【问题描述】：

当按下正常的引导按钮时如何使面板折叠？这是我的代码：

<div class="panel panel-primary" style="border-color: #464646;">
    <div class="panel-heading" style="border-color: #BBBBBB; height: 35px; padding-top: 3px;">
        <div style="float: left; margin-top: 5px;" data-toggle="collapse" href="#collapse1">Select Object</div>
    </div>
    <div id="collapse1" class="panel-collapse collapse">
        <div class="panel-body">
            <!--Object Buttons-->
            <button *ngFor="let object of objects" type="button" data-toggle="collapse" style="margin-right: 10px;" class="btn btn-primary" (click)="doThings();"</button>
        </div>
    </div>
</div>

单击panel-heading 时panel-body 将折叠，但我希望单击“对象”按钮之一时面板主体折叠。

【解决方案1】：

您可以将相同的data-target="#collapse1" 应用到按钮上，就像 href 一样。

href

<a data-toggle="collapse" href="#collapse1">Select Object</a>

按钮

<button class="btn btn-danger" type="button" data-toggle="collapse" data-target="#collapse1">

另外，您的按钮没有关闭。缺少> 来关闭它。

<button *ngFor="let object of objects" type="button" data-toggle="collapse" style="margin-right: 10px;" class="btn btn-primary" (click)="doThings();"

示例：

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="panel-group">
  <div class="panel panel-primary">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a data-toggle="collapse" href="#collapse1">Select Object</a>
      </h4>
    </div>
    <div id="collapse1" class="panel-collapse collapse">
      <div class="panel-body">
        <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapse1">
          Button with the same data-target
        </button> Panel Body
      </div>
    </div>
  </div>
  <div class="panel panel-danger">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a data-toggle="collapse" href="#collapse2">Select Object</a>
      </h4>
    </div>
    <div id="collapse2" class="panel-collapse collapse">
      <div class="panel-body">
        <button class="btn btn-danger" type="button" data-toggle="collapse" data-target="#collapse2">
          Button with the same data-target
        </button> Panel Body
      </div>
    </div>
  </div>
