骨干网 - 从API获取JSON数据 [英] Backbone - Get JSON Data from API

问题描述

我在玩弄骨干这最后的日子..

I'm playing around with Backbone these last days..

我想从Twitter搜索API接收的一些数据。但我真的不明白它是如何工作的。这是我的code：

I want to receive some data from the twitter search API. But I don't really understand how it works. This is my code:

(function($){

Tweet = Backbone.Model.extend();

Tweets = Backbone.Collection.extend(
    {
        model: Tweet,

        url: 'http://search.twitter.com/search.json?q=Hamburg&rpp=5&lang=all&callback=?',
        parse: function(response)
        {
            return response.results;
        }
    });

DefaultTweetView = Backbone.View.extend(
    {
        initialize: function(){
          _.bindAll(this, 'render');
     }

        template: _.template('<p>@<%= from_user %> <em></em></p><p><%= text %></p><p><%= location %></p>'),
        render: function()
        {

            $(this.el).html(this.template(this.model.toJSON()));
            return this;
        }
    });
app = new Tweet();
})(jQuery);

我不认为这可能是正确的。但我不知道如何处理它:(有人能帮助我，或张贴一个链接，我可以按照有关JSON数据和骨干好吗？

I don't think this could be right. But I don't know how to handle it :( Could someone help me or post a link where I could follow some instructions about json data and backbone please?

推荐答案

您的实际code不起作用，因为你有一个语法错误，而你只是初始化模式。

Expications

Your actual code doesn't work because you have a syntax error, and you just initialized the model.

您不能访问Twitter的API不覆盖Backbone.sync法（同源策略的问题：<一href=\"http://en.wikipedia.org/wiki/Same_origin_policy\">http://en.wikipedia.org/wiki/Same_origin_policy,该解决方案已经张贴在这里：<一href=\"http://stackoverflow.com/questions/8430113/backbone-collection-jsonp-ajax-results-not-generating-model-correctly\">Backbone收藏JSONP AJAX结果无法正确生成模型的）

You can't access to Twitter API without overwrite the Backbone.sync method (problem of the same origin policy : http://en.wikipedia.org/wiki/Same_origin_policy, the solution has already posted here : Backbone Collection jsonp ajax results not generating model correctly)

在我看来，学习骨干的最好的事情JS是了解如何code ++工程，并帮助你，骨干JS文件是在这里：的http://documentcloud.github.com/backbone/

In my view, the best thing to learn Backbone JS is to understand how code works, and to help you, the Backbone JS documentation is here : http://documentcloud.github.com/backbone/

我创建了一个工作的jsfiddle与code在这里： http://jsfiddle.net/Atinux/v4K6A/

I created a working jsFiddle with your code here : http://jsfiddle.net/Atinux/v4K6A/

所以，有了它，你就可以开始更好地理解骨干JS。

So with it you can begin to better understand Backbone JS.
