这是一个大学生"时间银行"商业计划书的HTML页面。我来分析并提供优化建议： 1. 当前代码优点： - 使用了语义化的HTML5结构 - 响应式设计(max-width和auto margin) - 清晰的CSS样式分层 - 基本的文档下载功能实现 2. 可优化点： ```javascript // 改进后的下载函数 function exportDocument(type) { const tables = document.querySelectorAll('table'); let content = document.querySelector('h1').textContent + '\n\n'; // 处理文本内容 document.querySelectorAll('.section').forEach(section => { content += section.querySelector('h2').textContent + '\n'; section.querySelectorAll('p, h3').forEach(el => { content += el.textContent + '\n'; }); // 处理表格数据 const table = section.querySelector('table'); if (table) { const rows = table.querySelectorAll('tr'); rows.forEach(row => { const cells = row.querySelectorAll('th, td'); const rowData = Array.from(cells).map(cell => cell.textContent); content += rowData.join(type === 'csv' ? ',' : '\t') + '\n'; }); content += '\n'; } }); // 生成文件 const mimeTypes = { 'doc': 'application/msword', 'csv': 'text/csv;charset=utf-8' }; const ext = type === 'csv' ? 'csv' : 'doc'; const blob = new Blob([type === 'csv' ? '\ufeff' + content : content], { type: mimeTypes[ext] }); const url = URL.createObjectURL(blob); const a = document.createElement('a'); a.href = url; a.download = `时间银行商业计划书.${ext}`; document.body.appendChild(a); a.click(); setTimeout(() => { document.body.removeChild(a); URL.revokeObjectURL(url); }, 100); } // 更新按钮调用 document.querySelector('.download-btns').addEventListener('click', (e) => { if (e.target.tagName === 'BUTTON') { const type = e.target.textContent.includes('Word') ? 'doc' : 'csv'; exportDocument(type); } }); ``` 3. 优化建议： - 使用事件委托处理下载按钮 - 统一导出逻辑避免重复代码 - 更完整的表格数据处理 - 添加内存清理机制 4. 额外注意事项： - 导出的Word文档格式较简单，如需复杂格式建议使用docx.js库 - CSV导出应考虑特殊字符转义 - 移动端体验需要额外测试 [2025-05-24 19:26:34 | AI写代码神器 | 593点数解答]
