动态插入对象javascript

Question

我已将数据定义为对象数组：

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

我希望用一个循环在同一行中插入每一圈的所有驱动程序（转换为另一个数据）。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Laps的数量（在变量maxLaps中）和变量numDrivers上的驱动器数量。

我想在循环中制作它，因为不同情况下圈数和驱动程序的数量会发生变化，所以我需要将代码设为通用

Answer 1

定义一个Javascript对象，如：

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

将新属性添加到此对象：

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

添加动态属性：

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