代替问号的是什么？这个问题的一般版本是：如何在单击元素的正下方选择一个非子缩进元素？

我最好的尝试是：

<ul id="thing_list">
        <li><div class="thing"><span>Thing 1</span></div></li>
            <div class="properties">
                <ol class="settings">
                    <li><span>Setting 1</span></li>
                        <div class="setting_explain">
                            <p class="explanation"><span>Explanation 1</span></p>
                        </div>
                    <li><span>Setting 2</span></li>
                        <div class="setting_explain">
                            <p class="explanation"><span>Explanation 2</span></p>
                        </div>

这显然不起作用，因为它总是只切换列表中的第一个p.explanation，而不是直接位于list元素本身下面的第一个p.explanation。

Answer 1

试试这个

$('ol.settings li').click(function(e) {
    $(this).siblings('.setting_explain').find('p.explanation').toggle();
  });

Answer 2

您的HTML标记无效，div.setting_explain应位于li下。请检查以下代码段。

$('ol.settings li').click(function(e) {
  $(this).find('p.explanation').toggle();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="thing_list">
  <li>
    <div class="thing"><span>Thing 1</span></div>
    <div class="properties">
      <ol class="settings">
        <li><span>Setting 1</span>
          <div class="setting_explain">
            <p class="explanation"><span>Explanation</span></p>
          </div>
        </li>

        <li><span>Setting 2</span>
        <div class="setting_explain">
            <p class="explanation"><span>Explanation</span></p>
          </div>
        </li>
      </ol>
    </div>
  </li>
</ul>

Answer 3

你为什么选择父母？

$('ol.settings li').click(function(e) {
  $(this).children('.explanation').toggle();
});
