無法讀取未定義的數據？這裏JSON

是我的代碼使用JS來保存值無法讀取未定義的數據？這裏JSON

self.Save = function (e) { 

    if (vm_Currencies.selectedRow.CurrencyName == null) { 
      alert("Fill Some Thing"); 
    } 
    if (vm_Currencies.selectedRow.CurrencyCode != null) { 
     debugger; 

     var text1 = { "CurrencyCode": vm_Currencies.selectedRow.CurrencyCode, "CurrencyName": vm_Currencies.selectedRow.CurrencyName, "CurrencySign": vm_Currencies.selectedRow.CurrencySign, "DecimalPlaces": vm_Currencies.selectedRow.DecimalPlaces, "PositiveFormat": vm_Currencies.selectedRow.PositiveFormat, "NegativeFormat": vm_Currencies.selectedRow.NegativeFormat, "CurrencyStatus": vm_Currencies.selectedRow.CurrencyStatus }; 
     self.dsProduct.add(text1); 
     ///////////error comes here while i call sync() 
     self.dsProduct.sync(); 
    ////cannot read data of undefined 
    } 
    if (e.data.CurrencyName != null) { 
     debugger; 
     var text2 = { "CurrencyName": e.data.CurrencyName, "CurrencySign": e.data.CurrencySign, "DecimalPlaces": e.data.DecimalPlaces, "PositiveFormat": e.data.PositiveFormat, "NegativeFormat": e.data.NegativeFormat, "CurrencyStatus": e.data.CurrencyStatus }; 
     self.dsProduct.add(text2); 
     /////////sucess 
     self.dsProduct.sync(); 
     /////sucess 
    } 

}

text2的工作，但文本1不工作時，我發送的值頂部控制器以節約durring debuuging我檢查格式boths格式是相同的我應該怎麼做同步的值，使服務器端接收他們更新用

這裏是兩個文本1和文本

CurrencyCode: 20 
    CurrencyName: "dollar" 
    CurrencySign: "$" 
    CurrencyStatus: "23" 
    DecimalPlaces: 1 
    NegativeFormat: "12" 
    PositiveFormat: "12" 
__proto__: Object

在控制檯調試格式通過查找到你的代碼唯一想到的是，在vm_Currencies.sele ctedRow.CurrencyCode是「未定義」。

您可以通過用戶瀏覽器調試器來檢查運行時的值。也試試這個

if(vm_Currencies.selectedRow.CurrencyCode != "undefined") 
{ 
//Code Here 
}

另一種選擇

if(vm_Currencies != "undefined") 
{ 
//Code here 
}

的代碼是完美的，我得到即使我已經編輯現在確認問題的意見 –

這是爲什麼不aceepting貨幣代碼它們是貨幣代碼值這只是一個問題 –

 self.Save = function (e) { 
        debugger; 
        if (vm_Currencies.selectedRow.CurrencyCode == null) 
        { 
         var GetValuesForSaving = { "CurrencyName": e.data.CurrencyName, "CurrencySign": e.data.CurrencySign, "DecimalPlaces": e.data.DecimalPlaces, "PositiveFormat": e.data.PositiveFormat, "NegativeFormat": e.data.NegativeFormat, "CurrencyStatus": e.data.CurrencyStatus }; 
        self.dsProduct.add(GetValuesForSaving); 
        self.dsProduct.sync(); 
        } 

        else 
        { 
         debugger; 
         var GetValuesForSaving = { "CurrencyC": vm_Currencies.selectedRow.CurrencyCode, "CurrencyName": vm_Currencies.selectedRow.CurrencyName, "CurrencySign": vm_Currencies.selectedRow.CurrencySign, "DecimalPlaces": vm_Currencies.selectedRow.DecimalPlaces, "PositiveFormat": vm_Currencies.selectedRow.PositiveFormat, "NegativeFormat": vm_Currencies.selectedRow.NegativeFormat, "CurrencyStatus": vm_Currencies.selectedRow.CurrencyStatus }; 
         self.dsProduct.add(GetValuesForSaving); 
        self.dsProduct.sync(); 
       } 

      }
