展开和关闭手风琴引导程序

Question

您好，我在手风琴方面遇到了麻烦，这是我的代码，请照亮我！

    <div id="tg-accordion" class="tg-accordion">
   <div class="tg-panel">
      <h4 class="active">Why is accreditation important</h4>
      <div class="tg-panelcontent" style="display: block;">
         <div class="tg-jobdescription">
            <div class="tg-description">
              <p>description</p>
            </div>
         </div>
      </div>
   </div>
   <div class="tg-panel">
      <h4 style="margin-bottom: 10px!important;">European Regulation 765/ 2008</h4>
      <div class="tg-panelcontent" style="display: none;">
         <div class="tg-jobdescription">
            <div class="tg-description" style="margin-bottom: 10px!important;">
               <p>description</p>
         </div>
      </div>
   </div>
   <div class="tg-panel">
      <h4>Recognition of certifications. How accreditation provides recognition</h4>
      <div class="tg-panelcontent" style="display: none;">
         <div class="tg-jobdescription">
            <div class="tg-description">
              <p>description</p>
            </div>
         </div>
      </div>
   </div> 

这是html，当我第二次单击以关闭该Accordeon选项卡并且打开它以在tg-panel背景上显示为蓝色时，我想要一些jquery。 这是我的Jquery：

        $(function() {
            $('.tg-panelcontent').hide();
            // $('#tg-accordion h4:first').addClass('active').next().slideDown('slow');
            $('#tg-accordion h4').click(function() {
                if($(this).next().is(':hidden')) {
                    $('#tg-accordion h4').removeClass('active').next().slideUp('slow');
                    $(this).toggleClass('active').next().slideDown('slow');
                }
            });
        }); 

Answer 1

如果您已经包含了Bootstrap的脚本，则不需要其他脚本即可执行所需的行为。 查看此示例，该示例可在Bootstrap的官方页面上找到 。

这样， <a>或<button>标记处的data-toggle属性指示该元素是“折叠切换器”，并且href / data-target指向元素ID，该元素ID是要折叠/展开的容器。 简单:)

<p>
  <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
    Link with href
  </a>
  <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
    Button with data-target
  </button>
</p>
<div class="collapse" id="collapseExample">
  <div class="card card-body">
    Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
  </div>
</div>

你什么都不需要 仅确保指向CSS的链接位于页面的顶部，并且脚本和页面的末尾。 它应该工作正常。

 <!-- CSS needed at the beginning of the page --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous"> <div class="accordion" id="accordionExample"> <div class="card"> <div class="card-header" id="headingOne"> <h5 class="mb-0"> <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne"> Why is accreditation important </button> </h5> </div> <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample"> <div class="card-body"> description </div> </div> </div> <div class="card"> <div class="card-header" id="headingTwo"> <h5 class="mb-0"> <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo"> European Regulation 765/ 2008 </button> </h5> </div> <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample"> <div class="card-body"> description </div> </div> </div> <div class="card"> <div class="card-header" id="headingThree"> <h5 class="mb-0"> <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseThree" aria-expanded="false" aria-controls="collapseThree"> Recognition of certifications.

您可以简单地在标头上添加data-toggle="collapse"以及data-target="#idOfYourElement"来触发折叠。 并将display:none替换为目标元素上的collapse类：

工作实例：
