javascript - 根据值获取/过滤对象

Question

这个问题已经有答案了:

How to filter object array based on attributes? (21 个回答)

已关闭 6 年前。

我可以根据值过滤或提取对象的值吗？

例如 [10, 19] 将返回 Bill 和 Sam。

 [ { "id": 10, "nice_name": "Bill" }, 
    { "id": 12, "nice_name": "Dan"}, 
    { "id": 18, "nice_name": "Tony" },
    { "id": 19, "nice_name": "Sam" }, 
]

谢谢/

您可以链接过滤器然后映射函数:

const mySearch = [10, 19]
const result = myArray.filter(elem => mySearch.indexOf(elem.id) > -1) // filter by id
                      .map(elem => elem.nice_name) // return the nice_name only for each entry
// result is now ['Bill', 'Sam']
