网页宽度高度获取方法备忘

function gets()
{
var s ="网页可见区域宽："+ document.body.clientWidth;
s += "<br>网页可见区域高：" + document.body.clientHeight;
s += "<br>网页可见区域宽：" + document.body.offsetWidth +" (包括边线的宽)";
s += "<br>网页可见区域高：" + document.body.offsetHeight +" (包括边线的宽)";
s += "<br>网页正文全文宽：" + document.body.scrollWidth;
s += "<br>网页正文全文高：" + document.body.scrollHeight;
s += "<br>网页被卷去的高：" + document.body.scrollTop;
s += "<br>网页被卷去的左：" + document.body.scrollLeft;
s += "<br>网页正文部分上：" + window.screenTop;
s += "<br>网页正文部分左：" + window.screenLeft;
s += "<br>屏幕分辨率的宽：" + window.screen.width;
s += "<br>屏幕分辨率的高：" + window.screen.height;
s += "<br>屏幕可用工作区宽度：" + window.screen.availWidth;
s += "<br>屏幕可用工作区高度：" + window.screen.availHeight;
document.getElementById('dd').innerHTML = s;
}

你可以参考下面这个函数，这个函数是获取完整页面尺寸的函数（即你说的浏览器能看到的区域，不包括被滚动条卷去的区域）

-----------------------------js代码---------------------------------------------------------

<script>

function GetPageSize(){

    var xScroll, yScroll;

    if (window.innerHeight  &&  window.scrollMaxY) {

        xScroll = document.body.scrollWidth;

        yScroll = window.innerHeight + window.scrollMaxY;

    } else if (document.body.scrollHeight > document.body.offsetHeight){

        xScroll = document.body.scrollWidth;

        yScroll = document.body.scrollHeight;

    } else {

        xScroll = document.body.offsetWidth;

        yScroll = document.body.offsetHeight;

    }

    var windowWidth, windowHeight;

    if (self.innerHeight) {

        windowWidth = self.innerWidth;

        windowHeight = self.innerHeight;

    } else if (document.documentElement  &&  document.documentElement.clientHeight) {

        windowWidth = document.documentElement.clientWidth;

        windowHeight = document.documentElement.clientHeight;

    } else if (document.body) {

        windowWidth = document.body.clientWidth;

        windowHeight = document.body.clientHeight;

    }

    if(yScroll < windowHeight){

        pageHeight = windowHeight;

    } else {

        pageHeight = yScroll;

    }

    if(xScroll < windowWidth){

        pageWidth = windowWidth;

    } else {

        pageWidth = xScroll;

    }

    arrayPageSize = new Array(pageWidth,pageHeight,windowWidth,windowHeight)

    return arrayPageSize;

}

alert(GetPageSize());
