Angular JS ng-重復
[英]Angular JS ng-repeat
問題描述
我正在開發類似tinder的應用程序，成功創建了向左滑動和向右滑動的效果，我在此處使用ng-repeat，但我希望在所有卡交換一次之前，該卡不應該重復。
這是我的代碼：-

我認為您應該為所有對象添加一個屬性，如swaped因此當您滑動時，您只需要做card.swaped = true; 並在您的ng-repeat濾card.swaped == true
<swipe-card ng-repeat="card in cards | filter:swaped:false" on-swipe="cardSwiped($index)">
Angular js中的ng-repeat
