移动端滚动卡顿问题修复方案

问题背景

页面包含多个不同高度的区块，通过transform实现滑入滑出显示/隐藏，未显示区块通过-translate-x-full移出视口。PC端运行正常，但移动端滚动时会卡在顶部/底部附近，需松开后再次滚动才能到位，新建项目初期正常但很快复发。

问题根源

容器设置的h-screen overflow-hidden与移动端原生滚动手势处理产生冲突；
未显示的绝对定位区块虽被平移，但仍会响应触摸事件，干扰当前显示区块的滚动逻辑；
可滚动区块未明确指定触摸滚动行为，导致浏览器手势识别混乱。

修复方案

1. 添加触摸滚动优化样式

在自定义样式中补充：

.slide {
  transition: transform 0.5s ease-in-out;
}
/* 优化移动端触摸滚动 */
.scrollable-slide {
  touch-action: pan-y;
}
/* 隐藏区块禁用事件响应 */
.hidden-slide {
  pointer-events: none;
}

2. 修改区块类名配置

给可滚动的page2添加scrollable-slide类，初始状态下给未显示区块添加hidden-slide类：

<!-- 2nd Page - Question Page -->
<div
  id="page2"
  class="slide absolute inset-0 flex flex-col justify-start items-center bg-white text-center p-6 transform -translate-x-full overflow-y-auto scrollable-slide hidden-slide"
>
<!-- 其他未显示区块同步添加hidden-slide -->
<div
  id="page3"
  class="slide absolute inset-0 flex flex-col justify-center items-center bg-gray-200 p-8 transform -translate-x-full hidden-slide"
>
<div
  id="page4"
  class="slide absolute inset-0 flex justify-center items-center bg-green-500 text-white text-center transform -translate-x-full hidden-slide"
>

3. 更新JavaScript切换逻辑

切换页面时同步添加/移除hidden-slide类，确保隐藏区块不响应事件：

function goToPage2() {
  document.getElementById("page1").classList.add("transform", "-translate-x-full", "hidden-slide");
  document.getElementById("page2").classList.remove("transform", "-translate-x-full", "hidden-slide");
}

function goToPage3() {
  document.getElementById("page2").classList.add("transform", "-translate-x-full", "hidden-slide");
  document.getElementById("page3").classList.remove("transform", "-translate-x-full", "hidden-slide");
}

document.getElementById("form").addEventListener("submit", function (event) {
  event.preventDefault();
  document.getElementById("page3").classList.add("transform", "-translate-x-full", "hidden-slide");
  document.getElementById("page4").classList.remove("transform", "-translate-x-full", "hidden-slide");
});

关键修复点说明

touch-action: pan-y：明确告诉移动端浏览器只处理垂直滚动手势，避免与滑入滑出的transform动画产生手势冲突；
pointer-events: none：让隐藏区块完全不接收触摸、鼠标等交互事件，彻底排除其对当前显示区块滚动的干扰；
同步切换hidden-slide类：确保每次页面切换时，只有当前显示的区块处于可交互状态。
