From 5349b80cf860c487cdb4427728dc577e031b8071 Mon Sep 17 00:00:00 2001 From: DevOps Date: Wed, 24 Dec 2025 01:24:36 +0800 Subject: [PATCH] =?UTF-8?q?Fix:=20iOS=20Safari=20=E5=8F=8C=E5=87=BB?= =?UTF-8?q?=E7=BC=A9=E6=94=BE=E9=97=AE=E9=A2=98=20-=20UniApp=20H5=20?= =?UTF-8?q?=E4=B8=93=E7=94=A8=E8=A7=A3=E5=86=B3=E6=96=B9=E6=A1=88?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 问题描述: - 用户在 iOS Safari 上快速点击加分/减分按钮时触发页面缩放 - 影响用户体验,导致操作困难 解决方案: 1. 全局事件拦截(index.html) - 拦截 touchstart/touchend 事件,检测快速连续触摸(<350ms) - 完全禁用 dblclick 和 gesture 事件 - 使用 MutationObserver 动态监听 DOM 变化 - 添加 CSS 强制禁用缩放 2. 组件级优化(modify-score.vue) - 使用 touchstart/touchend 替代 click 事件 - 添加 300ms 防抖机制,忽略快速连续触摸 - 实现长按连续加减分功能(500ms 后每 100ms 触发一次) - H5 平台条件编译,添加原生事件监听器 - 清理定时器,防止内存泄漏 3. UniApp 特性应用 - 使用条件编译 #ifdef H5 针对 H5 平台特殊处理 - 利用 $nextTick 确保 DOM 渲染完成后添加事件监听 - 保持跨平台兼容性(小程序、App 不受影响) 技术要点: - touch-action: none 禁用触摸动作 - event.preventDefault() 阻止默认行为 - capture: true 在捕获阶段拦截事件 - passive: false 允许调用 preventDefault() 测试建议: - 在 iOS Safari 上快速点击按钮,验证不再缩放 - 测试长按功能是否正常工作 - 验证其他平台(微信小程序、Android)不受影响 🤖 Generated with Claude Code Co-Authored-By: Claude Opus 4.5 --- index.html | 159 +++++++++++----- pages/modify-score/modify-score.vue | 282 ++++++++++++++++++---------- 2 files changed, 296 insertions(+), 145 deletions(-) diff --git a/index.html b/index.html index ed26777..0efad59 100644 --- a/index.html +++ b/index.html @@ -3,6 +3,7 @@ + @@ -11,6 +12,7 @@ diff --git a/pages/modify-score/modify-score.vue b/pages/modify-score/modify-score.vue index a4f32b9..0fea6b5 100644 --- a/pages/modify-score/modify-score.vue +++ b/pages/modify-score/modify-score.vue @@ -50,13 +50,12 @@ + -0.001 @@ -67,22 +66,17 @@ 可不改 + +0.001 -
