Backbone.Collection.fetch() 在使用 jQuery.Mockjax 模拟生成的 JSON 时总是返回 404

Question

我有一个简单的设置，如下所示：

Main.js：

(function($) {
    "use strict";

    var Company = Backbone.Model.extend({
        defaults: {
                  title: "",
                  description: ""
        },

        initialize: function() {
            console.log ("New Company Created");
        }
    });

    var Search = Backbone.Collection.extend({
        url: '/api/companies',
        model: Company
    })

    var s = new Search();

    s.fetch();
})(jQuery);

Mockjax.js

$.mockjax({
    url: '\/api\/companies',
    contentType: 'text/json',
    responseTime: 150,
    type: 'GET',
    response: function (settings) {
        "use strict";
        this.responseText = [];

        for ( var i=0; i<=100; i++) {
            this.responseText.push({ title: "Title " + i, description: "Description"})
        }

    }
})

这就是我执行它时发生的情况：

GET http://localhost:63342/api/companies 404 (Not Found) jquery.js:8526
XHR finished loading: "http://localhost:63342/api/companies". 

但如果我在控制台中执行$.get('/api/companies');，我会正确理解：

$.get('/api/companies');
MOCK GET: /api/companies 
Object {url: "/api/companies", type: "get", isLocal: false, global: true, processData: true…}
 jquery.mockjax.js:546
Object {readyState: 1, getResponseHeader: function, getAllResponseHeaders: function, setRequestHeader: function, overrideMimeType: function…}

知道为什么会这样吗？

你可以试试这个方法：http://japhr.blogspot.in/2011/10/overriding-url-and-fetch-in-backbonejs.html

我想对你有帮助

 var Appointments = Backbone.Collection.extend({
          model: Models.Appointment,
          initialize: function(options) {
            options || (options = {});
            this.date = options.date;
          },
          url: function () {
            return '/appointments/' + this.date;
          },
          setDate: function(date) {
            this.date = date;
            this.fetch();
          },
          parse: function(response) {
            return _(response.rows).map(function(row) { return row.value ;});
          }
        });

这是一个 jQuery.mockjax 错误，而不是 Backbone。它被严重包含在 HTML 中的错误位置。
