我想要一种效果：用javascript 和div 实现展开和收缩 div 层的功能！100 分，必结贴！
假如 pub.aspx 页中有如下代码：
<tr>
<td colSpan= "2 ">
这里放一个按钮，控制以下 <div id= "divOrders "> 层的伸展与收缩
</td>
</tr>
<tr>
<td colSpan= "2 ">
<div id= "divOrders ">
<table>
<tr>
<td> 这里是工作单内容 </td>
</tr>
</table>
</div>
</td>
</tr>
------------------------------------------
我就是想通过 点击按钮,实现收缩与展开 div 层中的内容
， 要如何能办到呢？
------解决方案--------------------
function load(Div,image)
{
var a=document.getElementById(Div).style.display;
if(a== " ")
{
hiddena(Div,image);
}
else if(a== "none ")
{
showa(Div,image);
}
}

function hiddena(Div,image)
{
document.getElementById(Div).style.display= "none ";
document.getElementById(image).style.background= "url(image/ico_down.gif) no-repeat scroll right bottom ";
}
function showa(Div,image)
{
document.getElementById(Div).style.display= " ";
document.getElementById(image).style.background= "url(image/ico_up.gif) no-repeat scroll right bottom ";
