javascript - Angular ng 消息在 ng 重复表单上显示错误

Question

我想用 ng repeat 生成输入，问题是当我有一个错误时，这只适用于最后一个元素，我怎样才能使它适用于每个元素？

<form name="setPlayersForm">
  <div ng-repeat="player in rp.KillerService.getPlayers() track by $index" class="name-input">
    <input type="text"
           placeholder="Your Name"
           ng-model="player.name"
           required/>
    <a class="fa fa-trash-o" ng-if="player.newPlayer" ng-click="rp.removePlayer(player)"></a>
  </div>
  <ng-messages for="setPlayersForm.$error" ng-if="rp.submitted">
    <ng-message when="required" class="alert-box alert">This field is required</ng-message>
  </ng-messages>
</form>

我不知道我是否理解你的问题，但我使用这种方法来处理 ng-repeat 中的输入。考虑以下代码

<form name="sampleForm" novalidate>
    <div ng-repeat="item in items">
        <input type="text" name="name{{$index}}" required ng-model="item.name">
        <div ng-messages="sampleForm['name'+$index].$error">
            <div ng-message="required" class="error">This field is required</div>
        </div>

        <input type="text" name="price{{$index}}" required ng-model="item.price">
        <div ng-messages="sampleForm['price'+$index].$error">
            <div ng-message="required" class="error">This field is required</div>
        </div>
    </div>
</form>

只需遵循代码。有什么不明白的就在下面评论吧
