代码如下：
<script language="JavaScript1.2"> function changeto(highlightcolor){ source=event.srcElement if (source.tagName=="TR"||source.tagName=="TABLE") return while(source.tagName!="TD") source=source.parentElement if (source.style.backgroundColor!=highlightcolor&&source.id!="ignore") source.style.backgroundColor=highlightcolor } function changeback(originalcolor){ if (event.fromElement.contains(event.toElement)||source.contains(event.toElement)||source.id=="ignore") return if (event.toElement!=source) source.style.backgroundColor=originalcolor } </script> <!--以下是你代码是用来触发事件的，也是改变颜色的地方--> <table border="1" width="54%"> <tr onMouseover="changeto('#fff362')" onMouseout="changeback('white')"> <td width="100%">　</td> </tr> <tr onMouseover="changeto('#ff5525')" onMouseout="changeback('white')"> <td width="100%">　</td> </tr> <tr onMouseover="changeto('#ff2262')" onMouseout="changeback('white')"> <td width="100%">　</td> </tr> </table>
