困惑与Backbone.js分页

Question

我想介绍使用backbone.js paginator plugin的requestPager分页。

问题：建立延伸Backbone.Paginator.requestPager的collection后，我刷新网页和JavaScript控制台抛出错误：

Uncaught TypeError: Object function (a){return new m(a)} has no method 'result' backbone.paginator.js:678

我很新的骨干，是不知道该怎么去错误。是因为我使用了fetch()，它出现在下面错误的屏幕截图中？我还注意到没有GET请求被发送到后端。发生了什么，我该如何解决这个问题？谢谢！

JS代码

// Collection 

window.ListingCollection = Backbone.Paginator.requestPager.extend({ 
    model: Listing, 

    paginator_core: { 
     type: 'GET', 
     dataType: 'jsonp', 
     url: 'api/listings' 
    }, 

    paginator_ui: { 
     firstPage: 0, 
     currentPage: 0, 
     perPage: 10, 
     totalPages: 10 
    }, 

    server_api: { 
     '$filter': '', 
     '$per_page': function() { return this.perPage; }, 
     '$current_row': function() { return this.currentPage * this.perPage; }, 
     '$order_by': 'listing_id' 
    }, 

    parse: function(response){ 
     this.totalPages = Math.floor(response.total_rows/this.perPage); 
    } 

}); 

JS代码

// Router 
var AppRouter = Backbone.Router.extend({ 
    routes: { 
     '': 'listings', 
     'listings': 'listings' 
    }, 

    listings: function() { 
     var self = this; 

     // Load initial search results 
     this.listingList = new ListingCollection(); 
     this.listingList.fetch({ 
      success: function() { 
       self.listingListView = new ListingListView({ model: self.listingList }); 
       $('#listing_list table').append(self.listingListView.render().el); 
      } 
     }); 
     this.listingFilterView = new ListingFilterView(); 
    } 
}); 

在Javascript控制台截图误差

您可能正在使用下划线的旧版本包括。我使用1.3.1，它没有result()方法。下载他们的新产品version 1.3.3 - 它有result()。
