覆盖 Backbone 的 Collection-fetch [英] override Backbone's Collection-fetch

问题描述

我想以非 RESTful 方式获取我的集合，所以我决定用

I want to get my collection in a NON-RESTful way, so I decide to override the Collection.fetch with

App.carClc = Backbone.Collection.extend({
    model : App.cardModel,
    url : 'http://localhost/bbtest/data.php',
    fetch : function() {
        $.ajax({
            type : 'GET',
            url : this.url,
            success : function(data) {
                console.log(data);
            }
        });
    }
});

我不知道如何将我的收藏设置为响应.我是 BackboneJS 的新手，谢谢大家！

I don't know how to set my collection to the response. I'm new to BackboneJS, thanks all of you!

推荐答案

如果你想给 fetch 添加一个自定义的装饰器"，但又不想完全覆盖它，试试:

If you want to add a custom "decorator" to fetch, but not override it completely, try:

    var MyCollection = Backbone.Collection.extend({

        //custom methods

        fetch: function(options) {

            //do specific pre-processing 

            //Call Backbone's fetch
            return Backbone.Collection.prototype.fetch.call(this, options);
        }

  });    

在这里，您不必推出自己的 $.ajax

Here, you don't have to roll out your own $.ajax

此外，如果您想使用由 Backbone 的 fetch 方法返回的 jQuery 承诺，请不要忘记最后一行中的 return.

Also, don't forget the return in the last line if you want to use the jQuery promise returned by Backbone's fetch method.
