js 获取web界面宽度和高度的方法总结

function screenInfo(){

var s = "";

s += "\r\n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网页可见区域宽："+ document.body.offsetWidth +" (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;

alert(s);

}

var h=document.body.clientHeight-90;

document.getElementById('mainTable').style.height = h + 'px'; 通过这种方式可以动态修改 界面的高度和宽度
