jQuery，ID中类的选择器 [英] jquery, selector for class within id

问题描述

下面，我该如何选择包含id = "my_id"的元素中包含类my_class的元素?

Below, how should I select the elements that contain the class my_class within the element with id = "my_id"?

请注意，该元素可能还具有另一个类，我没有为此选择.

Note that the element may also have another class, which I am not selecting for.

<div id = "my_id">
    <span class = "my_class hidden">hi</span>
    <span class = "my_class">hello</span>
</div>

正在尝试

$("#my_id [class*=my_class ]")

推荐答案

您可以将类选择器与后代选择器

$("#my_id .my_class")
