perfect-scrollbar ================= Tiny but perfect jQuery scrollbar plugin Why perfect-scrollbar? ------------------ I worked on a personal project recently, and I was trying to find the jQuery scrollbar plugin that's *perfect*. But there was no *perfect* scrollbar plugin. That's why I decided to make one. perfect-scrollbar is very tiny but *perfect* (for me, and maybe for the most of developers) jQuery scrollbar plugin. I hope you love this! Demo: http://noraesae.github.com/perfect-scrollbar/ What does *perfect* mean? --------------------- *perfect* means... * There should be no css change on any original element. * The scrollbar should not affect the original design layout. * The design of the scrollbar should be (nearly) fully customizable. * If the size of the container or the content changes, the scrollbar size and position should be able to change. Then perfect-scrollbar is really *perfect*? ------------------------------------------- Yes! the only thing that's not *perfect* is my English. * perfect-scrollbar has some requirements, but doesn't change or add any style on original elements. * perfect-scrollbar is designed not to have width or height. It's fixed on the right and bottom side of the container. * You can change nearly all css styles of the scrollbar. The scrollbar design has no dependency on scripts. * perfect-scrollbar support 'update' function. Whenever you need to update the size or position of the scrollbar, just update. * Additionally, perfect-scrollbar do use 'scrollTop' and 'scrollLeft', not absolute position or something messy. It's cool, isn't it? Install ------- You can download the latest stable version with download links in [Github Page](http://noraesae.github.io/perfect-scrollbar/). You also can find all releases in [Releases](https://github.com/noraesae/perfect-scrollbar/releases) page. If you want to use the development version of the plugin, use the source files which are not minified. They're in the `src` directory. The development version may be unstable, but some known bugs can be fixed. ``` git clone https://github.com/noraesae/perfect-scrollbar.git cd perfect-scrollbar/src ``` You can use [Bower](http://bower.io/) to install the plugin. The plugin is registered as `perfect-scrollbar`. ``` bower install perfect-scrollbar ``` Requirements ------------ To make this plugin *perfect*, some requirements were not avoidable. But they're all very trivial and there's nothing to worry about. * the container must have a 'position' css style. * the container must have an 'overflow:hidden' css style. * the scrollbar's position must be 'absolute'. * the scrollbar-x must have a 'bottom' css style, and the scrollbar-y must have a 'right' css style. The requirement below is for perfect-scrollbar &lt;= 0.3.4 * there must be the *one* content element(like div) for the container. Optional parameters ------------------- perfect-scrollbar supports optional parameters. ### wheelSpeed The scroll speed applied to mousewheel event. **Default: 10** ### wheelPropagation If this option is true, when the scroll reach the end of the side, mousewheel event will be propagated to parent element. **Default: false** ### minScrollbarLength When set to an integer value, the thumb part of the scrollbar will not shrink below that number of pixels. **Default: null** ### useBothWheelAxes When set to true, and only one (vertical or horizontal) scrollbar is visible then both vertical and horizontal scrolling will affect the scrollbar. **Default: false** ### useKeyboard When set to true, the scroll works with arrow keys on the keyboard. The element is scrolled only when the mouse cursor hovers the element. **Default: true** ### suppressScrollX When set to true, the scroll bar in X axis will not be available, regardless of the content width. **Default: false** ### suppressScrollY When set to true, the scroll bar in Y axis will not be available, regardless of the content height. **Default: false** ### scrollXMarginOffset The number of pixels the content width can surpass the container width without enabling the X axis scroll bar. Allows some "wiggle room" or "offset break", so that X axis scroll bar is not enabled just because of a few pixels. **Default: 0** ### scrollYMarginOffset The number of pixels the content height can surpass the container height without enabling the Y axis scroll bar. Allows some "wiggle room" or "offset break", so that Y axis scroll bar is not enabled just because of a few pixels. **Default: 0** ### includePadding When set to true, it uses `innerWidth` and `innerHeight` for the container size instead of `width` and `height`. When your container element has non-zero padding and the scrollbar layout looks weird, this option can be helpful. **Default: false** How to Use ---------- ```html <style> #Demo { position: 'relative'; } </style> <div id='Demo'> <div> ... </div> </div> ``` When the html document is like above, just use like this: ```javascript $('#Demo').perfectScrollbar(); ``` With optional parameters: ```javascript $("#Demo").perfectScrollbar({ wheelSpeed: 20, wheelPropagation: true, minScrollbarLength: 20 }) ``` If the size of your container or content changes: ```javascript $('#Demo').perfectScrollbar('update'); ``` If you want to destory the scrollbar: ```javascript $('#Demo').perfectScrollbar('destroy'); ``` If you want to scroll to somewhere, just use scroll-top css and update. ```javascript $("#Demo").scrollTop(0); $("#Demo").perfectScrollbar('update'); ``` Also you can get the informations about how to use the plugin from example codes in the `examples` directory of the source tree. Very helpful friends -------------------- perfect-scrollbar supports [jquery-mousewheel](https://github.com/brandonaaron/jquery-mousewheel). If you want to use mousewheel features, please include jquery-mousewheel before using perfect-scrollbar. If you want to make this plugin's update function more responsive, [jquery-resize](https://github.com/cowboy/jquery-resize) can be helpful. Contribution ------------ #### Please read [Contributing](https://github.com/noraesae/perfect-scrollbar/wiki/Contributing) in the wiki before making any contibution. I *really* welcome contributions! Please feel free to fork and issue pull requests when... * You have a very nice idea to improve this plugin! * You found a bug! * You're good at English and can help my bad English! For IE problems, please refer to [IE Support](https://github.com/noraesae/perfect-scrollbar#ie-support) IE Support ---------- This plugin supports old IE browsers in the **minimum** range. The plugin is tested in IEs >= IE6 and works(not well, but works). **But the project will not accept the patches to fix IE problems in IE 6/7/8.** From jQuery 2.0, jQuery also will not support IE 6/7/8. I also think that supporting old browsers really breaks the web development conventions. When old IEs should be supported, please fork the project and make patches personally.
