在react中过滤对象数组不工作

Question

我有一个对象数组，如下所示:

0: {Id: 1, name: 'xyz', pqID: 10, pqType: null}
1: {Id: 2, name: 'abc', pqID: 15, pqType: null}
2: {Id: 3, name: 'wer', pqID: 16, pqType: null}
3: {Id: 4, name: 'uyt', pqID: 18, pqType: null}
4: {Id: 5, name: 'qwe', pqID: 22, pqType: null}
5: {Id: 6, name: 'ert', pqID: 25, pqType: null}

我想要pqID, 10和15的对象。下面是我正在尝试的，它给出了空数组:

const newUsers = arr.filter(
(user) => user.pqID == 10 && user.pqID == 15
);
console.log(newUsers);

Answer 1

你可以试试，用完整的数组函数语法:

const newUsers = arr.filter(
(user) => {return [10, 15].includes(user.pqID)}
);

或者不带括号和花括号的简化版本:

const newUsers = arr.filter(user => [10, 15].includes(user.pqID));

Answer 2

注意||操作符

var arr = 
[{Id: 1, name: 'xyz', pqID: 10, pqType: null},
{Id: 2, name: 'abc', pqID: 15, pqType: null},
{Id: 3, name: 'wer', pqID: 16, pqType: null},
{Id: 4, name: 'uyt', pqID: 18, pqType: null},
{Id: 5, name: 'qwe', pqID: 22, pqType: null},
{Id: 6, name: 'ert', pqID: 25, pqType: null}]
const newUsers = arr.filter(
(user) =>
user.pqID == 10 || user.pqID == 15 // note ||
);
console.log(newUsers)
