javascript - Backbone JS : self populate Collection

Question

我有一个像这样的 Backbone 集合

var ContactsCollection = Backbone.Collection.extend({
    model: Contact,

    initialize: function () {
            //retrieves contacts from web service
            //contactsLoaded: is the callback that gets called after 
            //the contacts get received
            loadContacts(this.contactsLoaded);
    },

    contactsLoaded: function (contacts) {
            for (var i = 0; i < contacts.length; i++) {
              //TODO populate the collection [models][1]
            }
    }
});

换句话说，我想自行填充集合的 models , 我该怎么做？

考虑使用 REST API 作为 Collection#fetch应该完全按照您的意愿行事。

var ContactsCollection = Backbone.Collection.extend({
model: Contact,
url: '', // set the URL
initialize: function () {
  this.fetch();
}});
