以下是我的文件：
var bb = {
models: {},
collections: {},
views: {},
router: null
};
bb.models.Route = Backbone.Model.extend({
code: null,
terminals: [],
stops_forwards: [],
stops_backwards: [],
departure_times_forwards: [],
departure_times_backwards: [],
initialize: function (pk) {
var obj = this.request(pk);
this.code = obj.code;
this.terminals = obj.terminals;
this.stops_forwards = obj.stops_forwards;
this.stops_backwards = obj.stops_backwards;
this.departure_times_forwards = obj.departure_times_forwards;
this.departure_times_backwards = obj.departure_times_backwards;
},
request: function (pk) {
var res = $.ajax({
url: "http://1.2.3.4:1900/api/v1/route/"+pk,
method: "GET"
});
// <1>
if (res.status === 200) {
return res.responseJSON;
}
}
});
我想在Route.request方法中调用Method.initialize方法，以便获取数据。我想通过以下方式在Mozilla控制台中进行测试：
var myR = new bb.models.Route("285");
但是，这会引发错误：
TypeError ：obj未定义。
我得到的数据类似于：
{
"code":285,
"terminals":[
"EVKA 1",
"KONAK"
],
