谁能帮帮我把这段代码由mootools转成jq的？

Question

这段代码其实是用来高亮导航和显示子菜单的：
html代码结构大概如下：<ul class="GoodsDropNavs">
    <li class="n-cat-depth-1 nobg">
        <a class="depth-1" href="./">
            <em>
                首页
            </em>
        </a>
    </li>
    <li class="n-cat-depth-1">
        <a class="depth-1" href="/browse/category-16.html">
            <em>
                童装
            </em>
        </a>
        <table cellpadding="0" cellspacing="0" border="0" class="n-cat-popup"
        style="display:none;">
            <tr>
                <td class="n-cat-drop-2">
                    <ul>

</ul>下面这段代码用来高亮（即将当前地址栏的地址和导航比较，相等的话就加current样式）和鼠标移到大类的时候显示其隐藏的子菜单的，原来是用mootools写的，但我现在想用jq了，不过不熟悉mootools和jq，所以没能转化，谁能帮我转下，谢谢window.addEvent('domready',

Answer 1

我只会jquery这个mootools不了解啊。正在学习中

Answer 2

那个写得太复杂了。没那么麻烦,具体的分两步
第一步：功能实现
1：JQ写好基本功能
2：移动到大类时使用cookie保存大类的序号，点击子类时再次使用cookie保存子类的序号第二步：初始化
1:根据cookie中大类的序号，执行$('.depth-1').eq(序号).click()
2:根据cookie中保存的子类序号，去实现子类的选中状态切换

Answer 3

有道理，是我考虑不周全。那就只能从子类的href与当前的进行比对，然后往上查找大类，并触发大类的click事件了
