Bootstrap 4手风琴切换全部

Question

我试图通过单击按钮来切换所有手风琴项目的状态。默认情况下，我希望它们全部关闭。按钮应该是Open All或Close All。

根据docs我应该能够使用toggle()方法？

我已将下面的当前代码包含在一个小提琴链接中。

HTML

<button id="toggleAccordions" class="btn btn-primary" type="button" data-toggle="collapse">Open / Close</button>

<div id="accordion" role="tablist">
  <div class="card">
    <div class="card-header" role="tab" id="headingOne">
      <h5 class="mb-0">
        <a data-toggle="collapse" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </a>
      </h5>
    </div>

    <div id="collapseOne" class="collapse" role="tabpanel" aria-labelledby="headingOne" data-parent="#accordion">
      <div class="card-body">

        </a>
      </h5>
    </div>
    <div id="collapseTwo" class="collapse" role="tabpanel" aria-labelledby="headingTwo" data-parent="#accordion">
      <div class="card-body">

  <div class="card">
    <div class="card-header" role="tab" id="headingThree">
      <h5 class="mb-0">
        <a class="collapsed" data-toggle="collapse" href="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
          Collapsible Group Item #3
        </a>
      </h5>
    </div>
    <div id="collapseThree" class="collapse" role="tabpanel" aria-labelledby="headingThree" data-parent="#accordion">

</div>

JQuery的

$(function() {
  $('#toggleAccordions').on('click', function(e) {
    $('#accordion .collapse').collapse('toggle')
  })
});

Fiddle。

任何帮助表示赞赏。

Answer 1

这不是您的代码的确切答案，而是一个解决方案的一般概念，对我使用Bootstrap 4手风琴。

手风琴是构建的，因此当时只能显示一个面板，所以诀窍是首先删除show上的data-parent属性并重新添加到hide上来覆盖此行为。

在这种情况下，我有两个按钮。一个用于表演，一个用于隐藏。

 $(function() {
    $('#toggleAccordions-show').on('click', function(e) {
        $('#accordion .collapse').removeAttr("data-parent");
        $('#accordion .collapse').collapse('show');
    })
    $('#toggleAccordions-hide').on('click', function(e) {
        $('#accordion .collapse').attr("data-parent","#accordion");
        $('#accordion .collapse').collapse('hide');
    })
});

Answer 2

你可以尝试下面的代码：

  $(function() {
  $('#toggleAccordions').on('click', function(e) {
    $('#accordion .collapse').toggleClass('show');
  })
});

Answer 3

基于Turbojohan的响应，它可以写得更短，以便您没有重复的jQuery选择器：

$(function() {
    $('#toggleAccordionShow').on('click', function(e) {
        $('#accordion .collapse').removeAttr("data-parent").collapse('show');
    });
    $('#toggleAccordionHide').on('click', function(e) {
        $('#accordion .collapse').attr("data-parent","#accordion").collapse('hide');
    });
});
