我已经创建了Web应用程序，我要在其中突出显示所选菜单。
以下是我所拥有的
<div style="width: 80%;" align="left" >
<span style="display:inline-block;" align="left" >
<div id="menubar" class="grid-block">
<nav id="menu">
<ul class="menu menu-dropdown ">
<li class="level1 item101 active">
<a href="index.xhtml" class="level1">
<span>
<span class="icon" style="background-image: url('images/menu/icon_menu_home.png');background-repeat: no-repeat; background-position: top center">
</span>

</span>
</a>
</li>
<li class="level1 item102 parent makeSpace default"
style="#{!PersonalInformationDataBean.pageViewData.contains('registerForPatentss') && !PersonalInformationDataBean.pageViewData.contains('success') && !PersonalInformationDataBean.pageViewData.contains('getReportss') && !PersonalInformationDataBean.pageViewData.contains('searhPatentss') ?'display:none':'display:inherit'};">
<a href="" class="level1 parent">

</ul>
</nav>
</div>

</div>
这给我的输出如下（它不一样，但是有点像这样）。
Home | Projects | Administrative
| |
| |
|- Men 1 |- Ad 1
|- Men 2 |- Ad 2
|- Men 3 |- Ad 3
现在我要做的是
当选择Men 1时，
<li class="level1 item102 parent makeSpace default"应更改为<li class="level1 item102 parent makeSpace active"，即取出default并加入active班级。当我单击
Ad 2时，<li class="level1 item102 parent makeSpace default"应该更改为<li class="level1 item102 parent makeSpace active"任何想法如何做到这一点？我在线检查，但是我得到的示例是针对0级菜单的。
最佳答案
请参见demo
jQuery的：
$("#menubar").on("click","li",function(e){
e.preventDefault();
e.stopPropagation();
if($(this).hasClass("active"))
{
$(this).removeClass("active").addClass("default");
}
else
{
$(this).addClass("active").removeClass("default");
}
});
