动态创建时引导崩溃不起作用

Question

我正在通过 ajax 调用获取我的内容并在运行时创建所有可折叠面板。 但是切换功能不能以这种方式工作。我正在使用骨干木偶集合和项目视图来创建我的面板组。

我检查了静态内容，它适用于静态数据。

我检查了几个链接，但在我的情况下似乎没有任何效果。

How to make Twitter Bootstrap Collapse work on dynamically loaded html using ajax

https://github.com/twbs/bootstrap/issues/2274

这是我的 html 的样子：

<div id="accordion" class="panel-group">
    <div class="panel panel-default">
        <div class="panel-heading">
            <ul class="home_nav" data-toggle="collapse" data-parent="#accordion"
                data-target="NewsMaintenanceMenu">
                ...
            </ul>
            <span class=""><i class="glyphicon glyphicon-chevron-right"></i></span>
        </div>
        <div id="NewsMaintenanceMenu" class="panel-collapse collapse">
            <div class="panel-body">
                <table class="table table-striped">
                    <tbody>
                        ....
                    </tbody>
                </table>
            </div>
        </div>
    </div>
</div>

Answer 1

我暂时用过jQuery。

   $(".panel").on("click", function(e){
              var $_target =  $(e.currentTarget);
              var $_panelBody = $_target.find(".panel-collapse");
              if($_panelBody){
                $_panelBody.collapse('toggle')
              }
        })

Answer 2

实现此目的的另一种方法...

function collapseOnClick(collapseTrigger){
    /**
   * Manually add collapse on click event.
   * 
   * Because dynamically added Bootstrap collapse elements don't
   * work automatically for me most of the time.
   * 
   * 'data-target' is a selector for the collapsing element as per
   * the Bootstrap documentation. 
   * https://getbootstrap.com/docs/4.3/components/collapse/#via-data-attributes
   *
   * @param {jQuery} collapseTrigger Trigger element for the collapse.
   * 
   */ 
    var target = collapseTrigger.attr("data-target")
    collapseTrigger.on('click',function(){
        $(target).collapse('toggle')
    })
}

Answer 3

在新创建的面板上调用 .collapse() 来获取 ajax 成功。如果不知道怎么做，请提供代码sn-p。
