使用 angular 数据绑定从 Parse 检索和显示信息

Question

我正在使用 angular 数据绑定从 Parse 检索和显示信息。特别是，我想要的是用户在文本字段中输入的 ObjectID 在 query.get 中用于检索该特定用户的各种信息。这似乎不起作用，我想知道代码中是否有错字。

下面是Javascript代码：

Parse.initialize("ID", "ID");


angular.module('AuthApp', [])
.run(['$rootScope', function($scope) {
  $scope.scenario = 'Sign up';
  $scope.currentUser = Parse.User.current();


  $scope.signUp = function(form) {
    var user = new Parse.User();
    user.set("password", form.password);
        user.set("username", form.username);

    user.signUp(null, {
      success: function(user) {
window.location = 'myprofile.php'
      },
      error: function(user, error) {
        alert("Unable to sign up:  " + error.code + " " + error.message);
      }
    });    
  };

  $scope.userIdChanged = function () {
    var query = new Parse.Query(Parse.User);

    query.get($scope.userId, {
      success: function(userInfo) {
        // The object was retrieved successfully.
        var address = userInfo.get("Address");
        $scope.address = 'Address: ' + address;
      },
      error: function(object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and message.
      }
    });
  };

特别是受影响的部分：

$scope.userIdChanged = function () {
    var query = new Parse.Query(Parse.User);

    query.get($scope.userId, {
      success: function(userInfo) {
        // The object was retrieved successfully.
        var address = userInfo.get("Address");
        $scope.address = 'Address: ' + address;
      },
      error: function(object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and message.
      }
    });
}

下面是html部分：

});
</script>
</head>
<body ng-app="AuthApp">


  <div ng-show="currentUser">


  userId: <input type="text" ng-model="userId" ng-blur="userIdChanged()"/>
    <div>{{addresss}}</div>





  </div>
</body>
</html>

更新： 下面是显示的结果：

下面是html代码：

<!DOCTYPE html>
<html>
<head>
<script src="http://www.parsecdn.com/js/parse-1.2.12.min.js"></script>

    <script src="js/functions.js"></script>

  <script src="angular.js"></script>



</head>
<body ng-app="AuthApp">
    <div ng-controller="MyCntrl">
         userId: <input type="text" ng-model="userId" ng-blur="userIdChanged()"/>
            <div>{{addresss}}</div>
        ...
    </div>
    </body>
</html>

下面是javascript:

Parse.initialize("id", "id");


var module = angular.module("AuthApp", []);

module.controller("MyCntrl", function($scope){

$scope.userIdChanged = function () {
    // now access $scope.userId here
    var query = new Parse.Query(Parse.User);

    query.get($scope.userId, {
      success: function(userInfo) {
        // The object was retrieved successfully.
        var address = userInfo.get("Address");
        $scope.address = 'addresss: ' + address;
      },
      error: function(object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and message.
      }
    }
  };

});

将控制器与模块相关联，以在 scope 方法中访问 $scope 值。示例代码如下：

Html

<html>
    <head>
        ...
    </head>
    <body ng-app="AuthApp">
    <div ng-controller="MyCntrl">
         userId: <input type="text" ng-model="userId" ng-blur="userIdChanged()"/>
            <div>{{addresss}}</div>
        ...
    </div>
    </body>
</html>

Js

var module = angular.module("AuthApp", []);

module.controller("MyCntrl", function($scope){

$scope.userIdChanged = function () {
    // now access $scope.userId here
  };

});

试试这个，对你有帮助。
