很多浏览器对height:100%的支持都不是很好，这里提供一种js解决
div#test始终布满浏览器
<!DOCTYPE html>
<html>
<head>
<title>Test by Josh</title>
<style type="text/css">
* { padding:0; margin:0; }
#test { background:#aaa; height:100%; width:100%; }
</style>
<script type="text/javascript">
window.onload = function() {
var height = getViewportHeight();
alert("这是脚本运行前的效果。点“确定”查看运行后的效果。");
if(height > 0)
document.getElementById("test").style.height = height + "px";
}
function getViewportHeight() {
var h = 0;
if(self.innerHeight)
h = window.innerHeight;
else if(document.documentElement && document.documentElement.clientHeight)
h = document.documentElement.clientHeight;
else if(document.body)
h = document.body.clientHeight;
return h;
}
</script>
</head>
<body>
<div id="test">
<h1>Test</h1>
</div>
</body>
</html>
