Question

怎么用js把网页里多余的<UL></UL>代码去掉！

这样好像不行，

<script type="text/javascript">

if (abc123.innerHTML == '<UL></UL>')
abc123.innerHTML = '';

</script>

<div id=abc123>
<LI><A href="product/?type=list&classid=6" target=_self>LED 柔性灯条</A>
<UL></UL>
<LI><A href="product/?type=list&classid=7" target=_self>LED 硬灯条(铝槽)</A>
<UL></UL>
<LI><A href="product/?type=list&classid=8" target=_self>LED 天花灯</A>
<UL></UL>
<LI><A href="product/?type=list&classid=9" target=_self>LED 射灯</A>
<UL></UL>
</div>

<div id=abc123>
<LI><A href="product/?type=list&classid=6" target=_self>LED 柔性灯条</A>
<UL></UL>
<LI><A href="product/?type=list&classid=7" target=_self>LED 硬灯条(铝槽)</A>
<UL></UL>
<LI><A href="product/?type=list&classid=8" target=_self>LED 天花灯</A>
<UL></UL>
<LI><A href="product/?type=list&classid=9" target=_self>LED 射灯</A>
<UL></UL>
</div>

<script type="text/javascript">
//这段js要写在DIV的后面
document.getElementById('abc123').innerHTML=document.getElementById('abc123').innerHTML.replace(/\<\u\l\>\<\/\u\l\>/g,"");
</script>
