Question

该功能可以工作并将用户输入提交给我的firebase＆＃34;后端＆＃34;但是在使用ng-submit之后我无法弄清楚清空输入字段的明确功能。输入与var＆＃34; emailInput＆＃34;相关联。与ng模型。谢谢你的任何建议！

var newEmailref = new Firebase("https://nevermind.com");
$scope.email = $firebaseArray(newEmailref);
$scope.addEmail = function(email) {
    $scope.email.$add(email);
    $scope.emailInput = '';
};

Answer 1

我需要为电子邮件输入分配一个键，也需要一个空对象。

$scope.emailInput = {};
var newEmailref = new Firebase("https://archerthedog.firebaseio.com/email");
    $scope.email = $firebaseArray(newEmailref);
    $scope.addEmail = function(email) {
        $scope.email.$add(email);
        $scope.emailInput = {};
    };

Answer 2

您的代码只需稍加修改即可使用$scope.email = "";代替$scope.emailInput = '';：

var newEmailref = new Firebase("https://nevermind.com");
$scope.email = $firebaseArray(newEmailref);
$scope.addEmail = function(email) {
  $scope.email.$add(email);
  $scope.email = '';
};

Answer 3

我没有得到你....如果在firebase数据库中添加一个项目，数据库将创建键值，如果你这样做

@Override
protected void onPostExecute() {
    Intent intent = new Intent(login.this, MainActivity.class);
    intent.putExtra("driver_obj" , driver); // driver should be declared as global in `UserLoginTask` class.
    activity.startActivity(intent);

    overridePendingTransition(R.anim.right_in, R.anim.left_out);
    finish();
}

对于takeData.key，console.log的回答是一些id值（-Ko7cGuymlshrS2JQEEC）然后，takenData.val（）。email）是一个电子邮件地址......

       See the Full code of mine it's working for me

    var ref = firebase.database().ref();
    var firebasedata = $firebaseObject(ref);



  var messagesRef = ref.child("storeUserData");
  var data = $firebaseArray(messagesRef)

  $scope.createItem= function(user) {
        data.$add(user).then(function(data) {
           $scope.user = "";
              var myPopup = $ionicPopup.show({
           title: 'Dear User, Your Account has created Successfully',
         });
      $timeout(function() {
          myPopup.close(); //close the popup after 6 seconds for some reason
       }, 6000);
         });
      }
      ref.orderByValue().on("value", function(data) {
        data.forEach(function(takenData) {
         console.log("The " + takenData.key + " rating is " + 
       takenData.val().email);
        });
        });

角度提交后清除firebase功能的输入字段
