如何建立个人任务管理系统？手把手4步教程（附模板）

// 任务收集器示例代码
class TaskCollector {
  constructor() {
    this.tasks = [];
    this.categories = ['工作', '个人', '学习', '健康'];
  }
  
  // 添加新任务
  addTask(title, category, priority = '中等') {
    const task = {
      id: Date.now(),
      title,
      category,
      priority,
      createdAt: new Date(),
      completed: false
    };
    this.tasks.push(task);
    return task;
  }
  
  // 获取所有未完成任务
  getPendingTasks() {
    return this.tasks.filter(task => !task.completed);
  }
}

// 使用示例
const myCollector = new TaskCollector();
myCollector.addTask('完成项目报告', '工作', '高');
myCollector.addTask('健身房锻炼', '健康', '中等');

-- 任务优先级管理表结构
CREATE TABLE tasks (
    id INT PRIMARY KEY AUTO_INCREMENT,
    title VARCHAR(255) NOT NULL,
    description TEXT,
    category VARCHAR(50),
    priority ENUM('低', '中等', '高', '紧急') DEFAULT '中等',
    due_date DATE,
    estimated_time INT COMMENT '预计耗时（分钟）',
    status ENUM('待办', '进行中', '已完成', '已推迟') DEFAULT '待办',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

-- 查询高优先级任务
SELECT * FROM tasks 
WHERE priority IN ('高', '紧急') 
AND status = '待办'
ORDER BY due_date ASC;

// 任务管理系统核心模型
public class TaskItem
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public TaskPriority Priority { get; set; }
    public TaskCategory Category { get; set; }
    public DateTime? DueDate { get; set; }
    public int EstimatedMinutes { get; set; }
    public TaskStatus Status { get; set; }
    public DateTime CreatedAt { get; set; }
    public DateTime UpdatedAt { get; set; }
}

public enum TaskPriority
{
    Low,
    Medium,
    High,
    Urgent
}

public enum TaskStatus
{
    Pending,
    InProgress,
    Completed,
    Deferred
}

// 任务调度服务
public class TaskSchedulerService
{
    public List ScheduleDailyTasks(List tasks, 
        int availableMinutes)
    {
        return tasks
            .Where(t => t.Status == TaskStatus.Pending)
            .OrderByDescending(t => t.Priority)
            .ThenBy(t => t.DueDate)
            .TakeWhile(t => availableMinutes -= t.EstimatedMinutes >= 0)
            .ToList();
    }
}
