javascript - 通过验证将 Angular 形式输入到数组

Question

在 Angular JS 中是否有一种方法可以将管理器列表(或任何项目)推送到数组并在 Angular.js 中进行验证。我基本上想创建一个数组作为 ng-model 并仍然验证它。这是可以做到的还是我的做法是错误的？

    var app = angular.module("FormTest",[]);
    app.controller("AppCtrl",  ["$scope", function($scope){

        var appCtrl = this;
        appCtrl.appName = "Form Array";
        $scope.managers = [""];
        $scope.form = {};
        $scope.form.managers = $scope.managers;

        $scope.addManager = function(){

            $scope.managers.push('');
        }

        $scope.removeManager = function(index){

            if($scope.managers.length > 1){

                $scope.managers.splice(index, 1);

            }
        }

    }])

    angular.element(document).ready(function(){
        angular.bootstrap(document.querySelector('html'), ["FormTest"]);
    })

                <div class="btn btn-primary" ng-click="addManager()">add manager</div>

        </div>
        <form novalidate name="form">

                        <div class="btn btn-default">
                            <span class="glyphicon glyphicon-remove-circle" ng-click="removeManager($index)"></span>
                        </div>
                    </div>
                </div>
            </div>

        </form>
    </div>

在您的示例中，好吧，除了正则表达式。

看示例代码jsfiddle .

<h2>{{app.appName}}</h2>
<div>
  {{form.managers}}
  <div>
    <div>{{managers}}</div>
    <button class="btn btn-primary" ng-click="addManager()">add manager</button>
  </div>
</div>
<form novalidate name="form">
  Form valid={{form.$valid|json}}
  <div class="form-group" ng-repeat="item in managers track by $index">
    <div class="row-fluid">
      <div class="col-md-5">
        <input type="text" ng-model="managers[$index]" name="manager{{$index}}" ng-pattern="/^\w{3,}$/" required class="form-control">
        {{form['manager'+$index].$error}}
      </div>
      <div class="col-md-1">
        <div class="btn btn-default">
          <button class="glyphicon glyphicon-remove-circle" ng-click="removeManager($index)">Remove</button>
        </div>
      </div>
    </div>
  </div>

</form>
