Question

我正在尝试将新值添加到AngularJS中的现有JSON对象中，但我收到此错误消息：

"Object doesn't support property or method 'push'"

这是我的代码：

$scope.addStatus = function (text) {          
          $scope.application.push({ 'status': text }); //I have tried 'put' but getting the error
      };

 $scope.create = function( application ){
        $scope.addStatus('Under review');
 }

这是我的应用程序json看起来像：

{"type":"Not completed","source":"mail","number":"123-23-4231","amount":"234.44","name":"John ","id":"123","by_phone":true}

我想在上面的json中添加/添加状态，并在添加状态属性后显示：

{"type":"Not completed","source":"mail","number":"123-23-4231","amount":"234.44","name":"John ","id":"123","by_phone":true, "status": "under review"}

Answer 1

.push()是JS Array的一种方法。

但是应用程序只是一个对象（不是数组）。在这里我们可以使用：

// instead of this
// $scope.application.push({ 'status': text });
// use this
$scope.application.status = text;

Answer 2

Array.prototype.push仅适用于数组。以下列方式之一添加属性：

$scope.application['status'] = text;

或者：

$scope.application.status = text;

＆＃34;对象不支持属性或方法＆＃39; push＆＃39;＆＃34;
