動態插入的JavaScript

Question

我已經像對象的數組定義的數據：

{"Driver":a, "Lap":b, "Position":c} 

我想和一個循環相同的行中插入每圈（成另一數據）中的所有驅動器。例如：

 {"Lap":1,"Driver1":2,"Driver2":1,"Driver3":3} 
     {"Lap":2,"Driver1":1,"Driver2":2,"Driver3":3} 
     {"Lap":3,"Driver1":3,"Driver2":2,"Driver3":1}  
     {"Lap":4,"Driver1":2,"Driver2":1,"Driver3":3} 

我知道圈數（變量maxLaps）和變量numDrivers上的驅動程序的數量。

我想要在一個循環，因爲圈和驅動程序的數量在不同情況下的變化，所以我需要做我的代碼一般

Answer 1

定義一個JavaScript對象，如：

var myObject = { "Driver": a, "Lap": b, "Position": c }; 

新的屬性添加到該對象爲：

myObject.newProperty = d; // now you have: { "Driver": a, "Lap": b, "Position": c, "newProperty": d } 

添加動態屬性爲：

myObject[dynamicProperty] = e; // now if your dynamic property is 'test', your object is: { "Driver": a, "Lap": b, "Position": c, "newProperty": d, "test": e }
