类似SOHU图吧右键菜单的功能，使用JavaScript实现。下面是代码：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>自定义鼠标右键弹出式菜单</title>
<style type="text/css">

</style>
<script language="javascript">
//弹出菜单
function PopupMouseRightButtonUpMenu()
{
//显示菜单
if(MouseMenu.style.visibility=='visible') MouseMenu.style.visibility='hidden';
//如果是链接、文本区或输入框，则显示IE菜单
if (event.srcElement.tagName=='A' || event.srcElement.tagName=='TEXTAREA' || event.srcElement.tagName=='INPUT' || document.selection.type!='None')
return true;
else
{
//防止菜单出格
if (event.clientX+150 > document.body.clientWidth) MouseMenu.style.left=event.clientX+document.body.scrollLeft-150;
else MouseMenu.style.left=event.clientX+document.body.scrollLeft;
if (event.clientY+DivH > document.body.clientHeight) MouseMenu.style.top=event.clientY+document.body.scrollTop-DivH;
else MouseMenu.style.top=event.clientY+document.body.scrollTop;
MouseMenu.style.visibility='visible';
}
//禁止IE菜单
return false;
}
//画出菜单，但不显示
function DrawMouseRightButtonUpMenu(){
DivH=2;
//oSelection = document.selection;
