Angular 2单击+ ngClass,如何仅应用于SELF而不是ALLF中的所有元素

Question

在Angular 1.x中,以下代码可以正常工作,因为我想在ng-repeat中单击并翻转一张卡片

<div class="card" ng-repeat="let card of cards">
<div class="flipcard" ng-class="{'flipped':isflipped}" ng-click="isflipped = !isflipped">
</div>
</div>

但是在Angular 2中单击时,它会翻转ngFor循环中的每个"卡片"...如何仅将ngClass条件绑定到元素本身？

<div class="card" *ngFor="let card of cards">
<div class="flipcard"  [ngClass]="{'flipped': isflipped }" (click)="isflipped = !isflipped;">
</div>
</div>

Answer 1

将其更改为:

<div class="card" *ngFor="let card of cards">
    <div class="flipcard"  [ngClass]="{'flipped': card.isflipped }" (click)="card.isflipped = !card.isflipped;">
    </div>
</div>
