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>
菜单效果如下：
