将JSON载入骨干模型

Question

I am trying to load a json file into a backbone model like so :

var Feed = Backbone.Model.extend();

var FeedCollection = Backbone.Collection.extend({
    model: Feed,
    url:'feed.json'


var feeds = new FeedCollection();

feeds.fetch({success : function() {
       console.log(feeds);
}})

The first log returns the JSON obect within the file, just returns an object without the json data.

You should try and mention a few more properties for your fetch call. Try passing in the method argument and the dataType argument. If you are getting JSONP, try passing in callback too. Here is a code snippet I use that should help you out -

feeds.fetch({
    method:"GET",
    dataType: 'jsonp',
    jsonp: 'callback'
}).complete(function(resp) {
    // Do stuff here
});
