React 实现考勤表

数据结构设计

考勤表通常需要记录员工、日期和考勤状态。可以使用以下数据结构：

const attendanceData = [
  {
    id: 1,
    name: "张三",
    records: [
      { date: "2023-10-01", status: "present" },
      { date: "2023-10-02", status: "absent" }
    ]
  }
];

组件结构

创建三个主要组件：

AttendanceTable：主表格组件
EmployeeRow：处理单行员工数据
StatusCell：渲染单个考勤状态单元格

function AttendanceTable({ data }) {
  return (
    <table>
      <thead>
        <tr>
          <th>姓名</th>
          <th>日期1</th>
          <th>日期2</th>
        </tr>
      </thead>
      <tbody>
        {data.map(employee => (
          <EmployeeRow key={employee.id} employee={employee} />
        ))}
      </tbody>
    </table>
  );
}

状态管理

使用React状态管理考勤数据：

const [attendance, setAttendance] = useState(initialData);

const updateStatus = (employeeId, date, newStatus) => {
  setAttendance(prev => prev.map(emp => {
    if(emp.id === employeeId) {
      return {
        ...emp,
        records: emp.records.map(rec => 
          rec.date === date ? {...rec, status: newStatus} : rec
        )
      };
    }
    return emp;
  }));
};

可视化呈现

为不同状态添加样式：

.present { background-color: #a3e635; }
.absent { background-color: #f87171; }
.leave { background-color: #60a5fa; }

完整示例

function StatusCell({ status, onUpdate }) {
  const colors = {
    present: 'bg-green-300',
    absent: 'bg-red-300',
    leave: 'bg-blue-300'
  };

  return (
    <td 
      className={`p-2 ${colors[status]}`}
      onClick={onUpdate}
    >
      {status}
    </td>
  );
}

function AttendanceApp() {
  const [data, setData] = useState(attendanceData);

  const handleStatusChange = (employeeId, date) => {
    const statusOptions = ['present', 'absent', 'leave'];
    const employee = data.find(e => e.id === employeeId);
    const currentIndex = statusOptions.indexOf(
      employee.records.find(r => r.date === date).status
    );
    const nextStatus = statusOptions[(currentIndex + 1) % statusOptions.length];

    setData(prev => prev.map(emp => {
      if(emp.id === employeeId) {
        return {
          ...emp,
          records: emp.records.map(rec => 
            rec.date === date ? {...rec, status: nextStatus} : rec
          )
        };
      }
      return emp;
    }));
  };

  return (
    <div className="p-4">
      <AttendanceTable 
        data={data} 
        onStatusChange={handleStatusChange}
      />
    </div>
  );
}
