Backbone Collection jsonp ajax 结果未正确生成模型 [英] Backbone Collection jsonp ajax results not generating model correctly

问题描述

http://jsfiddle.net/nf8NM/3/

这是我第一次涉足 Backbone，我只是想从 Dribbble 获取 Api 调用.

This is my first foray into Backbone and I am simply trying to fetch an Api call from Dribbble.

我正在尝试以最 Backbone-native 的方式做到这一点.然而，它似乎在做一些有趣的事情，因为它制作了这个系列.

I'm trying to do it the most Backbone-native kind of way. However it seems to be doing something funny at the point it makes the collection.

此时我并不担心实际渲染，我只是希望集合能够为来自 Api 的每个响应正确设置一个模型.

I am not so bothered about actually rendering at this point, I just want the collection to setup properly with a model for each of the responses from the Api.

任何提示和方向都会很棒.我完全做错了吗?

Any hints and direction would be great. Am I completely doing this all wrong?

推荐答案

不确定您的问题是什么.重写一下你的集合类来分离关注点，我得到了完全有效的模型.

Not sure what your problem is. Rewriting a bit your collection class to separate the concerns, I get perfectly valid models.

Shot = Backbone.Model.extend({
    initialize:function(opts) {
        console.log("init shot : "+opts.id);
    }
});
ShotsList = Backbone.Collection.extend({
    model: Shot,
    sync: function(method, model, options) {
        var params = _.extend({
            type: 'GET',
            dataType: 'jsonp',
            url: model.url(),
            processData: false
        }, options);

        return $.ajax(params);
    },
    parse: function(response) {
        return response.shots;
    },

    url: function() {
        return "http://api.dribbble.com/players/" + encodeURIComponent(this.player) + "/shots?per_page=18";
    }
});

s=new ShotsList();
s.bind("reset",function(collection) {
    console.log(collection.models);
    console.log(collection.pluck("image_teaser_url"));
});
s.player="jordan";
s.fetch();
