Question

我有以下手风琴列表，使用ng repeat来填充页面中包含来自数据库的数据，当页面加载时，手风琴就在那里并且里面有数据但是如果我点击一个随机的第一个关闭，只有第一个可以打开和关闭。

<div class="bs-example">
    <div class="panel-group" id="accordion" *ngFor="let message of messages">
        <div class="panel panel-default" >
            <div class="panel-heading">
                <h4 class="panel-title">
                    <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">data
                </h4>
            </div>
            <div id="collapseOne" class="panel-collapse collapse in">
                <div class="panel-body">
                 data
                </div>
            </div>
        </div>
    </div>
</div>

我认为这导致了同样的问题。尝试为index

添加id

<div class="bs-example">
    <div class="panel-group" [attr.id]="'accordion_' + i" *ngFor="let message of messages; let i = index;">
        <div class="panel panel-default" >
            <div class="panel-heading">
                <h4 class="panel-title">
                    <a data-toggle="collapse" [attr.data-parent]="'#accordion_' + i" [attr.href]="'#collapseOne_' + i">{{ message.firstName }} {{ message.lastName }}</a>
                </h4>
            </div>
            <div [attr.id]="'collapseOne_' + i" class="panel-collapse collapse in">
                <div class="panel-body">
                  details here {{ message.empId }}
                </div>
            </div>
        </div>
    </div>
</div>
