javascript - 使用键数组过滤对象数组[逆]

Question

我有以下键数组:

var keys = [{userId: "333"}, {userId: "334"}]

这个对象数组:

var users = [
{id: "333", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "334", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "335", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "336", firstName: "", lastName: "", idCard: "", birthDate: ""}
]

我需要通过使用我的keys Array过滤来更改我的users Array[相反结果]。

想不通，求所有答案! (js、jquery、 Angular )

有人吗？

Answer 1

您可以使用filter()和find()。

var users = [
{id: "333", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "334", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "335", firstName: "", lastName: "", idCard: "", birthDate: ""},
{id: "336", firstName: "", lastName: "", idCard: "", birthDate: ""}
]
var keys = [{userId: "333"}, {userId: "334"}]

var result = users.filter(function(o) {
  return !keys.find(function(e) {
    return e.userId == o.id
  })
})

console.log(result)
