代表小组标题点击内部 link 以获得 bootstrap 手风琴

Question

我有一个 bootstap 面板手风琴：

<div class="modal-body">
   <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
      <div class="panel panel-default">
         <div class="panel-heading" role="tab" id="headingOne">
            <h4 class="panel-title">
               <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne" class="collapsed">
               Annual </a>
            </h4>
         </div>
         <div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne" aria-expanded="false" style="height: 0px;">
            <div class="panel-body"></div>
         </div>
      </div>
      <div class="panel panel-default">
         <div class="panel-heading" role="tab" id="headingTwo">
            <h4 class="panel-title">
               <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
               Semi-Annual </a>
            </h4>
         </div>
         <div id="collapseTwo" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingTwo" aria-expanded="false" style="height: 0px;">
            <div class="panel-body"></div>
         </div>
      </div>
   </div>
</div>

而不是单击微小的 <a> link，我希望整个 .panel-heading 触发内部 <a>.

的单击

由于明显的 Maximum call stack size exceeded 错误，我无法使用以下代码：

panelHeadings.on('click', function (e) {
    $(this).find('a').click(); // trigger('click') behaves the same
    e.stopPropagation();
    e.preventDefault();
    return false;
});

...但是使用答案中的代码导致我单击时没有任何反应：

panelHeadings.on('click', function (e) {
    $(this).find('a').triggerHandler('click');
    e.stopPropagation();
    e.preventDefault();
});

还有其他方法可以触发内a的点击事件吗？

这是一种方法 - 使用 BS-collapse-toggle:

为锚标记阻止了默认事件，并向 panel-heading 添加了一个新事件：

$('div#accordion .panel-heading a[data-toggle="collapse"]').on('click', function (e) {
  e.preventDefault();
});

$('div#accordion .panel-heading').on('click', function() {
  $(this).parent().find('.collapse').collapse('toggle');
});

$('div#accordion .panel-heading a[data-toggle="collapse"]').on('click', function (e) {
 e.preventDefault();
});

$('div#accordion .panel-heading').on('click', function() {
 $(this).parent().find('.collapse').collapse('toggle');
});

div#accordion .panel-heading {
  cursor: pointer;
}

   </div>
