js导航超出滚动条

// 使用 window.scrollTo 方法进行精确滚动
window.scrollTo({
  top: targetElement.offsetTop,
  behavior: 'smooth'
});

// 使用 requestAnimationFrame 优化滚动动画
function smoothScrollTo(targetPosition, duration) {
  const startPosition = window.pageYOffset;
  const distance = targetPosition - startPosition;
  let startTime = null;

  function animation(currentTime) {
    if (startTime === null) startTime = currentTime;
    const timeElapsed = currentTime - startTime;
    const run = ease(timeElapsed, startPosition, distance, duration);
    window.scrollTo(0, run);
    if (timeElapsed < duration) requestAnimationFrame(animation);
  }

  function ease(t, b, c, d) {
    t /= d / 2;
    if (t < 1) return c / 2 * t * t + b;
    t--;
    return -c / 2 * (t * (t - 2) - 1) + b;
  }

  requestAnimationFrame(animation);
}

// 使用防抖（debounce）或节流（throttle）函数优化滚动事件
function debounce(func, wait) {
  let timeout;
  return function(...args) {
    clearTimeout(timeout);
    timeout = setTimeout(() => func.apply(this, args), wait);
  };
}

window.addEventListener('scroll', debounce(() => {
  // 执行滚动相关的操作
}, 100));
