angularjs - Controller 中未定义 ng-model

Question

我正在使用 ionic 并且我有以下观点:

<ion-view hide-nav-bar="true" ng-controller="loginController" class="login-view">
  <ion-content class="padding">

    <div class="row row-center">
      <div class="col">

        <div id="logo"></div>

        <form>
          <div class="list">
            <label class="item item-input">
              <input type="text" placeholder="Membership No" ng-model="membershipNo">
            </label>
            <label class="item item-input">
              <input type="password" placeholder="Password" ng-model="password">
            </label>
          </div>

          <button class="button button-block button-positive button-login" ng-click="login()">
            Login
          </button>
        </form>

      </div>
    </div>

  </ion-content>
</ion-view>

还有我的 Controller :

app.controller('loginController', ['$scope', '$localstorage',
    function($scope, $localstorage) {

        $scope.membershipNo;
        $scope.password;

        $scope.login = function () {
            console.log("User logged in with membership no: " + $scope.membershipNo +
    "\n and password: " + $scope.password);
        }

    }
]);

我不明白的是，当我单击按钮时，登录功能被正确调用。另外，如果在 Controller 中我去设置 $scope.membershipNo到“香蕉煎饼”之类的东西， View 实际上会更新。

然而，当登录功能实际运行时，会说membershipNo 和password 是未定义的。我对 Angular 和 Ionic 还很陌生，所以我知道这可能是一些 n00b 错误......

我最近遇到了完全相同的问题，这可能是一个解决方案:

修改后的报价:

"If you use ng-model, you have to have a dot in there."
Make your model point to an object.property and you'll be good to go.

Controller

$scope.formData = {};
$scope.login = function () {
  console.log("User logged in with membership no: " + $scope.formData.membershipNo +
  "\n and password: " + $scope.formData.password);
 }

Template

<input type="text" placeholder="Membership No" ng-model="formData.membershipNo">
<input type="password" placeholder="Password" ng-model="formData.password">
