如何获得具有等级的成分的补贴
原标题:how do i get an id of an element which has a class

请允许我说,我有名单。

<ul id="left-side-menu" style="display: block;">

    <li> <a id="1" class="lists active" href="javascript:void(0)">My company 1</a></li>

    <li> <a id="2" class="lists" href="javascript:void(0)">My company 2</a></li>

    <li> <a id="3" class="lists" href="javascript:void(0)">My company 3</a></li>
</ul>

为了获得使用清单类别积极分类的成分的补贴,我写道:

(美元)

但它有错误。

美元(“a.lists”)。 缩略语

请帮助我

最佳回答
$("a.lists.active").attr( id )
问题回答
$("a.lists.active").attr( id );
