Answer 3

<input  id="Button2" type="hidden" value="ShowDiv3" onclick="TestShowDiv(event,this)" />
<a href="#" onclick="javascript:TestShowDiv(event, document.getElementById('Button2'));void(0);"><img src='' border='0'></a>把Button隐藏,用img代替

Answer 4

那我
<img src="1.jpg"  id="Button2" onclick="TestShowDiv(event,this)" style="cursor:hand" />
不是更简单？
会不会造成多个对象产生？
