忙逐行解一下做菜的java本
！

[解决办法]
<td height= "25 "> <a href= "javascript: " onClick= "if (im1.style.display== 'block ')im1.style.display = 'none ';else im1.style.display= 'block ' "> 文管理 </a> </p> ' '显示和隐藏菜单，点击的时候是隐藏的话，则展开，展开的话则隐藏。
<table width= "100% " border= "0 " id= "im1 " style= "display:none "> ' '默认是隐藏状态。
后面的就不用解释了吧？
[解决办法]
im1.style.display== 'block ';(显示)
im1.style.display = 'none;(不显示)
im1是你table的id啊！
table width= "100% " border= "0 " id= "im1 "
