js关闭所有定时器

// 存储所有定时器ID的数组
let timers = [];

// 封装setTimeout，记录定时器ID
function mySetTimeout(callback, delay) {
    const timerId = setTimeout(() => {
        callback();
        // 执行完毕后移除定时器ID
        timers = timers.filter(id => id !== timerId);
    }, delay);
    timers.push(timerId);
    return timerId;
}

// 封装setInterval，记录定时器ID
function mySetInterval(callback, delay) {
    const timerId = setInterval(callback, delay);
    timers.push(timerId);
    return timerId;
}

// 关闭所有定时器
function clearAllTimers() {
    timers.forEach(timerId => {
        if (timerId instanceof Number) {
            clearTimeout(timerId);
        } else {
            clearInterval(timerId);
        }
    });
    timers = [];
}

// 示例使用
mySetTimeout(() => console.log('Timeout 1'), 1000);
mySetInterval(() => console.log('Interval 1'), 2000);

// 5秒后关闭所有定时器
mySetTimeout(() => {
    console.log('Clearing all timers');
    clearAllTimers();
}, 5000);
