如何使用backbone.js填充服務器數據的模型

Question

我是backbone.js的初學者。我有一個模型的屬性和引用該模型的集合。我需要從後端獲取數據並使用這些數據填充模型。但我無法做到。

數據從服務器來是：

[{"aaData": 
    [ 
    {"customer_id":2,"bom_id":19, 
     "bom_name":"Anonymous123", 
     "bom_description":"Anonymous123", 
     "last_modified":"2014-02-13 12:15:54.0", 
     "bom_status":"d", 
     "version":1, 
     "pu_id":1}, 

    {"customer_id":3,"bom_id":20, 
     "bom_name":"bom_idea_AU", 
     "bom_description":"mfsBomIdea", 
     "last_modified":"2014-02-13 12:16:46.0", 
     "bom_status":"d", 
     "version":1, 
     "pu_id":2} 
    ], 
    "customerId":"", 
"bomId":"", 
"bomName":"", 
"bomDescription":"", 
"lastModified":"", 
"version":"", 
"bomStatus":""} 
] 

到目前爲止的代碼：

var bomRecordModel = Backbone.Model.extend({ 
    defaults : { 
        customerId: "", 
        bomId: "", 
        bomName : "", 
        bomDescription: "", 
        lastModified: "", 
        version: "", 
        bomStatus: "" 

       }, 

}); 
var bomRecordObj = new bomRecordModel(); 


var bomRecordCollection = Backbone.Collection.extend({ 
      model : bomRecordModel, 
      url: "/easybom/easybom?opcode=6&pu_id=0" 
}); 
var brcObject = new bomRecordCollection(); 
brcObject.fetch(); 

理想情況下，應該獲取數據後返回兩款車型

MODEL1：

{"customer_id":2, 
"bom_id":19, 
"bom_name":"Anonymous123", 
"bom_description":"Anonymous123", 
"last_modified":"2014-02-13 12:15:54.0", 
"bom_status":"d", 
"version":1, 
"pu_id":1} 

MODEL2 ：

{"customer_id":3, 
"bom_id":20, 
"bom_name":"bom_idea_AU", 
"bom_description":"mfsBomIdea", 
"last_modified":"2014-02-13 12:16:46.0","bom_status":"d", 
"version":1,"pu_id":2} 

請幫我一把。

您需要aprse從你的服務器的響應：

var bomRecordCollection = Backbone.Collection.extend({ 
      model : bomRecordModel, 
      url: "/easybom/easybom?opcode=6&pu_id=0", 
      parse: function(response){ 
       return response.aaData; 
      } 
});
