<a href="#" class="m" onclick="change(this);">1</a>
<ul id="b">

<a href="#" class="g" onclick="cg(this);">5</a>

</ul>
</li>
<li>
<a href="#" class="m" onclick="change(this);">2</a>
<ul id="b">
<li>
<a href="#" class="g" onclick="cg(this);">4</a>
<a href="#" class="g" onclick="cg(this);">5</a>
</li>
</ul>
</li>
<li>
<a href="#" class="m" onclick="change(this);">3</a>
<ul id="b">
<li>
<a href="#" class="g" onclick="cg(this);">4</a>
<a href="#" class="g" onclick="cg(this);">5</a>
</li>
</ul>
</li>
</ul>
</body>
</html>
我有两个ul，里面的li包含着多个a标签，我想实现的功能是，当我点击第一个ul下面的a标签时，该a的class变成n，其他大的ul下面的a的class变成m，小的ul里面的a标签不会变化。我这样子写，当我点击大的ul下面的a标签时，小ul里面的a标签也会变化。清帮我改一下上面的代码。
