我想在比较两个数组后 return true or false

Question

我想在比较两个数组后return真或假。

这里是第一个数组：

const permissionsArray = [
  {
    "groupName": "User",
    "permissions": [
      "Permissions.Users.View",
      "Permissions.Users.Create",
      "Permissions.Users.Edit",
      "Permissions.Users.Delete"
    ]
  }, {
    "groupName": "Role",
    "permissions": [
      "Permissions.Roles.View",
      "Permissions.Roles.Create",
      "Permissions.Roles.Edit",
      "Permissions.Roles.Delete"
    ]
  },
]

此处包含权限数组的对象：

const userPermissionArray = 
  {
    "id": "cdfda4d3-ea1a-4662-a611-2d2e52b772b0",
    "name": "ABP Manager",
    "description": "ABP Manager",
    "usersCount": 4,
    "isActive": false,
    "permissions": [
      "Permissions.Users.View",
      "Permissions.Users.Create",
      "Permissions.Users.Edit",
      "Permissions.Users.Delete"
    ]
  }

我想比较 [permissionsArray.permissions] 和 [userPermissionArray.permissions].

我试过了，但我失败了。我的代码在这里：

console.log(
  userPermissionArray.permissions
    .map(roleItem => roleItem === userPermissionArray
      .map(item  => item.permissions.map(item => item))
    )
);

我正在尝试 return 'true' 或 'false'。

Answer 1

您可以flat权限列表以便于比较，然后使用some功能检查是否存在任何条目

let flatPermissions = permissionsArray.map(e => e["permissions"]).flat();

let result = userPermissionArray.permissions.some(i => flatPermissions.includes(i));

console.log(result);

Answer 2

试着这样比较：

    let permissionsA = [
        "Permissions.Users.View",
        "Permissions.Users.Create",
        "Permissions.Users.Edit",
        "Permissions.Users.Delete"
    ]
    
    let permissionsB = [
        "Permissions.Users.View",
        "Permissions.Users.Create",
        "Permissions.Users.Edit",
    ]
    
    let rs = permissionsA.reduce((a, b) => {
        return {
            ...a,
            [b]: permissionsB.includes(b)
        }
    }, {})

    console.log(rs)

    
/*  
 {
  Permissions.Users.Create: true,
  Permissions.Users.Delete: false,
  Permissions.Users.Edit: true,
  Permissions.Users.View: true
 } */

我想在比较两个数组后 return true or false

I want to return true or false after comparing two arrays

javascript
