将类添加到父元素 [英] Add class to parent element

问题描述

我知道这个问题之前已经被问过很多次了，但我找不到任何有效的工具。
我需要将一个类添加到通过我的ul自动生成的div。

I know this has been asked many times before, but I could not find anything that worked. I will need to add a class to a div that gets autogenerated over my ul.

这是我的html代码：

This is my html code:

<div class="wrapper">
    <ul id="bx-pager">
       <li><a><img></a></li>
       <li><a><img></a></li>
    </ul>
</div>

我需要为div classwrapper添加第二个类，但在尝试过之后，我不能让它工作。如果有人能够帮助我完成这个简单的任务，我会很高兴，但是告诉我如何去做。我对jQuery没有多少经验，但现在需要它。

I need to add a second class to div class "wrapper", but after what I have tried I can't get it to work. I would be nice if someone can help me out with this simple task, but showing me how to do it. I don't have much experience with jQuery, but need it now.

推荐答案

您可以使用JQuery

You can use the JQuery parent selector:

$('#bx-pager').parent('div').addClass('newClass');
