私は backbone.js を使用しており、コレクションのデータをサーバーから取得したいと考えています。

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());

サーバーの応答:

{"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() は空の配列 ([ ]) を返します。コードの何が問題なのか教えてください。

したがって、WiredPrairie が言ったように、これらの行を変更する必要があります。

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

に：

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.
