Question

I have an HTML structure lik3

<div>
  <ul>
    <li>
      <div>Other elements</div>
        <div>
          <ul>
            <li class='base-parent parent'>
              <div>Base Parent DEFINED</div>
              <ul>
                <li class="parent parent-level-1">
                  <div class="child">Inner Parent Level 1</div>
                  <ul>
                    <li class="parent parent-level-2">
                      <div class="child">Inner Parent Level 2</div>
                      <ul>
                        <li class="parent parent-level-3">
                          <div class="child">Innermost child 1</div>
                        </li>
                        <li class="parent parent-level-3">
                          <div class="child">Innermost child 2</div>
                        </li>
                      </ul>
                    </li>
                  </ul>
                </li>
              </ul>
            </li>
          </ul>
        </div>
      </li>
    </ul>
  </div>

Though I can find the closest parent LI of div.child, I need to know how I can find the first parent LI element of class div.child under li.base-parent excluding base-parent.

Answer 1

你可以很容易地使用parents()：

$('.child').parents('li.parent:not(.base-parent)').last();

这是一个jsFiddle。

Answer 2

似乎有不合理的 div 数量。你听说过身份证吗？

那么任务就简单多了。

IE

$('#myide').whatever();
