如何僅添加2個JSON數組的整數對象？

Question

我有以下值的兩個JSON數組，

var data1 = [{ 
     "keyword": "Jan","PotentialAmmount": 450000,"EarnedAmmount": 250000}, { 
     "keyword": "Feb","PotentialAmmount": 650000,"EarnedAmmount": 400000}, { 
     "keyword": "Mar","PotentialAmmount": 350000,"EarnedAmmount": 200000}]; 

var data2 = [{ 
     "keyword": "Jan","PotentialAmmount": 150000,"EarnedAmmount": 200000}, { 
     "keyword": "Feb","PotentialAmmount": 250000,"EarnedAmmount": 100000}, { 
     "keyword": "Mar","PotentialAmmount": 450000,"EarnedAmmount": 100000}]; 

我想補充PotentialAmmount和data2在JavaScript data1EarnedAmmount但我不知道怎麼樣。

Answer 1

如果我明白你的問題吧，你想要的功能是：

data3 = data1.map(function(obj, i) { 
    var sum = {}; 
    for (var key in obj) { 
    sum[key] = typeof obj[key] === 'number' ? obj[key] + data2[i][key] : obj[key]; 
    } 
    return sum; 
}); 

這將使新的對象數據3，將有多個字段相同的數據結構和總和。如果你需要檢查關鍵字，邏輯將會更復雜一點。
