我很难在过去几个小时内弄错...我使用自举手风琴和把手模板引擎 - 它可以正常使用我的数据库值。
问题是，当您第一次加载页面时，所有选项卡都打开...当我关闭并重新打开其中一个时，它们都会关闭。这是页面代码：
<div class="panel-group" style="margin: 1%" id="accordion" role="tablist" aria-multiselectable="true">
{{# each questions }}
<div class="panel panel-primary">
<div class="panel-heading" role="tab" id="{{@index}}">
<h4 class="panel-title">
<a role="button" data-toggle="collapse" data-parent="#accordion" href="#{{ this.id }}" aria-expanded="true" aria-controls="{{ this.id }}">
{{ this.syntax }}
</a>
</h4>
</div>
<div id="{{ this.id }}" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="{{@index}}">
<div class="panel-body">
{{ this.answer }}
</div>
</div>
</div>
{{/each}}
</div>
我使用把手，所以这里是布局：

<li><a href="/questions">Questions</a></li>
<li class="right"><a href="#about">About</a></li>
</ul>
{{{ body }}}
</body>
</html>
我尝试关注此堆栈case，所以我将此代码添加到我的js文件中，但它不会帮助..
$(function() {
var transition = false;
var $active = true;
$('.panel-title > a').click(function(e) {
e.preventDefault();
});
$('#accordion').on('show.bs.collapse',function(){
if($active){
$('#accordion .in').collapse('hide');
}
});
$('#accordion').on('hidden.bs.collapse',function(){
if(transition){
transition = false;
$('.panel-collapse').collapse('show');
}
});
});

尝试仅将.collapse类添加到html中的相应元素。
此外，您不需要处理节目和隐藏事件。

面临同样的问题 - 所有部分都在.collapse调用上打开。 +另一个有趣的错误（下面）。
但是找到了解决方案。
我有正确的HTML标记（并且工作正常），一开始没有JS。但后来我想以编程方式切换部分。当我在某个部分调用.collapse（＆＃39; show＆＃39;）时 - 其他部分显示为不同步（某些部分保持打开状态），即使是手动点击也是如此。这里的技巧是使用.collapse（）调用强制初始化插件。所以以避免扩展所有部分（并使其可编程地控制而没有任何问题）您必须提供两个选项，如下所示：
$acc.find('.collapse').collapse({
parent: $acc, // to make it work as accordion
toggle: false // don't toggle while initialising
});
查看代码段了解更多详情。
我希望它有所帮助
$(function(){
var tabIndex = 0;
var $acc = $('#accordion');
const tabsCount = $acc.find('.collapse').length;
// IF SKIP JS INITIALISATION - SHOW METHOD WILL NOT CLOSE OTHER TABS (UNLESS THEY'RE ALREADY INITIALIZED WITH MANUAL CLICKS)
$acc.find('.collapse').collapse({
parent: $acc, // to make it work as accordion
toggle: false // don't toggle while initializing
});
$('#openNextTabBtn').on('click', function(){
$acc.find('.collapse').eq(++tabIndex % tabsCount).collapse('show');
});
