javascript - "Object doesn' t 支持属性或方法 'push' "

Question

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

"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 的样子:

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

我想将状态附加/添加到上面的 json 中，添加 status 属性后看起来像这样:

{"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数组的一个方法。

但是应用程序只是一个对象(不是数组)。这里我们可以直接使用:

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