I ♥ BiGBaNG ♛ VIP: 鼠标点击时的烟花效果

效果图 ↓

这个工具就是我现在用着的，当鼠标点击时会有烟花效果

1. Design - Layout - Add A Gadget - HTML/Javascript
2. Copy down the code..

<script type="text/javascript">
// <![CDATA[
var sparks=75; // how many sparks per clicksplosion
var speed=33; // how fast - smaller is faster
var bangs=5; // how many can be launched simultaneously (note that using too many can slow the script down)
var colours=new Array('#fde4d3', '#fde4d3', '#fde4d3', '#fde4d3', '#fde4d3', '#fde4d3', '#fde4d3'); 
//
