ng-model在控制器中未定义 [英] ng-model is undefined in controller

问题描述

我正在使用离子，我有以下观点：

I'm using ionic and I have the following view:

<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>

我的控制器：

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，当我点击按钮时，正确调用登录功能。此外，如果在控制器中我将 $ scope.membershipNo 设置为类似Banana Pancake的内容，视图实际上会更新。

What I don't understand, is that when I click the button, the login function is called correctly. Also, if in the controller I go and set $scope.membershipNo to something like "Banana Pancake", the view actually updates.

然而，当登录功能实际运行时，会说memberNo和密码未定义。我对Angular和Ionic很新，所以我知道这可能是一些n00b的错误......

Yet when the login function actually runs, is says that membershipNo and password are undefined. I'm fairly new to Angular and Ionic so I know this is probably some n00b mistake...

I had exact the same issue recently and that's probably a solution: https://stackoverflow.com/a/22768720/552936

修改后的报价：

如果你使用ng-model ，你必须有一个点。
让你的模型指向 object.property ，你会很高兴。

控制器

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

模板

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