我可以在Backbone中使用這個回調結果嗎？

我希望有人能夠幫助我，因爲我已經嘗試了一週以上，看看我是否可以使用此回調結果填充Backbone模型/集合。我可以在Backbone中使用這個回調結果嗎？

具體來說，我想列出的區域名稱和AreaGUID - 我也想從PriceMatrix總價。

PriceMatrix一邊 - 我甚至會滿足於區域名稱和AreaGUID，我會希望瞭解如何遍歷這個JSON，並從其嵌套值使集合。

JSON：

收藏：

Entities.AreaCollection = Backbone.Collection.extend({ 
    initialize: function() { 
     this.on('all', function(e) { console.log("Area event: " +e); }); 
    }, 
    url: "./murmurs.json", 

model: Entities.Area, 
    parse : function(response){ 
    return response.Result; 
    } 
});

，如果你能請幫助 - 謝謝！

你還可以分享你的模型和集合定義嗎？ – bvoleti

我在原來的文章中增加了一個thoise - 謝謝bvoleti –

你可以有一個簡單的分層設計這樣的...

var RootModel = Backbone.Model.extend({ 
default: 
    { 
     "CustomCallback": "", 
     "ErrorDescription": "", 
     "EvalMe": "", 
     "HasError": false, 
     "Result": null 
    } 
}); 

var ResultModel = Backbone.Model.extend({ 
default: 
    { 
     "__type": "", 
     "Areas": [] 
    } 
}); 

var AreaCollection = Backbone.Collection.extend({ 
    model: areaDetailsModel 
}); 

var AreaDetailsModel = Backbone.Model.extend({ 
default: 
    { 
     "Area": null, 
     "AreaMap": null, 
     "Connector": null 
    } 
}); 

var AreaModel = Backbone.Model.extend({ 
default: 
    { 
     "AreaGuid": "", 
     "AreaMapGuid": "", 
     "DefaultSeatingType": 0, 
     "GADefaultSettings": null, 
     "Name": "", 
     "NameForReports": "", 
     "Ordinal": 0, 
     "ParentHallGuid": "", 
     "StandId": null, 
     "StandName": null 
    } 
}); 

var AreaMapModel = Backbone.Model.extend({ 
default: 
    { 
     "AreaMapGuid": "", 
     "DescriptionLevel": "", 
     "GASettings": null, 
     "GateCombinations": null, 
     "IncludedInMultipleVersions": false, 
     "Name": "", 
     "NumberOfSeats": 0, 
     "ParentAreaGuid": "", 
     "SeatingType": 0, 
     "Sectors": null, 
     "Status": 0, 
     "TurnstileCombinations": null, 
     "PriceLevelIds": [] 
    } 
});

....

然後，您可以將您的回調結果向rootModel。

var rootModel= new RootModel("your callback to JSON"); 

var resultModel = new ResultModel(rootModel.get("Result")); 

var areas = new AreaCollection(resultModel.get("Areas")); 

var areaDetail = areas.at(0); 

var area = new AreaModel(areadetail.get("area");

...

不錯 - 感謝您花時間把它作爲我可能的答案。我現在去看看併發布。 –

所以最後一行有：** VAR面積=新AreaModel（areadetail.get（「區域」））; **犯規認識areadetail –

SOOO感覺接近 - 但改爲** ** areaDetail說**類型錯誤：areaDetail是未定義 \t VAR面積=新AreaModel（areaDetail.get（「區」））; ** –

我還沒有嘗試過，但是這可能會工作。

var area_detail_model = Backbone.Model.extend({ 
    defaults: { 
    AreaGuid: null, 
    AreaMapGuid: null 
    } 
}); 

var area_map_model = Backbone.Model.extend({ 
    defaults: { 
    AreaMapGuid: null, 
    DescriptionLevel: null 
    } 
}); 

var area_model = Backbone.Model.extend({ 
    defaults: { 
    Area: new area_detail_model(), 
    AreaMap: new area_map_model(), 
    Connector: [] // can declare a model for connector also 
    DependencyTags: [] // when using an array we can write bb_obj.get('Attr').ArrayItemName 
    }, 
    parse : function(response){ 
    // at this point only area models exist, i.e from area collection each area model 
    // is passed to this parse method 
    response.Area = new area_model(response.Area); 
    response.AreaModel = new area_map_model(response.AreaModel); 
    return response; 
    } 
}); 

var area_collection = Backbone.Collection.extend({ 
    model: area_model, 
    url: '/Areas', 
    parse : function(response){ 
    return response; // place a break point and check out the contents of response 
    } 
}); 

var result_model = Backbone.Model.extend({ 
    defaults: { 
    Areas: new area_collection(), 
    Id: null, 
    Pricing: null, 
    }, 
    url: '/GetResults', 
    parse : function(response){ 
    response.Result.Areas = new area_collection(response.Result.Areas); 
    return response.Result; // this will return only the Result section from your JSON 
    } 
}); 

var result_obj = new result_model(); 
result_obj.fetch();

因此，當反應是取那麼result_model解析功能將只挑選從JSON結果，然後我們創建了一個集合了區域，爲每個集合和方法對應的解析將按順序被調用。讓我知道它是否有效。

我可以在Backbone中使用這個回調結果嗎？
