我正在尝试做的是复制一个手风琴式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();
});
虽然是active.siblings（）。not（active）.removeClass（'active'）; 无法正常工作我基本上希望它选择所有同级UL标签以及同级的所有子级UL标签，但不包括“活动/当前”选择。
我已将此提琴设置为示例http://jsfiddle.net/7u3pw1hz/
问题是，其他ul元素不是同级元素，它们是li当前同级元素的子元素li
$('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;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
