css渐隐效果

今天找adonis要了段渐隐的效果代码,为了方便记录就丢这里了

由于他不要版权,我就厚颜无耻的帮他当原创写了,哈哈!!

<SCRIPT language=javascript>
var intDelay=20; 
var intInterval=2;
function GradientShow()
 {LayerMenu.filters.alpha.opacity+=intInterval;
 if (LayerMenu.filters.alpha.opacity<100) setTimeout("GradientShow()",intDelay);}
function GradientClose()
 {LayerMenu.filters.alpha.opacity-=intInterval;
 if (LayerMenu.filters.alpha.opacity>20)
 {setTimeout("GradientClose()",intDelay);
 }}
</SCRIPT>
<IMG id=LayerMenu onmouseover=GradientShow() style="FILTER: alpha(opacity=20)" onmouseout=GradientClose() src="/images/reply5.gif">
