body不能这么引用。并且直接这么写的话也不行，运行代码时body还没构造出来呢，应该用onload。
<html>
<head>
<title>T</title>
<script type="text/javascript">
var $=document.getElementById;
var winWidth = 0;
var winHeight = 0;
function findDimensions()
{
winWidth = $("main").clientWidth;
winHeight = $("main").clientHeight;
alert(winHeight);
alert(winWidth);
}
window.onload=findDimensions;
this.onresize=findDimensions;
</script>
</head>
<body id="main">
