javascript - 如何从 fetch :success event? 中获取这个集合

Question

有没有办法从成功事件中引用所有者集合。 例如，我正在使用 this 来引用集合:

var col = Backbone.Collection.extend({
model: MobileService,
url: 'file.json',

initialize: function(){
    this.fetch({
        success: function(){
            this.trigger('fetched'); 
        },
...

Answer 1

来自fine manual :

fetch collection.fetch([options])

[...] The options hash takes success and error callbacks which will both be passed (collection, response, options) as arguments.

所以你可以使用:

this.fetch({
    success: function(collection) {
        collection.trigger('fetched');
    }
});
