JSON格式分層數據

-1

我有這樣的JSON數據data:[ {'country':'uk','district':'whitefield','ward':'eastward','county':'eastcounty1','company':'privatecompany'}, {'country':'uk','district':'whitefield','ward':'eastward','county':'eastcounty1','company':'privatecompany2'}, {'country':'uk','district':'whitefield','ward':'eastward','county':'eastcounty2','company':'privatecompany3'}, {'country':'uk','district':'whitefield','ward':'westward','county':'westcounty1','company':'privatecompany'}, {'country':'uk','district':'blackfield','ward':'westward','county':'eastcounty1','company':'privatecompany'}, {'country':'india','district':'andhra','ward':'ramnagar','county':'','company':'privatecompany'} ]JSON格式分層數據

我不得不將其轉換爲階層結構如..

data:{'uk':{ 
     "whitefield":{ 
      "eastward":{ 
      "eastcounty1":["privateCompany","privateCompany2"], 
      "eastcounty2":["privatecompany3"] 
      }, 
      "westward":{ 
      "westcounty1":["privatecompany"], 
      "eastcounty1":["privatecompany"] 
      } 
      }, 
     "blackfield":{ 
      "westward":{"eastcounty1":["privatecompany"]}     
     } 
    }, 
"india":{ 
    "andhra":{ 
     "ramnagar":["privatecompany"] 
     } 
    }}

在上述情況下

我有縣=」「或在一個場景中，縣= null，因此它被替換爲如上所示在ramnagar病房。

你嘗試過什麼到目前爲止？我們願意幫助您，但我並沒有在這裏看到與* code *有關的問題。 – Jordy 2015-04-01 11:53:01

是的，我已經嘗試了很多方式使用for循環和所有，但我正在尋找一個適度和最好的方法來解決這個問題，希望你能理解 – 2015-04-02 17:19:51

你只需要遍歷每個項目，建立自己的JSON對象Fiddle here

function mergeData(data) { 
 
    var outp = {}; 
 

 
    // loop through each object and add 
 
    for (var i = 0; i < data.length; i++) { 
 
     var obj = data[i]; 
 
     if (outp.hasOwnProperty(obj.country)) { 
 
      if (outp[obj.country].hasOwnProperty(obj.district)) { 
 
       if (outp[obj.country][obj.district].hasOwnProperty(obj.ward)) { 
 
        if (outp[obj.country][obj.district][obj.ward].hasOwnProperty(obj.county)) { 
 
         outp[obj.country][obj.district][obj.ward][obj.county].push(obj.company); 
 
        } 
 
        else { 
 
         if (obj.county == "" || obj.county == null) { 
 
          if (Array.isArray(outp[obj.country][obj.district][obj.ward])) { 
 
           outp[obj.country][obj.district][obj.ward].push(obj.company); 
 
          } 
 
          else { 
 
           outp[obj.country][obj.district][obj.ward] = [obj.company]; 
 
          } 
 
         } 
 
         else { 
 
          outp[obj.country][obj.district][obj.ward][obj.county] = [obj.company]; 
 
         } 
 
        } 
 
       } 
 
       else { 
 
        outp[obj.country][obj.district][obj.ward] = {}; 
 
        outp[obj.country][obj.district][obj.ward][obj.county] = [obj.company];      
 
       } 
 
      } else { 
 
       outp[obj.country][obj.district] = {}; 
 
       outp[obj.country][obj.district][obj.ward] = {}; 
 
       outp[obj.country][obj.district][obj.ward][obj.county] = [obj.company]; 
 
      } 
 
     } else { 
 
      outp[obj.country] = {}; 
 
      outp[obj.country][obj.district] = {}; 
 
      
 
      if (obj.county == "") { 
 
       outp[obj.country][obj.district][obj.ward] = [obj.company]; 
 
      } 
 
      else { 
 
       outp[obj.country][obj.district][obj.ward] = {}; 
 
       outp[obj.country][obj.district][obj.ward][obj.county] = [obj.company]; 
 
      } 
 

 
     } 
 
    } 
 

 
    console.log(JSON.stringify(outp)); 
 
    return outp; 
 
}
