var bodyWidth =document.body.clientWidth; //网页可见区域宽   

var bodyHeight =document.body.clientHeight; //网页可见区域高   

var bodyWidthWithBorder =document.body.offsetWidth; //网页可见区域宽(包括边线的宽)  

var bodyHeightWithBorder=document.body.offsetHeight; //网页可见区域高(包括边线的宽)   

var bodyWidthWithScroll =document.body.scrollWidth; //网页正文全文宽   

var bodyHeightWithScroll=document.body.scrollHeight; //网页正文全文高   

var bodyTopHeight =document.body.scrollTop; //网页被卷去的上边距   

var bodyLeftWidth =document.body.scrollLeft; //网页被卷去的左边距   

var windowTopHeight =window.screenTop; //网页正文部分上边距   

var windowLeftWidth =window.screenLeft; //网页正文部分左边距   

var screenHeight =window.screen.height; //屏幕分辨率的高   

var screenWidth =window.screen.width; //屏幕分辨率的宽   

var screenAvailHeight =window.screen.availHeight; //屏幕可用工作区高度
