scrollTo(目标，选项)在移动设备中不起作用。(火车头卷轴)

// 示例：移除触摸事件监听器
document.removeEventListener('touchmove', preventDefault, { passive: false });

/* 示例：调整 CSS 样式 */
.scrollable-element {
  overflow: auto;
  position: relative;
}

// 示例：使用 requestAnimationFrame
function smoothScrollTo(element, to, duration) {
  const start = element.scrollTop;
  const change = to - start;
  let currentTime = 0;
  const increment = 20;

  function animateScroll() {
    currentTime += increment;
    const val = Math.easeInOutQuad(currentTime, start, change, duration);
    element.scrollTop = val;
    if (currentTime < duration) {
      requestAnimationFrame(animateScroll);
    }
  }

  animateScroll();
}

// 缓动函数
Math.easeInOutQuad = function(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;
};

// 示例：确保 DOM 元素已加载
document.addEventListener('DOMContentLoaded', () => {
  const element = document.getElementById('targetElement');
  element.scrollTo({
    top: 100,
    behavior: 'smooth'
  });
});
