Question

评论有三个层次。祖父母（深度-1）评论全部显示。我想向每个祖父母评论显示前两个深度2回复（父类评论），并让其余部分隐藏并显示切换按钮（理想情况下，在“隐藏”和“显示”之间更改文本）。除非只有一个深度为2的回复，否则深度为3的回复都应该被隐藏，如果可能的话，应该显示第一个深度为3的回复，以便在所有场景中显示总共两个回复。

我设法在fiddle

中切换所有深度3回复

这是标记和javascript（更新）：

<div id="comments">
  <ol class="commentlist">
    <li class="comment byuser comment-author-admin even thread-even depth-1" id="li-comment-677">
      <div id="comment-677" class="grandparent">

Answer 1

你基本上和第三级做的一样，但使用gt()（从零开始）选择器跳过前两个回复：

http://jsfiddle.net/isherwood/Frpmj/3

$(this).next('ul').find('li:gt(1)').slideToggle();

jQuery显示前两个回复，隐藏其余部分
