JavaScript实现人事管理系统

下面是一个基于JavaScript的简单人事管理系统实现方案，包含核心功能和代码示例：

核心功能模块

class Employee {
  constructor(id, name, department, position, salary) {
    this.id = id;          // 员工ID
    this.name = name;      // 姓名
    this.department = department;  // 部门
    this.position = position;      // 职位
    this.salary = salary;  // 薪资
  }
}

class HRSystem {
  constructor() {
    this.employees = [];   // 员工数据库
    this.nextId = 1;       // 自增ID计数器
  }

  // 添加新员工
  addEmployee(name, department, position, salary) {
    const newEmployee = new Employee(
      this.nextId++,
      name,
      department,
      position,
      salary
    );
    this.employees.push(newEmployee);
    return newEmployee;
  }

  // 删除员工
  removeEmployee(id) {
    const index = this.employees.findIndex(emp => emp.id === id);
    if (index !== -1) {
      return this.employees.splice(index, 1)[0];
    }
    return null;
  }

  // 更新员工信息
  updateEmployee(id, updateData) {
    const employee = this.employees.find(emp => emp.id === id);
    if (employee) {
      Object.assign(employee, updateData);
      return employee;
    }
    return null;
  }

  // 查询员工
  findEmployee(criteria) {
    return this.employees.filter(emp => 
      Object.keys(criteria).every(key => 
        emp[key] === criteria[key]
      )
    );
  }

  // 生成部门报告
  generateDepartmentReport() {
    const report = {};
    this.employees.forEach(emp => {
      if (!report[emp.department]) {
        report[emp.department] = { count: 0, totalSalary: 0 };
      }
      report[emp.department].count++;
      report[emp.department].totalSalary += emp.salary;
    });
    return report;
  }
}

使用示例

// 初始化系统
const myHR = new HRSystem();

// 添加员工
myHR.addEmployee("张三", "技术部", "前端工程师", 15000);
myHR.addEmployee("李四", "技术部", "后端工程师", 18000);
myHR.addEmployee("王五", "市场部", "营销经理", 20000);

// 更新员工信息
myHR.updateEmployee(2, { position: "高级工程师", salary: 22000 });

// 查询技术部员工
const techDept = myHR.findEmployee({ department: "技术部" });
console.log("技术部员工:", techDept);

// 生成部门报告
const report = myHR.generateDepartmentReport();
console.log("部门统计报告:", report);

// 删除员工
myHR.removeEmployee(3);
console.log("删除后剩余员工:", myHR.employees);

功能扩展建议

数据持久化：添加localStorage支持

saveToLocalStorage() {
  localStorage.setItem('hrData', JSON.stringify({
    employees: this.employees,
    nextId: this.nextId
  }));
}

loadFromLocalStorage() {
  const data = JSON.parse(localStorage.getItem('hrData'));
  if (data) {
    this.employees = data.employees;
    this.nextId = data.nextId;
  }
}

薪资计算功能：

calculatePayroll() {
  return this.employees.reduce((total, emp) => total + emp.salary, 0);
}

工龄跟踪：

class Employee {
  constructor(/*...*/ joinDate = new Date()) {
    // ...
    this.joinDate = joinDate;
  }

  getYearsOfService() {
    const diff = new Date() - this.joinDate;
    return Math.floor(diff / (1000 * 60 * 60 * 24 * 365));
  }
}
