Javascript 作为阵列的主干文件列表

我是新手

我试图从RESTAPI加载文件夹的文件列表，并将其作为数组保存到localstorage，然后稍后使用localstorage数据呈现视图

我正在使用主干脱机适配器

我设法将数据从REST加载到localStorage，但未能将加载的数据保存为数组

它为localStorage中的每个文件创建多个记录

file-0001    [{"id":"1", "folderid":"0001","name":"file number one","size":"1000"}, {"id":"2", "folderid":"0001","name":"file number two","size":"1000"},{"id":"3", "folderid":"0001","name":"file number three","size":"1000"},{"id":"4", "folderid":"0001","name":"file number four","size":"1000"},{"id":"5", "folderid":"0001","name":"file number five","size":"1000"}]

这就是我得到的

file-1  {"id":"1", "folderid":"0001","name":"file number one","size":"1000"}
file-2  {"id":"2", "folderid":"0001","name":"file number two","size":"1000"}
file-3  {"id":"3", "folderid":"0001","name":"file number three","size":"1000"}
file-4  {"id":"4", "folderid":"0001","name":"file number four","size":"1000"}
file-5  {"id":"5", "folderid":"0001","name":"file number five","size":"1000"}

但这正是我需要的

在localStorage中，每个文件夹只需要一条记录

file-0001    [{"id":"1", "folderid":"0001","name":"file number one","size":"1000"}, {"id":"2", "folderid":"0001","name":"file number two","size":"1000"},{"id":"3", "folderid":"0001","name":"file number three","size":"1000"},{"id":"4", "folderid":"0001","name":"file number four","size":"1000"},{"id":"5", "folderid":"0001","name":"file number five","size":"1000"}]

更新：

directory.FILES = Backbone.Model.extend({});
directory.FOLDER = Backbone.Collection.extend({

    initialize: function() {
        return this.storage = new Offline.Storage("folder-files", this, {
            autoPush: !0
        })
    },
    url: "api/folder/files", //this will return json data [{"id":"1", "folderid":"0001"},{...},{...}]

    model: directory.FILES
});

    var FOLDER = new directory.FOLDER();
    FOLDER.fetch();

您是否可以更新您的答案，以包括您的模型和用于将数据持久化到

本地存储中的调用？

？刚刚在主干线脱机Github页面上检查，发现作者建议当前不要使用它：也许您最好使用它，它正在积极开发中它与文件夹列表配合良好，我唯一搞不懂的是将json数据作为数组保存到一个LOCALSTORAGE密钥中。其中有一些奇怪的约定。。。您正在对模型和集合使用

CONSTANT\u CASE

；对于这两种情况，使用

CamelCase

都有一个很强的惯例。还有什么是

！0

在那里做什么？我想这是为了

真的

，我不确定，github page是这么说的。自动推送支持同步。
