Question

我尝试通过点击Details链接显示每张卡片的详细信息作为可折叠菜单。我使用了由id＆＃39;标识的bootstrap数据切换类。第

我无法在data-target动态中制作目标ID。我试过给data-target="openPanel[item]" /`data-target =＆＃34; openPanel [i1]＆＃34;＆＃39;获得动态值，但它不起作用。

Answer 1

使用*ngIf作为详细信息面板：

<div class="collapse" id="openPanel" *ngIf="isActive[i1]">
    This is {{item.year}} panel 
</div>

Answer 2

<div data-toggle="collapse" [attr.data-target]="'#openPanel_'+i1" class="row display-inline-mode">
              <h4   [ngClass]="{'flipped': isActive[i1] }" (click)="isActive=[];isActive[i1] = !isActive[i1];">Details
             </h4>&nbsp;&nbsp;&nbsp;
  </div>
<div class="collapse" id="openPanel_{{i1}}">
       This is {{item.year}} panel
      </div>

属性绑定是解决方案。 Bootstrap数据切换应该获得唯一ID，因此在您的情况下给出索引i1以使ID唯一参考：Angular 2 data attributes

Answer 3

将模板更改为：

<div class="border-box" id="panels">
    <div  class="quarter-panel panel" *ngFor="let item of quarterDataList;let i1 = index">
      <h2>{{item.year}}</h2>
      <div class="item-hover" *ngFor="let count of item.quarterData;let i = index" (click)="setClickedRow((i+'_'+item.year))" [class.active]="((i+'_'+item.year)) == selectedRow">
        <br>
       {{count.view}}-{{count.count}}
    </div>

         <div data-parent="#panels" data-toggle="collapse" [attr.data-target]="'#openPanel'+ i1" class="row display-inline-mode">
                <h4   [ngClass]="{'flipped': isActive[i1] }" (click)="isActive=[];isActive[i1] = !isActive[i1];">Details
               </h4>&nbsp;&nbsp;&nbsp;
         </div>
         <div class="collapse" id="openPanel{{i1}}">
            This is {{item.year}} panel
           </div>
</div>
