所以我有这个问题。

我想知道如何添加课程＆＃34;选择＆＃34; 在仅使用类album_reviews的部分中，对于称为recensie的每个奇数类。

<section class="album_reviews">
    <h2 class="sectiontitel"> Album Reviews </h2>
    <article class="recensie">
      <h1> Neil Young – A Letter Home </h1>
      <img src="Images/Albums/A_Letter_Home.jpg" alt="album_image"/>
      <p>Earlier this year, Neil Young unveiled Pono, a super-high-def audio service meant to deliver us from the sonic crimes of the earbud era.

  </section>

那是我的HTML代码。我知道如何只将类添加到奇数中但不仅仅是在section中的几率.album_reviews

希望有人可以提供帮助

Answer 1

像这样：

$('.album_reviews .recensie:odd').addClass('selected');

Answer 2

在jquery中使用:odd选择器。它选择所有奇数元素

$("section.album_reviews .recensie:odd").addClass('selected');

Answer 3

$('.album_reviews').find('.recensie:odd').addClass('selected');

如何在类'album_revieuws'的部分中将类添加到奇数类“recensie”
