javascript - jQuery 选择除自己以外的所有 sibling 和 child

Question

我想做的是复制一个 Accordion 类型的 jQuery 小部件

我有以下代码:

$('a').on('click', function (e) {
  var active = $(this).parent().next();
  active.toggleClass('active');
  active.siblings().not(active).removeClass('active');
  e.preventDefault();
});

尽管 active.siblings().not(active).removeClass('active');不起作用 我希望它如何做 我基本上希望它选择所有 sibling 的 UL 标签和 sibling 的任何子 UL 标签，但排除事件/当前选择。

我已将此 fiddle 设置为示例 http://jsfiddle.net/7u3pw1hz/

Answer 1

问题是，其他 ul 元素不是兄弟，它们是当前 li 的兄弟 li 元素的子元素

$('a').on('click', function(e) {
  var active = $(this).parent().next();
  active.toggleClass('active');
  active.parent().siblings().children('ul').removeClass('active');
  active.find('ul').removeClass('active');
  e.preventDefault();
});

ul ul.active {
  max-height: 800px;
}
ul ul {
  max-height: 0;
  overflow: hidden;
}
