Question

我有一个数组，我想根据多个值对其进行过滤：

let books= [{ bookId : 1},{ bookId : 3},{ bookId : 4},{ bookId : 7},{ bookId : 10}];
let searchValues= [1,7];
let newArray = [];

我可以像下面这样使用散布运算符：

searchValues.map(book=> {
  newArray.push(...books.filter(f => f.bookId== book.id));
});

但是有一种方法可以使用像这样或类似的东西衬里来过滤阵列？：

newArray = books.filter(f => f.bookId in values);

谢谢。

使用.includes

newArray = books.filter(f => values.includes(f.bookId))

let books = [
  { bookId: 1 },
  { bookId: 3 },
  { bookId: 4 },
  { bookId: 7 },
  { bookId: 10 },
]
let searchValues = [1, 7]
let newArray = []

newArray = books.filter((f) => searchValues.includes(f.bookId))

console.log(newArray)
