HTML树形菜单伸缩问题

<br><SPAN><IMG id="Image_Closed" style="DISPLAY: none" onclick="this.style.display='none'

Text_Closed.style.display='inline'

Image_Open.style.display='inline'

Text_Open.style.display='inline'"

src="pic/m_o.gif"><IMG id="Image_Open<%= i %>" onclick="this.style.display='none'

Image_Closed.style.display='inline'

Text_Open.style.display='none'

Text_Closed.style.display='inline'"

src="pic/m_c.gif"></SPAN>

<SPAN id="Text_Closed">大目录

<SPAN id="Text_Open" style="DISPLAY: none">'主要是这句话进行修改下

<SPAN>

<br> <IMG src="pic/m_c.gif" />小目录<br>

</SPAN>

</SPAN>

</SPAN>

<table border="0" cellspacing="0" cellpadding="0">

一样的，用一个大表格，把它们竖向的框起来。

不太理解你要什么，看看下面这段代码实现的效果是你想要的吗？

<style>div{font-size:12pxcolor:redbackground-color: #EAEAE8border: 1 solid #1892B5padding: 1}</style>

<div id="main1" style="color:blue" onclick="document.all.child1.style.display=(document.all.child1.style.display =='none')?'':'none'" >

+ 主目录1</div>

<div id="child1" style="display:none">

<a href="#">- 子目录1</a><br>

<a href="#">- 子目录2</a><br>

<a href="#">- 子目录3</a><br>

<a href="#">- 子目录4</a>

</div>

<div id="main2" style="color:blue" onclick="document.all.child2.style.display=(document.all.child2.style.display =='none')?'':'none'" >

+ 主目录2 </div>

<div id="child2" style="display:none">

<a href="#">- 子目录1</a><br>

<a href="#">- 子目录2</a><br>

<a href="#">- 子目录3</a>

</div>
