骨干collection.fetch（），解析不起作用

Question

我正在使用ebrian.js，我想從服務器獲取我的收藏集的數據：

var Account = Backbone.Model.extend();
var AccountList = Backbone.Collection.extend({
        model: Account,

        url: '/pfp/accounts/service',

        parse: function(response){
            return response.Data;
        }

    });
var accountList = new AccountList;
accountList.fetch();
console.log(accountList.toJSON()); 

服務器響應：

{"Data":
[{"accountid":"101752","account_name":"hijklmnopq","userid":"1","comment":"mnopqrstu","creation_date":"6 Jan 2008","account_type":"2","acc_type_name":"Дебетовая карта","currency":"144","letter_code":"","start_balance":"90.000.000","start_balance_raw":90000000.000,"to_total":true},
{"accountid":"144924","account_name":"emabcefghijklmnopqr","userid":"1","comment":"lmno","creation_date":"19 Jan 2008","account_type":"4","acc_type_name":"Банковский счёт","currency":"113","letter_code":"Le","start_balance":"360.000.000,00","start_balance_raw":360000000.000,"to_total":true},
...

accountList.toJSON（）返回空數組（[]）。 請幫助我代碼有什么問題。

因此，正如WiredPrairie所說，您需要更改這些行：

accountList.fetch();
console.log(accountList.toJSON()); 

至：

accountList.fetch({
  success: function(collection){
    // This code block will be triggered only after receiving the data.
    console.log(collection.toJSON()); 
  }
});
// JS will likely reach this line before receiving the data.
