如何在CSS类中获取元素的属性集
问题描述：
我想读取元素的高度和宽度.
I want to read the element's height and width.
<style type="text/css">
.big {
height: 100px;
width: 100px
}
</style>
<div id="box1" style="width:50px; height=50px;"></div>
<div id="box2" class="big"></div>
对于box01，我可以使用height=getElementById("box01").style.height-很好.
For box01 I can use height=getElementById("box01").style.height - that's fine.
但是对于box02来说，它不起作用.它什么也不返回.
But for box02 it doesn't work. It returns nothing.
