如何将一些数据从Json推送到AngularJS的新数组中?

问题描述：

假设我有这个Json ..

Let's say I have this Json ..

{
    "name": "Mark",
    "gender": "male",
    "account1": {
        "accountNo": 1201,
        "balance": 300
    },
    "account2": {
        "accountNo": 1354,
        "balance": 5000
    }
}

我期望的是..

$scope.myArray = [
    {
        "accountNo": 1201,
        "balance": 300
    },
    {
        "accountNo": 1354,
        "balance": 5000
    }
];

在AngularJS中，如何选择Json数据的一部分并将其迭代地推送到数组中(我的意思是，当我拥有account1，account2 account3或更多时，它仍然可以将它们添加到数组中).

In AngularJS, how can I pick some part of Json data and push it into an array iteratively( I mean, when I have account1, account2 account3 or more, it can still add them into the array).

答

您通常可以将数组分配过来，但是在这种情况下，由于您的数组是psuedo，这是不可行的.

You could normally just assign the array over, but in this scenario that is not an option because your array is psuedo.

理想情况下，您希望能够执行以下操作(相关问题):

Ideally you would like to be able to do what this answer (related question) does: How to return and array inside a JSON object in Angular.js which is simply

$scope.myArray = json.accounts;

但是，如上所述，您没有帐户数组，因此需要创建一个.

However, as noted, you do not have an accounts array so you need to make one.

var accounts = [];
for(var key in json){
 if( !json.hasOwnProperty(key) // skip prototype extensions
  || !json[key].hasOwnProperty("accountNo") //skip non account objects
 ) continue; 
 accounts.push(json[key]);
}

现在您可以使用此数组

$scope.myArray = accounts;
