perfect-scrollbar

Tiny but perfect jQuery scrollbar plugin

Why perfect-scrollbar?

I worked on the 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 means perfect?

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?

Requirements

To make this plugin perfect, some requirements were not avoidable. But they're all very trivial and there's nothing to worry about.

  • there must be the one content element(like div) for the container.
  • the container must have a 'position' 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.

How to Use

<style>
  #Demo { position: 'relative'; }
</style>
<div id='Demo'>
  <div>
    ...
  </div>
</div>

When the html document is like above, just use like this:

$('#Demo').perfectScrollbar();

If the size of your container or content changes:

$('#Demo').perfectScrollbar('update');

If you want to destory the scrollbar:

$('#Demo').perfectScrollbar('destroy');

If you want to scroll to somewhere, just use scroll-top css and update.

$("#Demo").scrollTop(0);
$("#Demo").perfectScrollbar('update');

Very helpful friends

perfect-scrollbar supports 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 can be helpful.
