如何防止手风琴关闭内容选择？

Question

我的JS有问题，点击内容如何防止手风琴关闭

您可以在下面找到我的代码；代码工作正常；唯一的问题是当我 select 内容“下拉列表”中的任何内容时，手风琴关闭。如果我点击它，我需要手风琴保持打开状态。

我希望这是有道理的。

非常感谢任何帮助

    const accordion = document.getElementsByClassName ('media-box-actuaries_accordion');

for (i = 0; i<accordion.length; i++ ){
  accordion[i].addEventListener('click', function(){
    this.classList.toggle('active');

  })
}

.media-box-actuaries_accordion {
  position: relative;
  margin-bottom: 20px;
  text-decoration: none;
}

.media-box-actuaries_accordion {
  position: relative;
  margin-bottom: 20px;

}
.media-box-actuaries_accordion_content {

  overflow: hidden;
  display: none;
  overflow-y: auto;
  transition: all 0.5s ease-out;
}

.media-box-actuaries_accordion.active .media-box-actuaries_accordion_content {

Answer 1

你是这个意思吗？ Reproduce repo

const accordion = document.getElementsByClassName ('media-box-header-accordion');

for (i = 0; i<accordion.length; i++ ){
  accordion[i].addEventListener('click', function(){
    this.parentNode.classList.toggle('active');

  })
}

Answer 2

您的问题是由所谓的 event bubbling.

引起的

一个解决方案是将切换 active class 的事件侦听器附加到手风琴的 header 元素（具有 class [=12= 的元素]), 像这样:

const accordions = document.getElementsByClassName("media-box-actuaries_accordion");

for (i = 0; i < accordions.length; i++) {
    const accordion = accordions[i];
    const header = accordion.querySelector(".media-box-header-accordion");

    header.addEventListener("click", function () {
        accordion.classList.toggle("active");
    });
}
