jQuery+；canJS：单击嵌套列表以进行多次传播

我正在使用CanJS1.1.8和jQuery

我有一个与一些德国州的嵌套列表

<ul>
<li class="states active">
    <i class="icon-screenshot"></i> <span style="background-color: rgb(255, 255, 255); padding-right: 79px;">Bundesland</span>

如果单击.states，将显示隐藏列表。但是，如果我单击嵌套列表中的一个复选框，列表也会崩溃。 我怎样才能防止这种情况

嵌套列表是绝对定位的

这是小提琴

尝试更具体的选择器：

'li.states click': function (el, e) {

---

您有一些我们可以看到的实时代码吗？

我认为您的问题与事件冒泡有关。若您单击

.states

列表的子级，则会弹出列表，并触发事件处理程序代码。您需要查看事件上的

e.target

对象——aka，触发事件的元素，不一定是注册事件的元素——并且只处理目标具有

.states

类的情况

'.states click' : function(el, e) {

    if ( !$(e.target).hasClass('.states') ) return false;

    // your handler code here

}

'.states click' : function(el, e) {

    if ( !$(e.target).hasClass('.states') ) return false;

    // your handler code here

}
