高手请看下面代码:在IE中能正常显示光棒效果,在火狐里没有效果
<script>
var  highlightcolor='#c1ebff';
//此处clickcolor只能用win系统颜色代码才能成功,如果用#xxxxxx的代码就不行,还没搞清楚为什么:(
var  clickcolor='#51b2f6';
function  changeto(){
var source=event.srcElement;
if  (source.tagName=="TR"||source.tagName=="TABLE")
return;
while(source.tagName!="TD")
source=source.parentElement;
source=source.parentElement;
cs  =  source.children;
//alert(cs.length);
if  (cs[1].style.backgroundColor!=highlightcolor&&source.id!="nc"&&cs[1].style.backgroundColor!=clickcolor)
for(i=0;i<cs.length;i++){
cs[i].style.backgroundColor=highlightcolor;
}
}function  changeback(){
if  (event.fromElement.contains(event.toElement)||source.contains(event.toElement)||source.id=="nc")
return
if  (event.toElement!=source&&cs[1].style.backgroundColor!=clickcolor)
//source.style.backgroundColor=originalcolor
for(i=0;i<cs.length;i++){
cs[i].style.backgroundColor="";
