这是一个双层饼状图数据可视化工具的HTML框架代码，已经实现了基本的界面布局和样式设计。以下是代码的主要特点和需要完善的部分： 代码特点： 1. 使用了Chart.js库来实现数据可视化 2. 响应式设计，适配不同屏幕尺寸 3. 现代化UI设计，包含毛玻璃效果和渐变色 4. 表单控件样式统一，交互效果完善 需要完善的部分： 1. 缺少JavaScript逻辑代码来创建和更新饼状图 2. 表单提交功能未实现 3. 颜色选择器的交互逻辑需要补充 4. 数据项的添加/删除功能需要实现 建议补充的JavaScript代码框架： ```javascript document.addEventListener('DOMContentLoaded', function() { // 初始化图表 const ctx = document.getElementById('doublePieChart').getContext('2d'); let chart = new Chart(ctx, { type: 'pie', data: { labels: [], datasets: [{ label: '外层数据', data: [], backgroundColor: [], borderWidth: 1 }, { label: '内层数据', data: [], backgroundColor: [], borderWidth: 1 }] }, options: { responsive: true, plugins: { legend: { position: 'top', }, title: { display: true, text: '双层饼状图' } } } }); // 表单提交事件 document.getElementById('dataForm').addEventListener('submit', function(e) { e.preventDefault(); // 获取表单数据并更新图表 updateChart(); }); function updateChart() { // 实现图表更新逻辑 } }); ``` 三条额外需要注意的逻辑点： 1. 确保内外层数据的长度匹配，避免图表显示异常 2. 颜色数组长度需要与数据数组长度一致 3. 添加数据验证逻辑，防止无效数据导致图表错误 [2025-07-08 23:12:43 | AI写代码神器 | 419点数解答]
