javascript - 如何从 Backbone.LocalStorage 获取 Backbone.Collection

Question

假设我可以从 javascript 控制台获得以下结果：

var ls = new Backbone.LocalStorage("items"); 
ls; // {"name":"items","records":["1244f588-be3d-c493-5c86-b2abb997af82"]}

我应该如何Backbone.Collection从Backbone.LocalStorage？

PS：
集合看起来像

[
{
"title":"test",
"completed":false,
"order":1,
"id":"1244f588-be3d-c493-5c86-b2abb997af82"
},
{
"title":"test2",
"completed":false,
"order":2,
"id":"8a8658b9-b636-eac3-4c54-03c279a73c2d"
}
]

创建一个空集合并collection.localStorage设置为您的Backbone.LocalStorage对象并获取它：

var c = new Backbone.Collection();
c.localStorage = new Backbone.LocalStorage("items");
c.fetch();
console.log(c.pluck('id'));

或findAll在您的Backbone.LocalStorage对象上使用以获取存储中的模型数组：

var ls = new Backbone.LocalStorage("items");
console.log(ls.findAll());
