求高手看看,是不是兼容性问题,是的话如何修改下代码?跪谢。


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。。

另外,你的结构是有问题的。ul 里面写ul,那么第二个ul应该在li里面
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>
