Angularjs 角度，角度火力-在控制器中获取值

我正在制作web应用程序，从输入文本中获取值时遇到问题。如何从输入中获取它们

var app = angular.module('app', ['ngRoute', 'firebase']);

app.controller("AuthCtrl", function($scope, $firebaseObject) {
   var ref = firebase.database().ref();
   $scope.data = $firebaseObject(ref);
});

app.controller("AuthCtrl", ["$scope", "$firebaseAuth", 
function($scope, $firebaseAuth) {
  $scope.login = function($scope) {
    var login = '';
    var pass = '';

    $scope.authObj = $firebaseAuth();
    $scope.authObj.$signInWithEmailAndPassword(login, pass)
    .then(function(firebaseUser) {
        console.log("Signed in as:", firebaseUser.uid);
    }).catch(function(error) {
        console.error("Authentication failed:", error);
   });
  }
 }
]);

解决方案： 使用了错误的控制器。 从AuthCtrl到loginCtrl，一切正常！ 一切都是因为我在使用ngRoute

app.controller("logintCtrl", ["$scope", "$firebaseAuth", 
function($scope, $firebaseAuth) {
   $scope.login = function($scope) {
     var login = '';
     var pass = '';

    $scope.authObj = $firebaseAuth();
    $scope.authObj.$signInWithEmailAndPassword(login, pass)
    .then(function(firebaseUser) {
       console.log("Signed in as:", firebaseUser.uid);
    }).catch(function(error) {
       console.error("Authentication failed:", error);
    });
   }
 }
]);

您没有提供HTML代码，但我假设您有一个这种格式的表单

<form name="myForm">
<input type="login" ng-model="myForm.login">
<input type="password" ng-model="myForm.pass">
<input type="submit" value="Submit">
</form>

不要在

$scope.login

函数中使用

$scope

作为参数名：

app.controller("AuthCtrl", ["$scope", "$firebaseAuth", 
function($scope, $firebaseAuth) {
  //ERRONEOUS
  //$scope.login = function($scope) {
  //INSTEAD
  $scope.login = function() {
    var login = 'user@example.com';
    var pass = '12345';

    $scope.authObj = $firebaseAuth();
    $scope.authObj.$signInWithEmailAndPassword(login, pass)
    .then(function(firebaseUser) {
        console.log("Signed in as:", firebaseUser.uid);
    }).catch(function(error) {
        console.error("Authentication failed:", error);
   });
  }
 }
]);

通过使用

$scope

作为

$scope.login

的第一个参数，它隐藏了注入控制器构造函数中的

$scope

对象引用。

请参阅。通过将模型与视图以及视图与模型同步，提供双向数据绑定。Angular 1.6.3、Firebase 3.8.0、Angularefire 2.3.0我将遵循以下步骤：

app.controller("AuthCtrl", ["$scope", "$firebaseAuth", 
function($scope, $firebaseAuth) {
  //ERRONEOUS
  //$scope.login = function($scope) {
  //INSTEAD
  $scope.login = function() {
    var login = 'user@example.com';
    var pass = '12345';

    $scope.authObj = $firebaseAuth();
    $scope.authObj.$signInWithEmailAndPassword(login, pass)
    .then(function(firebaseUser) {
        console.log("Signed in as:", firebaseUser.uid);
    }).catch(function(error) {
        console.error("Authentication failed:", error);
   });
  }
 }
]);
