lodash.js select like mysqls `in`

Question

我正在使用lodash.js过滤我的json值。我需要像Lodash中的Mysqls " in“函数一样的东西。

json value:
[
{id:1,customer:5},{id:2,customer:6},{id:3,customer:6},{id:2,customer:7}
]

我想在lodash中选择"customer in(6,7)"。我该怎么做呢？

Answer 1

您可以在集合上使用lodashes filter函数。

​

const input = '[{"id":1,"customer":5},{"id":2,"customer":6},{"id":3,"customer":6},{"id":2,"customer":7}]';

const mysqlIn = (json, array) => {
  const data = JSON.parse(json);
  let ans = _.filter(data, function(x) {
    return array.includes(x.customer);
  });
  return ans;
}

console.log(mysqlIn(input, [6,7]));
