javascript - 根据数组条件进行过滤

Question

假设我有一个 userId 数组

const userIds = ['1234', '3212', '1122']

然后我有一个对象数组

const arrayOfObjects = [
  {
    _source: {itemId: ['1234'] }
  },
  {
    _source: {itemId: ['3212'] }
  },
  {
    _source: {itemId: ['1111'] }
  }
]

我想通过将 id 与 userIds 数组匹配来过滤对象数组

arrayOfObjects.filter(item => item._source.itemId === "这里放什么？")

Answer 1

试试这个

arrayOfObjects.filter(item => userIds.includes(item._source.itemId[0]))
