javascript - 单击标题时jQuery上下滑动ul

问题描述

对于我的页面，我的标题带有“head”类。当我单击它们时，它们应该在它们下面显示“内容”的 ul 类，并且当单击新标题时，当前显示的列表将消失，并出现新标题的新列表。我把它记下来了，但是说我单击标题 1 并显示列表一。当我再次单击它时，我需要将列表向后滑动，但我无法让它成为那样。这是我到目前为止所拥有的：

<!DOCTYPE html>

  <link href="styles/normalize.css" rel="stylesheet" />
  <link href="styles/my_style.css" rel="stylesheet" />
  <script>
  $(document).ready(function(){
    $(".head").on("click", function(){
      $(".content").hide();
      $(this).next(".content").slideToggle();
    })
  })
  </script>

</body>
</html>

当我单击同一个标题时，我需要帮助来获取它所在的标题列表以向上滑动。

解决方案

您只需要从您调用的选择中排除当前项目hide。该not方法适用于此。

$(document).ready(function() {
  $(".head").on("click", function() {
    let $list = $(this).next(".content");
    $(".content").not($list).hide();
    $list.slideToggle();
  })
})
.content {
  display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<h4 class="head">Mini Sprint</h4>
<ul class="content">
  <li>10/30/20<br>Memorial Park<br>Appleton</li>
</ul>
<h4 class="head">Iron Horse</h4>
<ul class="content">
  <li>11/06/20<br>Bay Beach Park<br>Green Bay</li>
</ul>
<h4 class="head">Twilight Trail</h4>
<ul class="content">
  <li>11/13/20<br>>River's Edge Park<br>Wrightstown</li>
</ul>
