实现Web页面上的右键快捷菜单

样式代码：

<style type="text/css">
body{font: 9pt "宋体"; margintop: 0px ; color: red; background: #ffffff}
a.{ font: 9pt "宋体"; cursor: hand; font-size: 9pt ; color: blue; text-decoration: none }
a:active{ font: 9pt "宋体"; cursor: hand; color: #FF0033 }
a.cc:hover{ font: 9pt "宋体"; cursor: hand; color: #FF0033}
.box{ font: 9pt "宋体"; position: absolute; background: LightGrey; }
</style>

html代码如下：

<table id="itemopen" class="box" style="DISPLAY:none">
<tr>
<td>弹出菜单</td>
</tr>
<tr>
<td><a href="http://blog.csdn.net/Erickson/" class="cc">Erickson的专栏</a></td>
</tr>
<tr>
<td><a href="http://www.csdn.net" class="cc">CSDN</a></td>
</tr>
<tr>
<td><a href="http://www.google.com" class="cc">Google 搜索</a></td>
</tr>
<tr>
<td><a href="http://www.sohu.com" class="cc">搜狐</a></td>
</tr>
<tr>
<td><a href="http://www.yahoo.com" class="cc">Yahoo</a></td>
</tr>
<tr>
<td><a href="http://www.163.com" class="cc">163 网站</a></td>
</tr>
<tr>
<td><a href="http://sports.sina.com.cn" class="cc">新浪网体育</a></td>
</tr>
</table>

脚本代码：

右击鼠标显示快捷菜单：
<script language="JavaScript">
document.onmousedown = function popUp() {
menu = document.all.itemopen
if (event.button == 2) {
newX = window.event.x document.body.scrollLeft
newY = window.event.y document.body.scrollTop
menu.style.display = ""
menu.style.pixelLeft = newX
menu.style.pixelTop = newY
}
else if (event.button == 1)
{
menu.style.display = "none"
}
}
</script>

屏蔽IE默认的WinForm快捷菜单：
<script language="JavaScript">
var message="";
function clickIE()
{
if (document.all)
{
(message);
return false;
}
}
function clickNS(e)
{
if (document.layers||(document.getElementById&&!document.all))
{
if (e.which==2)
{
newX = window.event.x document.body.scrollLeft
newY = window.event.y document.body.scrollTop
menu = document.all.itemopen
if ( menu.style.display == "")
{
menu.style.display = "none"
}
else
{
menu.style.display = ""
}
menu.style.pixelLeft = newX
menu.style.pixelTop = newY
}
if (e.which==3)
{
(message);
return false;
}
}
}
if (document.layers)
{
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS;
}
else
{
document.onmouseup=clickNS;document.oncontextmenu=clickIE;
}
document.oncontextmenu=new Function("return false")
</script>
