就是在settimeout那出错了，弄了半天了。
- JScript code
<script language="javascript">
<!--
function disp(x,h)
{
var mn=document.getElementById("maxNav_"+x);
var xn=document.getElementById("m"+x);
if (mn.style.display=="")
{
mn.style.display="none";
mn.style.height="0px";
xn.className="maxType";
}
else
{
for (var m=1;m<=3;m++)
{
document.getElementById("maxNav_"+m).style.display="none";
document.getElementById("maxNav_"+m).style.height="0px";
document.getElementById("m"+m).className="maxType";
}
mn.style.display="";
xn.e:'paddin
------解决方案--------------------
function dispa() {
i+=5;mn.style.height=i+"px";
if (i<120){setTimeout(function(){
dispa();
},1000)}
}
