javascript - 将某些行从一个对象移动到另一个对象的最佳方法

Question

只是想知道使用数组将数据从一个对象过滤到另一个对象的最佳方法是什么

我想将 selected_city_codes 中的整行从 airport_data_1 移至 airport_data_2

airport_data_1 = [{"departure_time":"12:00","arrival_time":"03:00","city_id":"BOS"},  
{"departure_time" :"12:00","arrival_time":"03:00","city_id":"BOS"},
{"departure_time" :"01:00","arrival_time":"04:00","city_id":"SFO"},
{"departure_time" :"03:00","arrival_time":"05:00","city_id":"BOS"},
{"departure_time" :"03:00","arrival_time":"05:00","city_id":"SFO"},
{"departure_time" :"04:00","arrival_time":"06:00","city_id":"SJC"},
{"departure_time" :"04:00","arrival_time":"06:00","city_id":"JFK"},
{"departure_time" :"06:00","arrival_time":"09:00","city_id":"SJC"}];

airport_data_2 = [];

selected_city_codes = ['SJC','JFK']; //items to remove from `airport_data_1` to `airport_data_2`

//my attempt to remove the listed values from selected_city_codes
for(i in selected_city_codes) { 
    airport_data_2 = airport_data_2.filter(item => item.city_id != selected_city_codes[i]);
}

期望的结果

airport_data_1 = [{"departure_time":"12:00","arrival_time":"03:00","city_id":"BOS"},  
{"departure_time" :"12:00","arrival_time":"03:00","city_id":"BOS"},
{"departure_time" :"01:00","arrival_time":"04:00","city_id":"SFO"},
{"departure_time" :"03:00","arrival_time":"05:00","city_id":"BOS"},
{"departure_time" :"03:00","arrival_time":"05:00","city_id":"SFO"}]; 


airport_data_2 = [{"departure_time" :"04:00","arrival_time":"06:00","city_id":"SJC"},
{"departure_time" :"04:00","arrival_time":"06:00","city_id":"JFK"},
{"departure_time" :"06:00","arrival_time":"09:00","city_id":"SJC"}]; 

Answer 1

您必须过滤第一个数组并使用类似 includes 的内容来检查 city_id 是否在 selected_city_codes 中:

const airport_data_1 = [
  { departure_time: '12:00', arrival_time: '03:00', city_id: 'BOS' },
  { departure_time: '12:00', arrival_time: '03:00', city_id: 'BOS' },
  { departure_time: '01:00', arrival_time: '04:00', city_id: 'SFO' },
  { departure_time: '03:00', arrival_time: '05:00', city_id: 'BOS' },
  { departure_time: '03:00', arrival_time: '05:00', city_id: 'SFO' },
  { departure_time: '04:00', arrival_time: '06:00', city_id: 'SJC' },
  { departure_time: '04:00', arrival_time: '06:00', city_id: 'JFK' },
  { departure_time: '06:00', arrival_time: '09:00', city_id: 'SJC' },
];
const selected_city_codes = ['SJC', 'JFK'];

const airport_data_2 = airport_data_1.filter((el) =>
  selected_city_codes.includes(el.city_id)
);
console.log(airport_data_2);
