提示：最爲重要的就是
<script type="text/javascript">
var popup = window.createPopup();
var width;
var height;
function Pop_menu(divMenuList,width,height,toolbarMenuItem)
{
popup.document.body.innerHTML = divMenuList.innerHTML;
popup.show(0,24,width,height,toolbarMenuItem);
// 0 和 23 是相對於toolbarMenuItem元素左上角的座標點(x,y)
// width 顯示菜單的寬度
// height 顯示菜單的高度
// toolbarMenuItem 要彈出菜單的對象
}
</script>

還有就是：通過 window.createPopup().show () 彈出來的菜單實際上脫離了父頁面,所以父頁面上的樣式表對 彈出來的菜單界面是不起作用的。
