javascript - 如何在下一次出现相同元素之前包装每个元素及其所有兄弟元素？

Question

我有一些类似于以下的标记:

<h3>A Heading</h3>
<p>Here is a paragraph.</p>

<ul>
  <li>First</li>
  <li>Second</li>
</ul>

<blockquote>Here's some other block-level element</blockquote>

<h3>The Wrapping Should Stop Before This Heading, but a Second One Should Begin</h3>
<ol>
  <li>First</li>
  <li>Second</li>
</ol>

<p>Notice the varying block-level elements? It probably doesn't make any difference.</p>

我想将每个 h3 和直到但不包括下一个 h3 的所有内容包装在一个 div 中。

结果应该是:

<div>
  <h3>A Heading</h3>
  <p>Here is a paragraph.</p>

  <ul>
    <li>First</li>
    <li>Second</li>
  </ul>

  <blockquote>Here's some other block-level element</blockquote>
</div>

<div>
  <h3>The Wrapping Should Stop Before This Heading, but a Second One Should Begin</h3>
  <ol>
    <li>First</li>
    <li>Second</li>
  </ol>

  <p>Notice the varying block-level elements? It probably doesn't make any difference.</p>
</div>

我发现类似的问题 this one .它结合使用了 .nextUntil() 和 .andSelf()(或 .addBack() 一旦我的编辑被批准)，但这会将 h3 和它们之间的内容包装在 separate div 中。

Answer 1

好像.wrapAll()是缺失的环节。

$('h3').nextUntil('h3').addBack().wrapAll('<div>');
