScrollOnFocus: string }
Set the list of elements that will auto-scroll content to their position when focused. For example, when pressing TAB key to focus input fields, if the field is out of the viewable area the content will scroll to its top/left position (same bahavior with browser’s native scrollbar). To completely disable this functionality, set autoScrollOnFocus: false. Default value is "input,textarea,select,button,datalist,keygen,a[tabindex],area,object,[contenteditable='true']"
advanced:{ updateOnContentResize: boolean }
Update scrollbar(s) automatically on content, element or viewport resize. The value should be true (default) for fluid layouts/elements, adding/removing content dynamically, hiding/showing elements etc.
advanced:{ updateOnImageLoad: boolean }
Update scrollbar(s) automatically each time an image inside the element is fully loaded. The value should be true (default) when your content contains images.
advanced:{ updateOnSelectorChange: string }
Update scrollbar(s) automatically when the amount and size of specific selectors changes. Useful when you need to update the scrollbar(s) automatically, each time a type of element is added, removed or changes its size. For example, setting updateOnSelectorChange: "ul li" will update scrollbars each time list-items inside the element are changed. Setting the value to true, will update scrollbars each time any element is changed. To disable (default) set to false.
advanced:{ releaseDraggableSelectors: string }
Add extra selector(s) that’ll release scrollbar dragging upon mouseup, pointerup, touchend etc. (e.g. releaseDraggableSelectors: ".myClass, #myID").

    console.log("scrolled to end of content.");
  }
}
Set to false (default) to disable.
callbacks:{
    onTotalScrollBack: function(){}
}
A function (or custom code) to call when scrolling is completed and content is scrolled back to the beginning (top/left) (callbacks demo). Example:
callbacks:{
  onTotalScrollBack:function(){
    console.log("scrolled back to the beginning of content.");
  }
}
Set to false (default) to disable.
callbacks:{
    onTotalScrollOffset: Integer
}
Set an offset for the onTotalScroll option. For example, setting onTotalScrollOffset: 100 will trigger the onTotalScroll callback 100 pixels before the end of scrolling is reached.
callbacks:{
    onTotalScrollBackOffset: Integer
}
Set an offset for the onTotalScrollBack option. For example, setting onTotalScrollBackOffset: 100 will trigger the onTotalScrollBack callback 100 pixels before the beginning of scrolling is reached.

Set live: true when you need to add scrollbar(s) on elements that do not yet exist in the page. These could be elements added by other scripts or plugins after some action by the user takes place (e.g. lightbox markup may not exist untill the user clicks an link). If you need at any time to disable or enable the live option, set live: "off" and "on" respectively. You can also tell the script to disable live option after the first invocation by setting live: "once".
liveSelector: string
Set the matching set of elements (instead of the current selector) to add scrollbar(s), now and in the future.

Plugin methods

update

Usage $(selector).mCustomScrollbar("update");

Call the update method to manually update existing scrollbars to accomodate new content or resized element(s). This method is by default called automatically by the script (via updateOnContentResize option) when the element itself, its content or scrollbar size changes.

scrollTo

Usage $(selector).mCustomScrollbar("scrollTo",position);

Call the scrollTo method to programmatically scroll the content to the position parameter. Position parameter can be a string (e.g. "#element-id", "bottom", "left" etc.), an integer indicating a number of pixels to scroll-to (e.g. 100), an array for y/x axis (e.g. [100,100]), a js/jQuery object, a function etc.

Examples

Scroll to the last element within your content

$(".content").mCustomScrollbar("scrollTo","last");

Scroll to element with id el-1

var elID="#el-1";
$(".content").mCustomScrollbar("scrollTo",elID);

scrollTo parameter

$(selector).mCustomScrollbar("scrollTo",String);
Scrolls to element position, string value can be any unique id, class etc.
$(selector).mCustomScrollbar("scrollTo","top");
Scrolls to top (vertical scrollbars)
$(selector).mCustomScrollbar("scrollTo","bottom");
Scrolls to bottom (vertical scrollbars)
$(selector).mCustomScrollbar("scrollTo","left");
Scrolls to left-end (horizontal scrollbars)
$(selector).mCustomScrollbar("scrollTo","right");
Scrolls to right-end (horizontal scrollbars)
$(selector).mCustomScrollbar("scrollTo","first");
Scrolls to first element’s position within the content
$(selector).mCustomScrollbar("scrollTo","last");
Scrolls to last element’s position within the content
$(selector).mCustomScrollbar("scrollTo",Integer);
Scrolls to number of pixels, e.g. $(selector).mCustomScrollbar("scrollTo",200);

Method option parameters

scrollInertia: Integer
Scroll-to animation speed, value in milliseconds. Example:
$(selector).mCustomScrollbar("scrollTo","bottom",{
  scrollInertia:3000
});
moveDragger: Boolean
Scroll scrollbar dragger (instead of content) to a number of pixels, values: true, false. Example:
$(selector).mCustomScrollbar("scrollTo",80,{
  moveDragger:true
});
callbacks: Boolean
Trigger user defined callbacks after scroll-to completes, values: true, false. Example:
$(selector).mCustomScrollbar("scrollTo","left",{
  callbacks:false
});
timeout: Integer
Set a timeout for the method (the default timeout is 60 ms in order to work with automatic scrollbar update), value in milliseconds. Example:
$(selector).mCustomScrollbar("scrollTo","top",{
  timeout:1000
});

stop

Usage $(selector).mCustomScrollbar("stop");

Stops running scrolling animations. Usefull when you wish to interupt a previously scrollTo call.

disable

Usage $(selector).mCustomScrollbar("disable");

Calling mCustomScrollbar’s disable method will temporarily disable the scrollbar. Disabled scrollbars can be re-enable by calling the update method.

Method parameters

$(selector).mCustomScrollbar("disable",true);
Disable custom scrollbar and reset content’s scrolling position.

Example of using disable method

destroy

Usage $(selector).mCustomScrollbar("destroy");

Calling destroy method will completely remove the custom scrollbar and return the element to its original state.

Example of using destroy method

Styling the scrollbars

Style your scrollbar(s) using the jquery.mCustomScrollbar.css file which contains the default scrollbar style plus a number of ready-to-use themes. You can directly change the default styling or you can keep it and add additional styles for each scrollbar.

You can have separate styling for each of your scrollbars on the same page, either by giving your content blocks different class names or ids or simply by targeting them in your css like this:

.mCSB_1_scrollbar .mCSB_dragger .mCSB_dragger_bar{
    /* 1st scrollbar dragger style... */
}
.mCSB_2_scrollbar .mCSB_dragger .mCSB_dragger_bar{
    /* 2nd scrollbar dragger style... */
}
.mCSB_3_scrollbar .mCSB_dragger .mCSB_dragger_bar{
    /* 3rd scrollbar dragger style... */
}

…and so on. Each content block in your document that has custom scrollbars gets automatically an additional unique class in the form of _mCS_+index number (e.g. _mCS_1) based on its index number within the DOM. Also, an additional id in the form of mCSB_+index number is generated for each .mCustomScrollBox div. This way you can easily target and style any scrollbar using its parent class name or id.

Custom scrollbar layout

User-defined callbacks

You can trigger your own js function(s) by calling them inside mCustomScrollbar callbacks option parameter

$(".content").mCustomScrollbar({
    callbacks:{
        onScroll:function(){
            myCustomFn(this);
        }
    }
});

function myCustomFn(el){
    console.log(el.mcs.top);
}

In the example above, each time a scroll event ends and content has stopped scrolling, the content’s top position will be logged in browser’s console. There are available callbacks for each step of the scrolling event:

  • onScrollStart – triggers the moment a scroll event starts
  • whileScrolling – triggers while scroll event is running
  • onScroll – triggers when a scroll event completes
  • onTotalScroll – triggers when content has scrolled all the way to bottom or right
  • onTotalScrollBack – triggers when content has scrolled all the way back to top or left

You can set an offset value (pixels) for both onTotalScroll and onTotalScrollBack by setting onTotalScrollOffset and onTotalScrollBackOffset respectively. For example, the following will trigger the callback function when content has scrolled to bottom minus 100 pixels

$(".content").mCustomScrollbar({
    callbacks:{
        onTotalScroll:function(){
            console.log("scrolled to bottom");
        },
    onTotalScrollOffset:100
    }
});

Returning values

The script returns a number of values and objects related to scrollbar

  • this – the original element containing the scrollbar(s)
  • this.mcs.content – the original content wrapper as jquery object
  • this.mcs.top – content’s top position (pixels)
  • this.mcs.left – content’s left position (pixels)
  • this.mcs.draggerTop – scrollbar dragger’s top position (pixels)
  • this.mcs.draggerLeft – scrollbar dragger’s left position (pixels)
  • this.mcs.topPct – content vertical scrolling percentage
  • this.mcs.leftPct – content horizontal scrolling percentage
  • this.mcs.direction – content’s scrolling direction (y or x)

Example

$("#content_1").mCustomScrollbar({
    callbacks:{
        whileScrolling:function(){
            myCustomFn(this);
        }
    }
});

function myCustomFn(el){
    var msg="Content inside the element with id '"+el.attr("id")+"' has scrolled "+mcs.topPct+"%";
  console.log(msg);
}

    Love the scroller, works awesome.

    I’m having a slight issue with it loading in ie7. For some reason the scroller appears on the right side and not the left. Any suggestions? Here’s the code I’m using:

    http://www.mstechsolutions.com/tmp/IE7.png
    http://www.mstechsolutions.com/tmp/CORRECT.png

    /* content block 1 */
    #mcs_container{position:relative;}
    #mcs_container .customScrollBox{position:relative; height:100%; overflow:hidden;}
    #mcs_container .customScrollBox .content{clear:both;}

    #mcs_container .customScrollBox{position:relative; height:100%; overflow:hidden;}
    #mcs_container .customScrollBox .container{position:relative; width:320px; top:0; float:left;}
    #mcs_container .customScrollBox .content{clear:both;}
    #mcs_container .customScrollBox .content p{padding:0 5px;}
    #mcs_container .customScrollBox .content p.alt{padding:10px 5px; margin:10px 0;}
    #mcs_container .customScrollBox img{border:5px solid #fff;}

    #mcs_container .scrollUpBtn,#mcs_container .scrollDownBtn{position:absolute; display:inline-block; width:11px; height:5px; margin-right:12px; text-decoration:none; right:0; filter:alpha(opacity=100); }
    #mcs_container .scrollUpBtn{top:0px; background:url(../images/mcs_btnUp.png) center center no-repeat; left:0}
    #mcs_container .scrollDownBtn{bottom:0px; background:url(../images/mcs_btnDown.png) center center no-repeat; left:0}
    #mcs_container .scrollUpBtn:hover,#mcs_container .scrollDownBtn:hover{filter:alpha(opacity=60); -moz-opacity:0.60; -khtml-opacity:0.60; opacity:0.60;}

    #mcs_container .dragger_container{position:relative; width:1px; height:149px; margin:6px 0px 0 5px; background:#cbbfbb; cursor:pointer;}
    #mcs_container .dragger{position:absolute; width:12px; height:15px; background:url(../images/scroll-dragger.gif) no-repeat; text-align:center; line-height:30px; overflow:hidden; cursor:pointer; left:-4px}
    #mcs_container .dragger_pressed{position:absolute; width:9px; height:16px; background:url url(../images/scroll-dragger.gif) no-repeat; text-align:center; line-height:16px; overflow:hidden; cursor:pointer; cursor:s-resize;}

      Hi, did you checked the actual demo or another implementation of the script? The demo is working well on Firefox (including version 5).

    Hey,
    I just don’t get it.
    I try to get this code into wordpress, but it doesn’t work.

    here’s my code:

    [somepics....]

    ….
    the scripts in my :

    <script src="/js/jquery.easing.1.3.js” type=”text/javascript”>
    <script src="/js/jquery.mousewheel.min.js” type=”text/javascript”>


    i noticed that wordpress uses the “enqueue script” function, but I don’t understand how it works.

    and that’s before the tag:

    $(window).load(function() {
    mCustomScrollbars();

      Hi Tim,

      A way to properly include jquery as well all the necessary scripts in your wordpress is this:
      In your wp theme directory you should have a functions.php file. Edit this file and add the following function at the top:
      function init_js(){ if(!is_admin()){ /* jquery (google CDN) */ wp_deregister_script('jquery'); wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js'); wp_enqueue_script('jquery'); /* jquery UI (google CDN) */ wp_deregister_script('jquery-ui-core'); wp_register_script('jquery-ui-core', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js'); wp_enqueue_script('jquery-ui-core'); /* easing */ wp_register_script('easing', get_bloginfo('template_directory') . '/js/jquery.easing.1.3.js','', '1.3', true); wp_enqueue_script('easing'); /* mousewheel */ wp_register_script('mousewheel', get_bloginfo('template_directory') . '/js/jquery.mousewheel.min.js','', '1.0', true); wp_enqueue_script('mousewheel'); /* custom scrollbar */ wp_register_script('mCustomScrollbar', get_bloginfo('template_directory') . '/js/jquery.mCustomScrollbar.js','', '1.0', true); wp_enqueue_script('mCustomScrollbar'); } } add_action('init', 'init_js');

      This includes jquery and jquery UI (one time only) from google CDN and the rest of the scripts from the directory js inside your themes folder (you can change the path to where your scripts reside).

      You should also not forget to link jquery.mCustomScrollbar.css in your header.php as well as to add the script call in your footer.php or on the template you need.

    If you get the scroller going in reverse check lines 318 and just
    targY = Math.abs(targY) * -1;
    to ensure it’s negative since for some reasons with dyn loaded content (esp. images) the targY stuff ends up being positive instead of neg.

    Hi,
    I have a question that involves cross-browser compatability and the user’s default font setting for the browser which they are using. If a users browser font size is set to be larger causing text to overflow, how do you have the dragger appear and reappear depending on the scale of the box?

    I’m trying to integrate the Custom Content Scroller in a WP E-Commerce Shopping Cart widget and there’s definitely some issues where the content either does not scroll at all or it scrolls but in the wrong direction. I’m wondering how feasible it is to incorporate this into a tight PHP script? The page in question is for a Rock Fashion site and can be viewed here.

    Hi again Malihu

    I’ve solved the problem with applying your scrollbars to form-based content, so just thought I’d post an explanation in case it’s helpful to you or anyone else.

    First thing is the html needs to be re-arranged slightly – because you have the “dragger container” div inside of the “customScrollBox” div, when you tab between form fields and the browser repositions the content, the scrollbar moves with it. There’s actually no need for the scrollbar to be inside that “overflow:hidden” div, so just move it outside. I actually think the best way is to define the scrollbar div first, and float it right instead of left. Obviously it may be necessary to fiddle with CSS a bit to maintain the page layout depending on the situation. So I’ve changed the html structure to something like this:

    … content …

    and the CSS for “dragger_container”:

    .dragger_container { position: relative; float: right; width: 0px; height: 300px; ….}

    Once that’s done the scrollbar no longer gets “lost” when the browser repositions the content, but of course it still doesn’t scroll without some extra jQuery code. This was actually pretty simple to implement once I worked out what was going on with the rest of your code.

    Basically if the browser has moved the content in order to bring a form field into view, you need to move the “dragger” by the equivalent relative amount. So firstly you need to know the ratio of the scrollbar size to the content size to determine how much to move the dragger. After studying your code I realised you’re already doing this calculation, but – here’s a note on variable naming (as a long-time developer :) ) – you put this ratio value into a variable called “scrollAmount”. When I saw this I figured it contained a pixel amount value to be scrolled, but it doesn’t. So I’ve renamed this variable “scrollRatio” which makes a lot more sense (to me at least).

    So once you’ve got the ratio, determining how much to move the dragger is pretty much the reverse of what you do to work out how much the content should move when the dragger is dragged, i.e.:

    1) get the amount the content has moved (which is just it’s top position);
    2) negate that value, as obviously the dragger should move in the opposite direction to the content;
    3) divide by the “scroll ratio”.

    This needs to happen whenever a form field gets focus, as that’s when the browser has potentially repositioned the content. So to implement this I added the following to the jQuery code just before the Scroll function (the first line replaces your “scrollAmount” calculation – just to be clear):

    var scrollRatio = (totalContent – (visibleHeight / bottomSpace)) / draggerContainerHeight – draggerHeight);

    $(‘:input’, $customScrollBox_container).focus(function() {
    var contentTop = $customScrollBox_container.position().top;
    var newDraggerPos = (-contentTop / scrollRatio);
    $dragger.css(“top”, newDraggerPos);
    });

    This could probably be done in one line without all the extra variables, but just wanted to make it clear what I’m doing.

    Cheers.

        It’s not working for me (the html/css fix is fine, the jquery is where I’m having trouble), Dreamweaver says there’s a syntax error but I’m not good enough with jquery to figure it out. The program is showing the issue is with the ” / bottomSpace)) / ” part of the code (I understood where to put it, and to replace the line mentioned by the author). Any help would be appreciated, I’m using this for a WordPress site and it was working perfectly until I got to the “contact” page with the form!

    Hi Malihu

    First of all, good work with the plug-in. There seem to be numerous custom scrollbar plug-ins out there, but I really like how customisable yours is via CSS.

    I’ve been trying to use your plug-in on a project, but I’ve hit a problem – I’ve searched extensively and scoured all the previous comments here but I don’t think anyone else has mentioned this.

    The problem is, if you have a form containing text boxes etc within the scrollable content, when you tab between form fields the custom scrollbar html structure gets messed up if you tab to a field that is initially out of view.

    You can replicate this problem easily – just add a inside your “content” div, obviously with enough content to activate the scrollbar. Put a text field at the top of the form and another at the bottom. Click in the first text field so that it has focus, then hit the tab key to move to the next text field and you’ll see what happens.

    I can tell you exactly what’s happening and why – I just haven’t managed to find a solution to this yet! What happens is when the second text field gains focus, because it is out of sight within the overflow: hidden div, the browser automatically re-positions that div to bring the field into view. Because the browser does this automatically, no jQuery code is executed, so the scrollbar doesn’t scroll. In fact, the scrollbar div is moved up by exactly the amount required to bring the text field into view, so it disappears off the top of the content container (or at least partially disappears, depending on how much content there is).

    I think what is needed is to somehow capture the fact that the next field is out of view from each field’s blur and / or focus event, and force the content to scroll by the amount required to bring that field into view, before the browser automatically shifts the overflowed div. I don’t know if it’s possible though to prevent this automatic browser behaviour. Of course this needs to work in reverse as well, so when using shift-tab to go back through form fields the content will scroll back up.

    If I work out a solution to this I’ll let you know with another post; in the meantime I’ll leave it with you.

    Cheers.

    Awesome control. The dragger won’t display in FF5 though. I haven’t tried it on any earlier versions as I just upgraded my machine to FF5, but it definitely doesn’t display the dragger. The scroll still works with the up/down arrows and mousewheel though.

    I used the scroller in mcs_container(the first example). The only difference between my code and your example is that there are additional divs inside the “content” div. Could this be causing the FF5 dragger issue?

    Has anyone else had problems displaying the dragger in FireFox?

      The plugin works as expected in Firefox 5 as well on previous versions, so the issue you’re experiencing must have something to do with your implementation. You can check the demo on this post on ff5 to confirm that it works.

    This is what i use in my header:

      Hello Adam,

      If I’m not mistaken, the original lightbox (or lightbox version 2) uses prototype/scriptaculous. That might conflict with jquery. I’ll definately try to find some time to update this script to be more compatible with other js libraries but in the meantime try this:

      In your document, wrap the script with (function($){… and …})(jQuery); making it like this:
      <script> (function($){ $(window).load(function() { $("#mcs_container").mCustomScrollbar("vertical",400,"easeOutCirc",1.05,"auto","yes","yes",10); }); })(jQuery); </script>

      You may also need to add jQuery.noConflict(); right before (function($){. Depending on the order you load the libraries (prototype, jquery etc.), adding this might help.

      Edit jquery.mCustomScrollbar.js and do the same by adding (function($){ as the 1st line and })(jQuery); as the last line of the script.

      Hope it helps.

        I also got a question to you about this script; is it possible to add a auto scroll when the user moves the cursor from left to right etc.? For example; if the user slightly moves the cursor to the right, the images (or content) scrolls to the right, etc. Is this possible to implement?

    Fantastic scrollbars! Easy to implement on my webpage and quite customizable. Something I haven’t been able to do, though, is enable a scroll when simply hovering over the scroll buttons, so that a click is not required. Do you know how we can add this functionality? I tried adding code such as onmouseover=”$(“.scrollUpBtn”).click();” or onmouseover=”BtnsScroll(‘down’);” but none of it seems to work.

      I too have tried (not very hard, I must admit) to get the roll-over/mouseover to trigger the .click() event.

      I tried adding both this…

      $('.scrollUpBtn').mouseover(function() { $(this).click(); });

      …and explicitly, ie. not using this…

      $('.scrollUpBtn').mouseover(function() { $('.scrollUpBtn').click(); });

      …after the $("#id").mCustomScrollbar(...); is initialised. But, without success.

      The .mouseover event triggers as/when it should but the simulated .click() isn’t carried out it seems.

      Anyone solved this? Someone must have done this already?! Please share!

        Since that I have tried replacing .click() with $(this).trigger('click');.

        And…

        $('.scrollUpBtn').bind('mouseover', function() { $(this).trigger('click'); });

        …again both without success.

        The .mouseover is still working, it’s just the click that isn’t?!*&^@#

        The 500 milliseconds delay is due to the fact that you call mCustomScrollbar as a callback after the fade-in animation is done (your fadeIn() lasts 500 milliseconds, thus the half-second delay). You can try putting mCustomScrollbar function call outside of fadeIn() like this:

        $(“#content, .contentWrapper.content-”+menuVal).fadeIn(500); $(“#mcs5_container”).mCustomScrollbar(“horizontal”,500,”easeOutCirc”,1,”auto”,”yes”,”no”,20);

        to see if it works.

      Not really. It would probably need the same amount of code anyway.
      On a live production website you could of course create a single js file containing all plugins (less html requests) and minify it. You could also download a custom built jquery ui containing only the functions your scripts need (less file-size).

    Now I’m trying to combine the jQuery resizing with this, and I’ve got an annoying problem.
    If I resize my box higher than my content, the scrollbar disappears.
    (In my case, I was like: neat! They even thought of this case! Though I’m also curious if I can make the scrollbar somehow remain visible.)
    The problem, is that after the scrollbar disappears, and I use my mousewheel, the content suddenly disappears too!

    but I don’t understand why dragger line (and dragger button) aren’t visible.
    Can you help me?

      Hello Fabio,

      Had a quick look into your document with firebug and seems that .container div overlaps and hides .dragger_container. Try to change your css properties of either one of these.

    I love the plugin, but I am still trying to get it work on my wordpress project. The problem I am facing now is that it only works when I place the loading tags for the scripts (jquery.min.js, jquery-ui.min.js, jquery.easing.1.3.js, jquery.mousewheel.min.js”) below the
    tag in the header.

    But when I do that, one of my wordpress navigation plugins stops to work…When I move the “script”-tags ABOVE the wordpress tag then my wordpress navigation plugin works, but then your custom scrollbar doesn’t work anymore… :-(

    The navigation plugin I am referring to is this: http://www.designchemical.com/blog/index.php/wordpress-plugins/wordpress-plugin-jquery-vertical-accordion-menu-widget/

    Any idea to how I can resolve this problem?

      Hi,

      if you want to add the jQuery library to WordPress you need to use the enqueue_scripts function. Otherwise when you load jquery manually it will overwrite any jquery plugins, which have loaded previously.

      If you are going to stick with the jquery menu plugin then this automatically loads jquery for you so you can include the above code but just miss out the actual jquery file

    Thanks for the terrific plug-in.

    I think I found a small bug and a fix for it: the mouse-wheel event hander should be detached even when no scroll bar is necessary because of the short contents.

    This causes a problem on Chrome (mine is 12.0.742.91) when the stuff to which the customized scrollbar applies is dynamically generated. You can see it when the following conditions hold:
    – the whole page is long to have the browser scrollbar
    – the area using the lib gains its stuff dynamically
    – the area has some long contents to make the customized scrollbar appear
    and then is replaced by some shorter to make the scrollbar disappear
    – the page scrollbar from the browser is not at its top
    – now using the mouse wheel on the area messes up its contents.

    Hope this helps.

      Hi duncan,
      The plugin works well on ie9. The demo works perfectly well for me (re-check your implementation to see if any css property breaks the script).

    “Ignore both the above, all working now :)”

    Ggnn.. I hate when people do this. Would it be so hard to provide an answer?

    I had the same problem (scrollbar disappearing after load). The problem was that my content (text) was in a DIV container which himself had a determinated height (css) property. I simply removed the height so this JQuery plug-in could do the work, i.e. get the proper height in a dynamic way.

    Hope this helps.

    Sir,

    Forget my Question # 2 above. I solved the problem. I saw isHrisov’s comment above and aplied it to horizontal scrolling: I put this:

    $customScrollBox.css(“overflow”, “hidden”);
    $dragger_container.css(“display”, “block”);

    right after:

    if($customScrollBox_container.width()>visibleWidth){ //enable scrollbar if content is long

    thank you so much for this ass-kicking script! keep on rocking! ;)
