javascript - 通过Javascript中的角色数组过滤用户对象数组

问题描述

我有一组用户对象。我想根据用户角色数组过滤它们。

filter = ['ROLE_SELLER', 'ROLE_BANK', 'ROLE_CPF', 'ROLE_SLA', 'ROLE_LDAU']


const users = [{
		"id": 1,
		"email": "user1@test.com",
		"name": "User1",
		"roles": [{
				"id": 1,
				"code": "ROLE_ADMINISTRATOR",
				"name": "Administrator"
			},
			{
				"id": 2,
				"code": "ROLE_SELLER",
				"name": "Seller"

			}
		]
	}, {
		"id": 2,
		"email": "user2@test.com",
		"name": "User2",
		"roles": [{
			"id": 1,
			"code": "ROLE_ADMINISTRATOR",
			"name": "Administrator"
		}]
	}, {
		"id": 3,
		"email": "user3@test.com",
		"name": "User3",
		"roles": [{
			"id": 1,
			"code": "ROLE_ADMINISTRATOR",
			"name": "Administrator"
		}]
	}, {
		"id": 4,
		"email": "user4@test.com",
		"name": "User4",
		"roles": [{
				"id": 1,
				"code": "ROLE_ADMINISTRATOR",
				"name": "Administrator"
			},
			{
				"id": 2,
				"code": "ROLE_SELLER",
				"name": "Seller"

			}
		]
	}, {
		"id": 5,
		"email": "user5@test.com",
		"name": "User5",
		"roles": [{
			"id": 5,
			"code": "ROLE_LAWYER",
			"name": "Lawyer"

		}]
	}, {
		"id": 6,
		"email": "user6@test.com",
		"name": "User6",
		"roles": [{
			"id": 2,
			"code": "ROLE_SELLER",
			"name": "Seller"

		}]
	},
	{
		"id": 7,
		"email": "user7@test.com",
		"name": "User7",
		"roles": [{
			"id": 9,
			"code": "ROLE_SLA",
			"name": "sla"
		}]
	},
	{
		"id": 8,
		"email": "user8@test.com",
		"name": "User8",
		"roles": [{
			"id": 8,
			"code": "ROLE_BANK",
			"name": "Bank"

		}]
	},
	{
		"id": 9,
		"email": "user9@test.com",
		"name": "User9",
		"roles": [{
			"id": 7,
			"code": "ROLE_CPF",
			"name": "CPF"
		}]
	}
]
const filter = ['ROLE_SELLER', 'ROLE_BANK', 'ROLE_CPF', 'ROLE_SLA', 'ROLE_LDAU']

const filteredUsers = users.filter(user => !user.roles.find(role => filter.includes(role.id)))

console.log(filteredUsers)

预期结果

 [{
        "id": 1,
        "email": "user1@test.com",
        "name": "User1",
        "roles": [{
                "id": 1,
                "code": "ROLE_ADMINISTRATOR",
                "name": "Administrator"
            },
            {
                "id": 2,
                "code": "ROLE_SELLER",
                "name": "Seller"

            }
        ]
    }, {
        "id": 4,
        "email": "user4@test.com",
        "name": "User4",
        "roles": [{

            },
            {
                "id": 2,
                "code": "ROLE_SELLER",
                "name": "Seller"

            }
        ]
    }, {
        "id": 6,
        "email": "user6@test.com",
        "name": "User6",
        "roles": [{
            "id": 2,
            "code": "ROLE_SELLER",
            "name": "Seller"

        }]
    },
    {
        "id": 7,
        "email": "user7@test.com",
        "name": "User7",
        "roles": [{
            "id": 9,
            "code": "ROLE_SLA",
            "name": "sla"
        }]
    },
    {

        "roles": [{

        }]
    },
    {
        "id": 9,
        "email": "user9@test.com",
        "name": "User9",
        "roles": [{

            "code": "ROLE_CPF",
            "name": "CPF"
        }]
    }
 ]

解决方案

我试图想象你想要得到什么结果......

您想通过具有可能角色的数组过滤用户，如果用户具有过滤器数组的角色之一，您想将他的角色传递给“filteredUsers”数组？

filter.includes(role.id) - 我猜是错的，可能你想按 role.code 过滤？

Array.find() 不支持资源管理器 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find

Array.includes() - 也不支持 Explorer。 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes
