给键值添加相同的键名 + 给键值添加不同的键名

var rJson = {}
        rJson.Status = this.roomStatus
        var list = this.changeStatusRoomNos.split(',')
        rJson.RoomList = []
        list.forEach(element => {
        var obj = {}
        obj['RoomNo'] = element
        rJson.RoomList.push(obj)
})

var rs = [],arr = [1,2,3,4],arr2 = [a,b,c,d],key=['id','name'];
rs = arr.map(function(item,index){
    var obj ={};
    obj[key[0]] = arr[index];
    obj[key[1]] = arr2[index];
    return obj;
});
console.log(rs);
