js获取电脑分辨率的思路及操作_javascript技巧

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);

function redirectPage() {
/*var url0x480 = "http://www.yourweb.com/0x480.html";**记得改相应的页面*/
var url800x600 = "index1.asp";
var url1024x768 = "index2.asp";
/*if ((screen.width == 0) && (screen.height == 480))
window.location.href= url0x480;*/
if (screen.width <= 800 )
window.location.href= url800x600;
else if ((screen.width >= 1024) )
window.location.href= url1024x768;
}
// End -->


这段代码是根据不同的屏幕显示不同的页面

下面是传递这个参数的
代码如下:

document.write("");
document.write(""' border=0 width=1 height=1>");
document.write("");
