编写相应程序代码即可。
代码如下:
<script>
function getInfo()
{
var s = "";
s += " 网页可见区域宽:"+ document.body.clientWidth;
s += " 网页可见区域高:"+ document.body.clientHeight;
s += " 网页可见区域宽:"+ document.body.offsetWidth + " (包括边线和滚动条的宽)";
s += " 网页可见区域高:"+ document.body.offsetHeight + " (包括边线的宽)";
s += " 网页正文全文宽:"+ document.body.scrollWidth;
s += " 网页正文全文高:"+ document.body.scrollHeight;
s += " 网页被卷去的高(ff):"+ document.body.scrollTop;
s += " 网页被卷去的高(ie):"+ document.documentElement.scrollTop;
s += " 网页被卷去的左:"+ document.body.scrollLeft;
s += " 网页正文部分上:"+ window.screenTop;
s += " 网页正文部分左:"+ window.screenLeft;
s += " 屏幕分辨率的高:"+ window.screen.height; s += " 屏幕分辨率的宽:"+ window.screen.width;
s += " 屏幕可用工作区高度:"+ window.screen.availHeight;
s += " 屏幕可用工作区宽度:"+ window.screen.availWidth;
s += " 你的屏幕设置是 "+ window.screen.colorDepth +" 位彩色";
s += " 你的屏幕设置 "+ window.screen.deviceXDPI +" 像素/英寸";
//alert (s);
}
getInfo();
</script>
