從服務AngularJS

Question

比較JSON數據綁定值使用服務，我成功地檢索一個JSON數組，我則抽數據到我的控制器，並試圖用數據綁定值作爲用戶比較輸入了什麼，他們會就像他們的用戶名一樣，但是當值匹配時我沒有顯示日誌。以下是我有：

角服務：

loginApp.factory('userData', function($http, $log) { 
    return { 
     getUsers: function(scb) { 
      $http({method: 'GET', url: 'somelink/ajax/current_users.php'}). 
        success(function(data, status, headers, config) { 
       $log.info(data, status, headers(), config); 
       scb(data); 
      }). 
        error(function(data, status, headers, config) { 
       $log.warn(data, status, headers(), config); 
      }); 

     } 
    }; 
}); 

我的控制器：

loginApp.controller('loginController', 
     function loginController($scope, userData) { 

      // If I run a log on the `activeusers` 
      // I get the same console log as below  
      userData.getUsers(function(current_users) { 
       $scope.activeusers = current_users; 
      }); 

      $scope.createAccnt = { 
       fname: "", 
       lname: "", 
       username: function(inValue) { 
        for (var i = 0; i < $scope.activeusers.length; i++) { 
         if ($scope.activeusers[i].username == inValue) { 
          console.log("Username matches existing!!"); 
         } 
        } 
       }, 
       email: "" 
      }; 
} 

---

JSON數組返回：

[ 
    { 
     "user_id": "1", 
     "username": "userone", 
     "password": "", 
     "first_name": "", 
     "last_name": "", 
     "email": "", 
     "active": "", 
     "auth_token": "" 
    }, 
    { 
     "user_id": "2", 
     "username": "usertwo", 
     "password": "", 
     "first_name": "", 
     "last_name": "", 
     "email": "", 
     "active": "", 
     "auth_token": "" 
    } 
] 

控制檯顯示的狀態碼200並顯示所有的數據需求相關捐資，它與此類似：

[Object, Object] 
> 0 
    user_id: "1" 
    username: "userone" 
    password: "" 
    first_name: "" 
    last_name: "" 
    email: "" 
    active: "1" 
    auth_token: "" 
    __proto__: Object 
> 1 
    user_id: "2" 
    username: "usertwo" 
    password: "" 
    first_name: "" 
    last_name: "" 
    email: "" 
    active: "1" 
    auth_token: "" 
    __proto__: Object 

我所有的數據完全結合的作品，只是比較。我的for循環或我的if語句不正確？

很抱歉，如果我不是瞭解您的問題，而是應該

for (var i = 0; i < $scope.createAccount.length; i++) { 
    if ($scope.createAccount[i].username == inValue) { 
     console.log("Username matches existing!!"); 
    } 
} 

真的

for (var i = 0; i < $scope.activeusers .length; i++) { 
    if ($scope.activeusers [i].username == inValue) { 
     console.log("Username matches existing!!"); 
    } 
} 

與activeusers更換的createAccount
