骨干无法解析json

Question

I am using backbone.js, and trying to fetch some json from twitter, but it doesn't work, the collection's length is 0. Here's the code.

var Tweet = Backbone.Model.extend();

var Tweets = Backbone.Collection.extend({
    model: Tweet,
    url: 'http://api.twitter.com/1/favorites.json?screen_name=dhh',
    parse: function(response) {
        return response.results;
    }
});

var tweets = new Tweets();
tweets.bind('reset', function(tweets) {
   alert(tweets.length);
});
tweets.fetch();

Answer 1

try

parse: function(response) {
  return response;
}

pointing my browser to api.twitter.com/1/favorites.json?screen_name=dhh i don't see a .results property, just an array with objects

Answer 2

解决方案是摆脱parse函数，该函数具有与其他答案相同的效果，并添加＆callback =？
