Angular 2单击+ ngClass，如何仅应用于SELF而不是ALLF中的所有元素 [英] Angular 2 Click + ngClass, how to apply ONLY to SELF but not ALL elements inside ngFor

问题描述

在Angular 1.x
中，以下代码可用，因为我想在ng-repeat中点击并翻转一张卡

In Angular 1.x this following code works as I want to to click and flip a card inside an ng-repeat

<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
点击时，它会翻转ngFor循环中的每个卡 ...如何仅将ngClass条件绑定到元素本身？

However in Angular 2 when clicked, it flipped every "card" inside the ngFor loop... how do I bind the ngClass condition to the element itself only?

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

推荐答案

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>
