本文实例讲述了jQuery获得document和window对象宽度和高度的方法。分享给大家供大家参考。具体如下：
<!DOCTYPE html>
<html>
<head>
<script src="js/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("button").click(function(){
var txt="";
txt+="Document width/height: " + $(document).width();
txt+="x" + $(document).height() + "\n";
txt+="Window width/height: " + $(window).width();
txt+="x" + $(window).height();
alert(txt);
});
});
</script>
</head>
<body>
<button>Display dimensions of document and window</button>
</body>
</html>
希望本文所述对大家的jQuery程序设计有所帮助。
