document.body.clientHeight没有返回正确的值(在下面的代码中返回0 onload和20 onresize)
<html>
<head>
<title>Untitled</title>
<script type="text/javascript" >
function height1()
{
document.getElementById("viewheight").innerHTML = document.body.clientHeight;
}
</script>
</head>
<body onload="height1();" onresize="height1();">
<span id="viewheight"></span>
</body>
</html>
