尝试使用此函数...，并在需要时调用它:)
Try this function... and call it when needed :)
function getViewPortSize()
{
var viewportwidth;
var viewportheight;
//Standards compliant browsers (mozilla/netscape/opera/IE7)
if (typeof window.innerWidth != 'undefined')
{
viewportwidth = window.innerWidth,
viewportheight = window.innerHeight
}
// IE6
else if (typeof document.documentElement != 'undefined'
&& typeof document.documentElement.clientWidth !=
'undefined' && document.documentElement.clientWidth != 0)
{
viewportwidth = document.documentElement.clientWidth,
viewportheight = document.documentElement.clientHeight
}
//Older IE
else
{
viewportwidth = document.getElementsByTagName('body')[0].clientWidth,
viewportheight = document.getElementsByTagName('body')[0].clientHeight
}
return viewportwidth + "~" + viewportheight;
}
