山东继续教育学习辅助脚本：技术实现与功能解析

前言

在线学习平台已经成为继续教育的重要方式，但重复的操作流程往往会影响学习效率。本文将介绍一个基于 Tampermonkey 的浏览器脚本，它能够自动处理学习过程中的重复操作，实现视频连续播放和学习节点自动切换。

脚本概述

这是一个针对山东继续教育平台（yxlearning.com）开发的用户脚本，主要功能包括：

  • 自动播放视频内容
  • 智能跳过提示和弹窗
  • 自动切换未完成章节
  • 可视化控制面板
  • 快捷键操作支持

技术架构

1. 样式注入

脚本使用 GM_addStyle 注入自定义样式，创建了一个简洁的控制按钮：

.shi_study_btn {
    position: fixed;
    top: 0;
    left: 0;
    z-index: 999999;
    /* 其他样式... */
}

控制按钮采用固定定位，确保在页面滚动时始终可见。通过不同的类名（running/paused）实现运行状态的视觉反馈。

2. 核心学习逻辑

learn() 函数是整个脚本的核心，采用了多层兜底策略：

第一层：处理平台特定元素

  • 自动点击"跳过"按钮
  • 移除答题容器和弹窗
  • 触发播放器的播放按钮

第二层：通用视频处理

  • 遍历页面中的所有 <video> 标签
  • 静音并自动播放处于暂停状态的视频
  • 支持多种播放器实现方式

第三层：学习进度管理

  • 智能识别学习进度（通过 .badge 元素）
  • 自动跳转到未完成章节
  • 完成后自动进入下一节点

3. 状态管理

脚本实现了简单而有效的状态管理机制：

let isRunning = true;
let timer = null;
  • isRunning：控制脚本运行状态
  • timer：定时器引用，用于周期性执行学习逻辑

每 3 秒执行一次检查，确保及时响应页面变化。

4. 用户交互

可视化控制面板

创建了一个可点击的控制按钮，实时显示运行状态：

  • 运行中：绿色文字
  • 已暂停：红色文字

快捷键支持

实现了 Ctrl + Shift + S 快捷键，方便快速切换运行状态。

5. SPA 路由监听

针对单页应用（SPA）的特点，使用 MutationObserver 监听 DOM 变化：

new MutationObserver(() => {
    if (location.href !== lastUrl) {
        lastUrl = location.href;
        setTimeout(learn, 500);
    }
}).observe(document, { childList: true, subtree: true });

当检测到 URL 变化时，自动执行学习逻辑，确保页面跳转后脚本继续工作。

功能特点

1. 智能跳过机制

脚本能够识别并处理多种类型的干扰元素：

  • 课程中的"跳过"按钮
  • 过程性答题窗口
  • 各种弹窗提示

2. 多重播放保障

采用了多种方式确保视频正常播放：

  • 平台特定的播放按钮
  • 标准 HTML5 video 元素
  • 通用播放按钮选择器
  • 视频重播处理

3. 进度自动推进

通过分析页面中的进度标识（百分比），自动定位并切换到未完成的学习内容。

4. 容错处理

在视频播放时使用了 .catch() 捕获异常，避免因个别视频加载失败导致整个脚本停止运行。

    • 保存并启用

  3. 操作方式

    • 脚本会自动运行
    • 点击左上角控制按钮可暂停/恢复
    • 使用 Ctrl + Shift + S 快捷键切换状态

技术亮点

  1. 优雅的兜底策略：通过多层选择器和逻辑判断，确保在不同页面状态下都能正常工作
  2. 低侵入性：仅在必要时操作 DOM，不影响页面正常功能
  3. 良好的用户体验：提供可视化反馈和便捷的控制方式
  4. 高可维护性：代码结构清晰，注释详细，易于理解和修改

注意事项

  • 本脚本仅用于辅助学习，提高操作效率
  • 建议在使用时关注学习内容，确保学习质量
  • 不同平台版本可能需要适当调整选择器

总结

这个学习辅助脚本展示了如何使用浏览器用户脚本技术提升在线学习体验。通过自动化处理重复操作，让学习者可以更专注于内容本身。代码采用了多重保障机制，确保在各种情况下都能稳定运行。

对于开发者来说，这个项目也提供了一个很好的示例，展示了如何构建一个实用的浏览器脚本，包括 DOM 操作、事件监听、状态管理和用户交互等多个方面的技术实践。
