回复讨论(解决方案)
if(myBoolean == true)
{
tree.value="-";
list.style.display="block";
myBoolean=false;
}
else
{
tree.value="+";
list.style.display="none";
myBoolean=true;
}
改成下面的就好了
IE8 IE 9 FF 都可以
写那么多，只要一句就可以实现了。。

你的不符合标准。

下面改装：
<script type="text/javascript"> $(function () { var ss = $('#catalog').find('li').not($('#catalog').find('li').eq(0)); ss.hide(); var x = 0; $('#tree').click(function () { if(x == 0) { ss.show(); $('#tree').val('-'); x = 1; } else { ss.hide(); $('#tree').val('+'); x = 0; } }) })</script></head><body><div id="catalog"><ul> <li><input type="button" value="+" id="tree"/>帮助文档：</li> <li><a href="http://www.baidu.com" target="content">办公室</a></li> <li>绘图室</li></ul></div>
