<script>
/*使用方法：
============================
给相应的主菜单加事件
给文档的body加事件
初始化所有的菜单层不可见
============================
*/
//所有的菜单，如果添加需要扩展数组
var menuArr = new Array("compMenuDiv","productMenuDiv","helpDiv");
/*
控制菜单的显示和隐藏
divID 要显示的菜单层id
eventObj 激发下拉菜单的连接对象
*/
function dispMenu(divID,eventObj)
{
var divObj = document.getElementById(divID);
//getBoundingClientRect()用来获取任何一个页面元素相对文档原点的位置
//定位并显示指定菜单
divObj.style.top = eventObj.getBoundingClientRect().top + 13;
divObj.style.left = eventObj.getBoundingClientRect().left;
divObj.style.display = "inline";
//隐藏其余的菜单
for(var i = 0 ; i < menuArr.length ; i++)
{
if(menuArr[i] != divID){
document.getElementById(menuArr[i]).style.display = "none";
}
}
}
/*
窗体点击时隐藏所有菜单
*/
function closeAllMenu()
{
for(var i = 0 ; i < menuArr.length ; i++)
{
document.getElementById(menuArr[i]).style.display = "none";
}
}
</script>
你把DIV里的值磅定好就可以了`
