JS:鼠标空闲时自动滚动，手指不触摸？

let idleTime = 0;
const idleInterval = setInterval(timerIncrement, 1000); // 每秒检查一次
const scrollInterval = 5000; // 5秒后开始自动滚动

function timerIncrement() {
    idleTime++;
    if (idleTime >= scrollInterval / 1000) {
        autoScroll();
    }
}

function resetTimer() {
    idleTime = 0;
}

function autoScroll() {
    window.scrollBy(0, 100); // 每次滚动100像素
    setTimeout(autoScroll, 1000); // 每秒滚动一次
}

document.addEventListener('mousemove', resetTimer);
document.addEventListener('mousedown', resetTimer);
document.addEventListener('mouseup', resetTimer);
document.addEventListener('keypress', resetTimer);

function autoScroll() {
    window.scrollBy(0, 100);
    requestAnimationFrame(autoScroll);
}

let isTouching = false;

document.addEventListener('touchstart', () => {
    isTouching = true;
});

document.addEventListener('touchend', () => {
    isTouching = false;
});

function autoScroll() {
    if (!isTouching) {
        window.scrollBy(0, 100);
        requestAnimationFrame(autoScroll);
    }
}
