每个在主干视图中都不起作用渲染

我刚刚开始使用Backbone，并且在从某些JSON数据生成简单的html列表时遇到问题。每个在主干视图中都不起作用渲染

，我发现了错误

Uncaught TypeError: Object function(){return c.apply(this,arguments)} has no method 'each'

这里是我的代码

var Show = Backbone.Model.extend(); 

var ShowCollection = Backbone.Collection.extend({ 

    model: Show, 
    url: 'http://192.168.0.7:8081/api/0b08ecef4eda8c6a28b6be3164a96ac8/?cmd=history&type=downloaded&limit=50', 

    parse: function(response){ 
     return response.data; 
    } 

}); 

var ItemView = Backbone.View.extend({ 

    tagName: "li", 
    template: $("#item").html(), 

    render: function() { 
    var templ = _.template(this.template); 
    this.$el.html(templ(this.model.toJSON())); 
    return this; 
    } 

}); 

var ShowView = Backbone.View.extend({ 

    el: $("#history"), 
    initialize: function() { 
    this.collection = ShowCollection; 
    this.render(); 
    }, 
    render: function() { 
    this.collection.each(function(item) { 
     this.renderItem(item); 
    }, this); 
    }, 
    renderItem: function(item) { 
    var itemView = new ItemView({ model: item }); 
    this.$el.append(itemView.render().el); 
    } 

}); 

var history = new ShowView();

这里是我的数据

{ 
data: [
