以上图均为有滚动条↑

width分析：

与滚动条无关

　　window.screen.width , window.screen.availWidth , window.innerWidth , window.outerWidth 显示屏的宽度

有滚动条

　　1.无竖的滚动条

　　　　document.body.scrollWidth 和 $(document).width() : 网页正文全文宽(包括 margin,border,padding,但不包括滚动条)；

　　2.有竖的滚动条

　　　　document.body.scrollWidth 和 $(document).width() : 网页正文全文宽(包括 margin,border,padding,但包括滚动条,会忽略滚动条)；

无滚动条

　　document.body.scrollWidth , $(document).width() , window.screen.width , window.screen.availWidth , window.innerWidth , window.outerWidth , $(window).width() 一样，为显示屏的宽度；

　　document.body.offsetWidth : 不包括margin

　　document.body.clientWidth : 不包括margin和border

　　$(document.body).width() ：不包括padding,border和margin

height分析：

height太乱了，老是变化！/(ㄒoㄒ)/~~
