Question

我在下面的代码中找到了我正在使用HTML，CSS和JavaScript创建的手风琴列表。我只是想知道为什么链接在我将它们放入手风琴列表后不起作用？我看不出我做错了什么。任何事都有帮助，欢呼。

Answer 1

这些行将事件侦听器绑定到包含.accordion元素，该元素会在任何内部单击时阻止默认操作：

var accordion = $('.accordion');
accordion.addEventListener("click",function(e) {
    e.stopPropagation();
    e.preventDefault();
    ...
}

如果您将其绑定到.accordionTitle，或者在类检查后将它们进一步向下移动（因此您只阻止传播并防止默认（如果它是您想要的元素），则链接可以正常工作。
