IE下onmouseout解决穿透不准的问题。(未测试)

function onmouseoutfun(e,o,fun)
{

if(window.navigator.userAgent.indexOf("Firefox")>=1)
{
var x = e.clientX +document.body.scrollLeft;
var y = e.clientY + document.body.scrollTop;
var left = o.offsetLeft;
var top = o.offsetTop;
var w = o.offsetWidth;
var h = o.offsetHeight;

if(y < top || y > (h + top) || x > left+ w || x
fun();
}
}

if(o.contains(e.toElement ) == false )
{
fun();
}
}
