🚀 从“更优”到“更智”：V5.7.3 的交互革新、模式扩展与体验跃迁
在 V5.6.4 版本实现了“化繁为简，聚焦核心”的目标后，我们收到了许多宝贵的用户反馈。本次 V5.7.3 版本，我们以“交互更流畅、功能更智能、体验更沉浸”为核心，对系统进行了一次全面的体验升级。我们不仅修复了已知问题，更引入了全新的抽取模式和交互方式，让您的每一次抽取都充满惊喜。
🎯 1. 全新“批量抽取”模式（全新功能）
痛点解决： 当您需要一次性选出多名学生（如小组代表、活动参与者）时，使用“连抽”模式需要多次点击，操作繁琐且结果分散。
全新进化： 隆重推出“批量抽取”模式！
- 一键抽取，结果清晰： 在“抽取设置”区域，您可以直接设置需要抽取的人数（如 3 人、5 人）。
- 不重复保证： 系统会一次性为您抽取指定数量的、不重复的学号，并将它们作为一个完整的批次结果展示在历史记录中。
- 场景丰富： 无论是组建学习小组、分配课堂任务，还是评选优秀代表，批量抽取都能让您高效、公平地完成任务。
🎮 2. 智能“连抽”模式全面升级（全新优化）
痛点解决： 旧版“连抽”模式仅是单次抽取的简单重复，缺乏视觉冲击力和仪式感。
全新进化： “连抽”模式现已全面重制，带来沉浸式全屏动态效果！
- 全屏动态展示： 点击“连抽”按钮后，系统将进入全屏模式，逐一、动态地展示每一次抽取的结果。
- 炫酷动画加持： 每个被抽中的学生姓名和学号都会伴随独特的动画（如翻转、弹入、滚动）出现，过程充满悬念与乐趣。
- 结果汇总： 抽取结束后，所有结果会自动汇总并添加到历史记录中，方便您回顾。
🔧 3. 交互革命：引入通用模态框系统（全新架构）
痛点解决： 旧版的确认弹窗功能单一，无法处理复杂的用户输入（如新建组名），且代码复用性差。
全新进化： 引入了通用、可复用的模态框（Modal）系统！
- 功能统一： 现在，“删除分组”、“清空名单”、“重置记录”、“新建组”、“重命名组”等所有需要用户确认或输入的操作，都使用了统一的模态框组件。
- 交互更佳： 模态框拥有半透明背景和模糊效果，视觉上更突出，交互体验更现代。输入框会自动聚焦，操作更流畅。
- 代码更优： 通过
showModalWithConfig方法，可以灵活配置模态框的标题、内容、按钮和回调函数，极大地提升了代码的可维护性和扩展性。
🎨 4. 主题与动画效果增强（体验优化）
痛点解决： 为庆祝功能和通知系统增添更多视觉细节，提升整体美观度。
全新进化： 细节之处见真章！
- 庆祝动画升级： 庆祝彩带（
confetti）的生成逻辑和动画效果得到优化，飘落更自然，色彩更丰富，将“全员抽取完毕”的喜悦感推向高潮。 - 通知系统完善： 通知消息（
notification）增加了图标和更明确的样式区分（成功/错误），信息传达更直观。 - 深色模式覆盖： 对模态框、通知等新增组件的深色模式支持进行了全面检查和适配，确保在任何主题下都拥有完美的视觉体验。
🔗 5. 配置持久化升级：URL参数新增权重同步（关键增强）
痛点解决： 之前的版本，您精心设置的概率权重无法通过链接分享，导致协作和远程教学时需要重新配置。
全新进化： 现在，概率权重设置已与URL参数完全同步！
- 完整配置共享： 您为不同学号范围设置的权重（如“1-10号权重80%”）会被自动编码并附加到当前页面的URL上。
- 一键分享，完美还原： 当您将此链接分享给同事或学生时，他们打开链接后，所有设置，包括复杂的概率权重，都会被完美还原。
- 无缝恢复： 即使您刷新页面，只要URL中包含参数，系统也会自动解析并应用这些设置，确保您的工作不丢失。
🐞 6. 核心逻辑与已知问题修复（稳定性提升）
- URL 参数解析修复： 修正了
noRepeat参数的解析逻辑，确保通过 URL 分享的链接能正确还原“不重复抽取”的开关状态。 - 概率权重逻辑微调： 优化了
getWeightedRandomNumber函数在边界条件下的处理，确保在极端设置下依然能稳定工作。 - 状态同步优化： 改进了
watch侦听器的配置，确保probabilityRanges等复杂对象的变化能更可靠地同步到 URL 和界面。
🎯 功能亮点总览
V5.7.3 版本在“更优”的基础上，实现了“更智”的飞跃，核心功能全面升级：
- ✅ 双模式操作： 灵活选择“学号范围”或“名单导入”模式。
- ✅ 多名单组管理： 支持创建、切换、删除多个独立的学生分组。
- ✅ 全新暗黑模式： 一键切换浅色/深色主题，保护您的眼睛。
- ✅ 多种抽取模式： 支持单次抽取、快速抽取（学号滚动）、连抽N次（带全屏特效）、批量抽取。
- ✅ 不重复抽取： 开启后，确保每个学号在本轮抽取中仅出现一次。
- ✅ 智能概率权重控制： 为不同学号区间设置不同的抽取概率，且支持通过URL完整分享和持久化。
- ✅ 精简字号设置： 移除字体选择，保留字号调节滑块，更加简洁高效。
- ✅ 沉浸式交互体验： “连抽”与“批量抽取”模式带来前所未有的动态视觉盛宴。
- ✅ 统一模态框系统： 所有确认与输入操作交互一致，体验更流畅。
- ✅ 数据持久化： 所有学生名单、分组、设置均自动保存，刷新不丢失。
- ✅ URL 参数同步： 所有配置（当前分组、学号范围、字体、主题、概率权重等）都会同步到 URL，方便分享与恢复。
- ✅ 拖拽上传： 支持将 Excel 文件直接拖拽到网页进行上传，操作更便捷。
💡 技术实现精要
本次更新在 main.js 和 style.css 中进行了关键重构与新增：
- 批量抽取实现：新增
drawBatchNumbers和drawBatchNumbersWithAnimation函数，利用getAllNumbers获取所有可选学号，结合noRepeat逻辑，一次性生成指定数量的不重复结果。 - 连抽模式重制：将
multiDraw逻辑与全新的全屏动态效果组件（multiEffectNumber,multiEffectName）结合，通过multiDrawWithAnimation函数驱动整个动画流程。 - 模态框系统构建：创建了
showModalWithConfig和closeModal方法，配合modalConfig响应式对象，实现了高度可配置的模态框。所有相关操作（showDeleteGroupModal,showAddGroupModal等）均基于此系统重构。 - URL参数深度同步：在
parseUrlParams和updateUrlParams函数中，新增了对probabilityRanges数组的编解码逻辑（encodeProbabilityRanges/decodeProbabilityRanges），实现了权重设置的URL持久化。 - 状态管理与侦听：
watch侦听器现在深度监听probabilityRanges数组，确保其变化能及时更新 URL。
