在javascript中得到当前窗口的高和宽
<body><SCRIPT LANGUAGE="JavaScript">
var s = "网页可见区域宽："+ document.body.clientWidth;
s += "\r\n网页可见区域高："+ document.body.clientHeight;
s += "\r\n网页可见区域高："+ document.body.offsetWeight +" (包括边线的宽)";
s += "\r\n网页可见区域高："+ document.body.offsetHeight +" (包括边线的宽)";
s += "\r\n网页正文全文宽："+ document.body.scrollWidth;
s += "\r\n网页正文全文高："+ document.body.scrollHeight;
s += "\r\n网页被卷去的高："+ document.body.scrollTop;
s += "\r\n网页被卷去的左："+ document.body.scrollLeft;
s += "\r\n网页正文部分上："+ window.screenTop;
s += "\r\n网页正文部分左："+ window.screenLeft;
s += "\r\n屏幕分辨率的高："+ window.screen.height;
s += "\r\n屏幕分辨率的宽："+ window.screen.width;
s += "\r\n屏幕可用工作区高度："+ window.screen.availHeight;
s += "\r\n屏幕可用工作区宽度："+ window.screen.availWidth;
s += "\r\n页面高度："+document.documentElement.clientHeight;
alert(s);
</SCRIPT>
在取得document.body时，也要注意html页面的DOCTYPE声明，
1，如果!DOCTYPE声明为<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">，document.body.clientHeight在我机器页面上取得就是1206，这显然比“网页可见区域高”高了许多，而document.documentElement.clientHeight显示是610。
2，如果!DOCTYPE声明为<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">，document.body.clientHeight的值是610，
而document.documentElement.clientHeight显示是0。
所以我们得根据!DOCTYPE声明来选择document.body.clientHeight和document.documentElement.clientHeight来取得页面高度。
以下是测试页面的html代码：
代码1:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
