我有一个对象包含许多键值对记录的JSON数组，但是我只需要几个键记录。如何使用键创建新数组？
array = [
{
airlineName: "Airline 1",
hotelName: "Hotel 1 ",
airportId: "456",
checkInDate: "17 SEP 1998",
bookingStatus: "B"
},
{
airlineName: "Airline 2",
hotelName: "Hotel 1",
airportId: "123",
checkInDate: "7 AUG 1998",
bookingStatus: "P"
}
]
我想要这样的数组进行一些操作：
array = [
{
airlineName: "Airline 1",
hotelName: "Hotel 1 ",
bookingStatus: "B"
},
{
airlineName: "Airline 2",
hotelName: "Hotel 1",
bookingStatus: "P"
}
]
单线工作解决方案：
this.array.map(x => ({airlineName: x.airlineName, hotelName: x.hotelName, bookingStatus: x.bookingStatus}))
