javascript支持IE和firefox(FF)的渐变透明效果

function Clear (DataType ,DataThis, DataTime, DataInterval)
DataType 布尔值 - - 是否隐藏或显示
DataThis 元素 - - 被操作元素
DataTime 数字 - - 发生渐变时间
DataInterva 数字 - - 渐变刷新间隔

以下是HTML网页特效代码，

渐变

0.5, Test, parseInt(Math.random() * 2000), 10)" type="button" value="随意的渐变">

检测Test是否隐藏

var Test = document.getElementById('Test')

var SmallWay = {}

var HaInterval = ( !isNaN(DataInterval) ) ? parseInt(DataInterval) : 10
var HaTime = ( !isNaN(DataTime) ) ? parseInt(DataTime) : 1000

var HaOpacity = DataThis.getAttribute("SmallWay_Show_OpacityId")
if ( HaOpacity == null ) {
HaOpacity = ( DataThis.style.display != "none" ) ? 100 : 0
DataThis.style.filter = "Alpha(Opacity=" + HaOpacity + ")"
DataThis.style.cssText = DataThis.style.cssText.replace(/;-moz-opacity:.*?;/gi, "") + ";-moz-opacity:" + (HaOpacity / 100)
