在javascript中得到当前窗口的高和宽 <body><SCRIPT LANGUAGE="JavaScript"> var s = "网页正文部分宽："+ document.body.clientWidth; s += "\r\n网页正文部分高："+ document.body.clientHeight; 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; alert(s); </SCRIPT>
<body><SCRIPT LANGUAGE="JavaScript">
var s = "网页正文部分宽："+ document.body.clientWidth;
s += "\r\n网页正文部分高："+ document.body.clientHeight;
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;
alert(s);
</SCRIPT>
document.body.scrollHeight
我想知道的是如何“先得到当前页面的宽度和高度”？
找不到body.offsetWidth，提示：undefined
