智能学号抽取系统 V3.7.5 —— 一个基于 Vue.js 的交互式网页应用

在教学和课堂管理中，公平、随机地抽取学生是教师常见的需求。为了满足这一场景，我开发了一款功能强大、界面美观、操作简便的智能学号抽取系统（版本 V3.7.5），该系统使用 HTML + CSS + Vue.js 构建，支持多种抽取模式、概率权重设置以及历史记录等功能。

🌟 系统亮点

多种抽取模式：支持单次抽取与快速滚动抽取，适用于不同教学场景。
批量抽取功能：一次抽取多个学号，提升效率。
自定义概率权重：为不同的学号区间设置不同的抽取概率，实现“重点抽查”或“均匀分布”等策略。
响应式设计：适配手机和平板设备，随时随地使用。
动画与视觉反馈：丰富的按钮交互效果、庆祝动画、历史记录高亮等增强用户体验。
URL 参数保存配置：方便分享或重复使用特定设置。

🧩 技术架构

本系统采用Vue.js 3 Composition API进行状态管理与页面渲染，结合现代 CSS 技术（如 Flexbox、Grid、CSS 变量、过渡动画等），实现了良好的可维护性与扩展性。

前端资源引入如下：

Font Awesome 提供图标支持。
使用 CDN 引入 Vue.js。
所有逻辑封装在单个 HTML 文件中，便于部署和分发。

📐 功能详解

在这里插入图片描述

1. 学号范围设置

用户可以输入起始与结束学号，并选择抽取模式：

单次抽取模式（d）：点击按钮手动抽取一个学号。
快速抽取模式（s）：连续滚动显示随机学号，点击停止后记录当前结果。

2. 概率权重设置（高级功能）

通过展开“高级设置”，用户可以添加多个学号区间并为其设置不同的抽取概率权重。例如：

1~20 权重 80%
21~40 权重 20%

这样可以在不完全随机的前提下控制抽取倾向，适用于需要侧重某些学生的场景。

3. 历史记录展示

每次抽取的结果都会记录在历史区域中，最新抽取的学号会以动画形式突出显示。

4. 批量抽取

支持一次性抽取多个学号，适合小组活动、点名等场合，提高效率。

5. 庆祝动画

当所有学号都被抽取完毕时，系统会自动触发一个烟花般的彩纸动画，并弹出提示信息，增加互动趣味性。

💡 使用建议

教师课堂点名：公平、高效地随机抽取学生回答问题。
小组活动分配：批量抽取若干学生组成临时小组。
教学演示工具：用于讲解概率、统计等数学概念的实际应用案例。
游戏化教学：结合奖励机制，提升学生参与积极性。

🔧 开发说明

本项目完全开源，无需服务器即可运行，只需将代码保存为 .html 文件并在浏览器中打开即可使用。非常适合嵌入到学校管理系统、教学平台或作为独立工具使用。
