我有一个RESTful json API,我需要在我的前端Backbone站点中访问它。
所以,我这样做了:
/* Goal collection */
var GoalCollection = Backbone.Collection.extend({
model: GoalModel,
url: "http://staging.api.hiwarren.com:8080/api/v1/goals/?callback=?",
sync: function(method, collection, options) {
options.dataType = "jsonp";
// options.timeout = 10000;
return Backbone.sync(method, collection, options);
},
parse: function(response) {
return response.results;
}
});
/* View for the goal collection */
var GoalCollectionView = Backbone.View.extend({
tagName: 'ul',
initialize: function(callback){
var that = this;
_.bindAll(this, 'render');
that.collection = new GoalCollection();
that.collection.bind('reset', this.render)
that.collection.fetch({
dataType: 'jsonp',
success: function(collection, response){
that.render();
if(callback) callback(that);
},
error: function(collection, response){
throw new Error("Goal fetch error - " + response.statusText);
}
});
},
render: function(){
this.collection.each(function(goal){
var goalView = new GoalView({ model: goal });
this.$el.append(goalView.render().el);
}, this);
return this;
}
});
我正在尝试使用JSONP,因为它是一个不同的域。我已经按照类似的问题回答了问题,正如你在我的代码中看到的那样,但它不起作用。
相反,我收到此错误消息:
Uncaught Error: Goal fetch error - load
Backbone.View.extend.initialize.that.collection.fetch.error
options.errorjquery.js:3094 jQuery.Callbacks.fire
jQuery.Callbacks.self.fireWithjquery.js:8261 done
jQuery.ajaxTransport.send.jQuery.prop.on.callback
jQuery.event.dispatchjquery.js:4116 jQuery.event.add.elemData.handle
我做错了什么?我怎样才能做到这一点?
答案 0 :(得分:1)
您确定要尝试访问的域是否支持jsonp
?某些网站仅启用json
格式。
