按钮上的折叠面板单击 - 引导程序

Question

按正常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-body时panel-heading会崩溃，但我希望在单击其中一个'对象'按钮时让面板体折叠。

您可以将相同的data-target="#collapse1"应用于href所具有的按钮。

<强> 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">

此外，您的按钮尚未关闭。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();"
