获取网页分辨率及页面大小

javascript脚本判断网页分辨率:

var a=screen.width;//宽度

screen.height //高度

根据分辨率加载不同的flash:

<scripttype="text/javascript">
if(screen.width>1100)
Insert_Flash('flashcontent',"1280.swf","100%",105);
else
Insert_Flash('flashcontent',"1024.swf","100%",105);
</script>

取得当前页面宽度和高度:

<scripttype="text/javascript">
<!--
vara=document.body.clientWidth;
varb=document.body.clientHeight;
alert("当前页面宽度:"+a+",高度:"+b);
//-->
</script>

ie全屏页面(无滚动条)为分辨率-4,即1020或者1276.
