这是一个简单的在线抽签工具网页，我来分析一下代码： HTML结构清晰，包含： 1. 和说明 2. 文本输入区域(用于输入抽签选项) 3. 抽签按钮 4. 结果显示区域 JavaScript功能： 1. 获取文本输入并按行分割为数组 2. 过滤空行 3. 实现抽签动画效果 4. 最终随机选择一个结果 CSS样式： 1. 响应式布局 2. 美观的按钮和输入框样式 3. 结果突出显示 代码优化建议： 1. 可以添加输入验证，防止用户输入过多选项导致性能问题 2. 动画持续时间可以设为变量方便调整 3. 可以添加音效增强用户体验 三条额外需要注意的逻辑点： 1. split('\n')方法在不同操作系统换行符可能不同，考虑更健壮的处理方式 2. 动画停止条件(counter > 20)是硬编码，可以改为基于时间 3. 最终结果的选择与动画最后显示的结果可能不一致，逻辑上不够严谨 [2025-03-31 14:23:49 | AI写代码神器 | 228点数解答]
