在 JavaScript 中比較數(shù)組和嵌套數(shù)組

JavaScript

慕村9548890 2023-08-18 16:35:46

我有兩個數(shù)組，一個是accounts，另一個是departments。要求：-> 需要比較兩個數(shù)組并需要獲取過濾后的帳戶數(shù)組。-> 帳戶數(shù)組是單級的，而部門數(shù)組有兩級，我需要比較JobTitleID帳戶和部門中的值。-> 最后返回修改后的賬戶數(shù)組以及過濾后的數(shù)據(jù)。const accounts = [ { "AccountId": 25205, "CandidateID": 8474, "JobTitleID": 250 }, { "AccountId": 25206, "CandidateID": 8474, "JobTitleID": 253 }, { "AccountId": 25232, "CandidateID": 8474, "JobTitleID": 257 }, { "AccountId": 25233, "CandidateID": 8474, "JobTitleID": 261 }, { "AccountId": 25236, "CandidateID": 8474, "JobTitleID": 256 }, { "AccountId": 25237, "CandidateID": 8474, "JobTitleID": 255 }, { "AccountId": 25245, "CandidateID": 8474, "JobTitleID": 281 }, { "AccountId": 25246, "CandidateID": 8474, "JobTitleID": 279 }, { "AccountId": 25265, "CandidateID": 8474, "JobTitleID": 362 }]const departments = [ { "deptName": "Production", "jobTitles": [ { "JobTitleID": 246, "DepartmentID": 72, "JobName": "Department Foreman" }, { "JobTitleID": 357, "DepartmentID": 72, "JobName": "Maintenance Supervisor" }, { "JobTitleID": 247, "DepartmentID": 72, "JobName": "Production Manager" }, { "JobTitleID": 362, "DepartmentID": 72, "JobName": "Safety & Compliance Supervisor" } ] }, { "deptName": "Engineering", "jobTitles": [ { "JobTitleID": 250, "DepartmentID": 73, "JobName": "Architect" }, { "JobTitleID": 248, "DepartmentID": 73, "JobName": "CAD Operator" }, { "JobTitleID": 249, "DepartmentID": 73, "JobName": "Engineering Manager" }, { "JobTitleID": 251, "DepartmentID": 73, "JobName": "Professional Engineer" } ] },

您可以創(chuàng)建數(shù)組中所有作業(yè)的數(shù)組departments，然后accounts使用過濾數(shù)組.some(..)來檢查先前生成的數(shù)組中是否存在特定作業(yè)。這是一個例子：

const accounts = [

{

"AccountId": 25205,

"CandidateID": 8474,

"JobTitleID": 250

},

{

"AccountId": 25206,

"CandidateID": 8474,

"JobTitleID": 253

},

{

"AccountId": 25232,

"CandidateID": 8474,

"JobTitleID": 257

},

{

"AccountId": 25233,

"CandidateID": 8474,

"JobTitleID": 261

},

{

"AccountId": 25236,

"CandidateID": 8474,

"JobTitleID": 256

},

{

"AccountId": 25237,

"CandidateID": 8474,

"JobTitleID": 255

},

{

"AccountId": 25245,

"CandidateID": 8474,

"JobTitleID": 281

},

{

"AccountId": 25246,

"CandidateID": 8474,

"JobTitleID": 279

},

{

"AccountId": 25265,

"CandidateID": 8474,

"JobTitleID": 362

}

]

const departments = [

{

"deptName": "Production",

"jobTitles": [

{

"JobTitleID": 246,

"DepartmentID": 72,

"JobName": "Department Foreman"

},

{

"JobTitleID": 357,

"DepartmentID": 72,

"JobName": "Maintenance Supervisor"

},

{

"JobTitleID": 247,

"DepartmentID": 72,

"JobName": "Production Manager"

},

{

"JobTitleID": 362,

"DepartmentID": 72,

"JobName": "Safety & Compliance Supervisor"

}

]

},

{

"deptName": "Engineering",

"jobTitles": [

{

"JobTitleID": 250,

"DepartmentID": 73,

"JobName": "Architect"

},

{

"JobTitleID": 248,

"DepartmentID": 73,

"JobName": "CAD Operator"

},

{

"JobTitleID": 249,

"DepartmentID": 73,

"JobName": "Engineering Manager"

},

{

"JobTitleID": 251,

"DepartmentID": 73,

"JobName": "Professional Engineer"

}

]

},

{

"deptName": "Purchasing",

"jobTitles": [

{

"JobTitleID": 253,

"DepartmentID": 74,

"JobName": "Purchasing Agent"

},

{

"JobTitleID": 255,

"DepartmentID": 74,

"JobName": "Purchasing Manager"

},

{

"JobTitleID": 252,

"DepartmentID": 74,

"JobName": "Yard Foreman"

}

]

}

]

const jobs = departments.reduce((a, c) => (a.concat(c.jobTitles)), []);

const results = accounts.filter(account => jobs.some(job => job.JobTitleID === account.JobTitleID));

console.log(results);

您可以使用獲得優(yōu)化解決方案Set object。Set 對象僅存儲任何類型的唯一值。首先，使用數(shù)組中的 set 對象獲取所有唯一的 JobTitleID departments。然后使用Array.prototype.filter()方法對accounts數(shù)組進(jìn)行過濾即可得到結(jié)果。

const accounts = [

{

AccountId: 25205,

CandidateID: 8474,

JobTitleID: 250,

},

{

AccountId: 25206,

CandidateID: 8474,

JobTitleID: 253,

},

{

AccountId: 25232,

CandidateID: 8474,

JobTitleID: 257,

},

AccountId: 25233,

CandidateID: 8474,

JobTitleID: 261,

},

{

AccountId: 25236,

CandidateID: 8474,

JobTitleID: 256,

},

{

AccountId: 25237,

CandidateID: 8474,

JobTitleID: 255,

},

{

AccountId: 25245,

CandidateID: 8474,

JobTitleID: 281,

},

{

AccountId: 25246,

CandidateID: 8474,

JobTitleID: 279,

},

{

AccountId: 25265,

CandidateID: 8474,

JobTitleID: 362,

},

];

const departments = [

{

deptName: 'Production',

jobTitles: [

{

JobTitleID: 246,

DepartmentID: 72,

JobName: 'Department Foreman',

},

{

JobTitleID: 357,

DepartmentID: 72,

JobName: 'Maintenance Supervisor',

},

{

JobTitleID: 247,

DepartmentID: 72,

JobName: 'Production Manager',

},

{

JobTitleID: 362,

DepartmentID: 72,

JobName: 'Safety & Compliance Supervisor',

},

],

},

{

deptName: 'Engineering',

jobTitles: [

{

JobTitleID: 250,

DepartmentID: 73,

JobName: 'Architect',

},

{

JobTitleID: 248,

DepartmentID: 73,

JobName: 'CAD Operator',

},

{

JobTitleID: 249,

DepartmentID: 73,

JobName: 'Engineering Manager',

},

{

JobTitleID: 251,

DepartmentID: 73,

JobName: 'Professional Engineer',

},

],

},

{

deptName: 'Purchasing',

jobTitles: [

{

JobTitleID: 253,

DepartmentID: 74,

JobName: 'Purchasing Agent',

},

{

JobTitleID: 255,

DepartmentID: 74,

JobName: 'Purchasing Manager',

},

{

JobTitleID: 252,

DepartmentID: 74,

JobName: 'Yard Foreman',

},

],

},

];

const set = new Set();

departments.forEach((x) => x.jobTitles.forEach((y) => set.add(y.JobTitleID)));

const ret = accounts.filter((x) => set.has(x.JobTitleID));

console.log(ret);
