标签：js javascript js菜单
主要代码：
<SCRIPT language="javascript">
function showsubmenu(sid){
var ele;
//先关闭其他的
for(var i=1;i<10;i++){
ele = document.getElementById("submenu" + i);
if(ele!=null && i!=sid){
ele.style.display="none";
}
}
//显示点击的菜单
whichEl = document.getElementById("submenu" + sid);
if (whichEl.style.display == "none"){
whichEl.style.display="";
}else{
whichEl.style.display="none";
}
}
</SCRIPT> 实现思路：通过获取竖立表格的各行元素，用ele.style.display="none";和whichEl.style.display="";分别控制达到隐藏和显示的作用。
