1.将下面的代码复制到 <body> 或者 <head> 内
<script language="JavaScript1.2"> /* Gradual-Highlight Image Script- ?Dynamic Drive (www.dynamicdrive.com) For full source code, installation instructions, 100's more DHTML scripts, and Terms Of Use, visit dynamicdrive.com */ function high(which2){ theobject=which2 highlighting=setInterval("highlightit(theobject)",50) } function low(which2){ clearInterval(highlighting) which2.filters.alpha.opacity=20 } function highlightit(cur2){ if (cur2.filters.alpha.opacity<100) cur2.filters.alpha.opacity+=5 else if (window.highlighting) clearInterval(highlighting) } </script>
2.在你想加上效果的图片代码上加入
style="filter:alpha(opacity=40)" onMouseover="high(this)" onMouseout="low(this)"
如下:
<img src="img/first.gif" width="97" height="100"
style="filter:alpha(opacity=40)" onMouseover="high(this)" onMouseout="low(this)"
