Question

在我目前的示例中，您会看到＆＃39;。崩溃＆＃39;当有人点击div本身的任何地方时触发的容器。有许多＆＃39; 崩溃＆＃39; divs 但是每个人都是单独触发的，因为这个＆＃39;在JS中。问题是我不希望整个容器成为触发器。

如何更换＆＃39; .collapse＆＃39;在JS中使用h2：取而代之但仍然触发.collapse为＆＃39;这个＆＃39;

让我知道这是否令人困惑所以我可以编辑我的问题以使其更容易理解。

HTML

<div class="collapse">
<h2>sometext
::after
</h2>
</div>

JS

$('.collapse').on('click',function(e){
  e.preventDefault();
  $(this).toggleClass('active');
});

我在代码中看不到任何h6，但您可以使用h2并使用$(this)和parent()来选择它的父母。我希望这是你正在寻找的东西：

＆＃13;

$('h2').on('click', function(e) {
  $(this).parent().toggleClass('active');
});
