检测屏幕宽度,并设置为id为frame的div宽度, 根据自己网页的最大宽度来调节,小demo最大宽度为1440

代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>无标题文档</title> 
<script src="js/jquery.min.js" type="text/javascript"></script> 
<script> 
function onWidthChange(){ 
var w=$(window).width(); 
x=(w-1440)/2; 
$("#frame").css("width",w); 
if(w<1024){ 
$("#frame").css("overflow","visible"); 
$("#webContent").css("margin-left",x); 
}else if(1024<w<1440){ 
$("#frame").css("overflow","hidden"); 
$("#webContent").css("margin-left",x); 
} 
setTimeout(onWidthChange,0); 
}; 
</script> 
</head> 
<body> 
<div id="frame" style="overflow:hidden;"> 
<div id="webContent"> 
//内容 
</div> 
</div> 
</body> 
</html>
