基于jquery的获取浏览器窗口大小的代码

function getTotalHeight(){ 
if($.browser.msie){ 
return document.compatMode == "CSS1Compat"? document.documentElement.clientHeight : document.body.clientHeight; 
} 
else { 
return self.innerHeight; 
} 
} 

function getTotalWidth (){ 
if($.browser.msie){ 
return document.compatMode == "CSS1Compat"? document.documentElement.clientWidth : document.body.clientWidth; 
} 
else{ 
return self.innerWidth; 
} 
} 

var do_height = getTotalHeight(); 
var do_width = getTotalWidth(); 
alert("do_height=="+do_height+"\ndo_width=="+do_width);
