目标父div Jquery

Question

我有这段代码：

＆＃13;

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="view-poke">
	<div class="content">
		<div class="field"><a href="" class="active"></a></div>
	</div>
</div>

＆＃13;

＆＃13;

＆＃13;

我想在.view-poke有课程<a></a>时将课程添加到.active

Answer 1

循环浏览每个a.active课程，并将自定义class添加到其parent

＆＃13;

＆＃13;

$(function() {
  $('a.active').each(function() {
    $(this).closest('.view-poke').addClass('customClass')
  })
})

＆＃13;

.customClass {
  background-color: orange;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="view-poke">
  <div class="content">
    <div class="field"><a href="" class="active">Anchor 1</a>
    </div>
  </div>
</div>
<div class="view-poke">
  <div class="content">
    <div class="field"><a href="">Anchor 2</a>
    </div>
  </div>
</div>
<div class="view-poke">
  <div class="content">
    <div class="field"><a href="" class="active">Anchor 3</a>
    </div>
  </div>
</div>
<div class="view-poke">
  <div class="content">
    <div class="field">
      <a href=""></a>Anchor 4</div>
  </div>
</div>

＆＃13;

这可能是你在寻找

$('a.active').each(function() {
    $(this).parent().parent().addClass('.view-poke');
});
