代码如下：
<html xmlns="

">
<head runat="server">
<title>窗口大小</title>
</head>
<body onload="findDimensions();">
<h2 align="center">请调整浏览器窗口大小</h2>
<hr/>
<form action="#"method="get"name="form1"id="form1">
<!--显示浏览器窗口的实际尺寸-->
浏览器窗口的高度：<input type="text"name="availHeight"size="4"/><br/>
浏览器窗口的宽度：<input type="text"name="availWidth"size="4"/><br/>
</form>
<div id="div1"style="background-color:Gray; width:616px; height: 305px;"></div>
<script type="text/javascript">
var winWidth=0;
var winHeight=0;
function findDimensions() { //函数：获取尺寸
//获取窗口宽度
if (window.innerWidth) {
winWidth = window.innerWidth;
} else if ((document.body) && (document.body.clientWidth)) {
winWidth = document.body.clientWidth;
}
//获取窗口高度
if (window.innerHeight) {
winHeight = window.innerHeight;
}else if ((document.body) && (document.body.clientHeight)) {
winHeight = document.body.clientHeight;
}
//通过深入Document内部对body进行检测，获取窗口大小
if (document.documentElement && document.documentElement.clientHeight && document.documentElement.clientWidth) {
winHeight=document.documentElement.clientHeight;
winWidth=document.documentElement.clientWidth;
}
//结果输出至两个文本框
document.form1.availHeight.value=winHeight;
document.form1.availWidth.value = winWidth;
//设置div的具体宽度=窗口的宽度的%
if (document.getElementById("div1")) {
document.getElementById("div1").style.width = winWidth*0.98 + "px";
}
}
window.onresize=findDimensions;
</script>
</body>
</html>
