二、AI设计工具实战

2.1 AI生成设计灵感

假设我们要设计一个电商首页，让AI帮我们生成设计灵感：

// ai-design-mockup.js class AIDesignGenerator { static generateColorPalette(baseColor) { const palettes = { warm: ['#FF6B35', '#F7C59F', '#EFEFD0', '#004E89', '#1A659E'], cool: ['#4ECDC4', '#45B7D1', '#96CEB4', '#FFEAA7', '#DDA0DD'], neutral: ['#2C3E50', '#34495E', '#7F8C8D', '#BDC3C7', '#ECF0F1'], vibrant: ['#E74C3C', '#3498DB', '#2ECC71', '#F39C12', '#9B59B6'] }; if (baseColor) { return this.generateCustomPalette(baseColor); } const keys = Object.keys(palettes); return palettes[keys[Math.floor(Math.random() * keys.length)]]; } static generateCustomPalette(baseColor) { const hex = baseColor.replace('#', ''); const r = parseInt(hex.substr(0, 2), 16); const g = parseInt(hex.substr(2, 2), 16); const b = parseInt(hex.substr(4, 2), 16); return [ baseColor, this.shadeColor(baseColor, 20), this.shadeColor(baseColor, -20), this.complementColor(r, g, b), this.analogousColor(r, g, b) ]; } static shadeColor(color, percent) { const num = parseInt(color.replace('#', ''), 16); const amt = Math.round(2.55 * percent); const R = Math.min(255, Math.max(0, (num >> 16) + amt)); const G = Math.min(255, Math.max(0, ((num >> 8) & 0x00FF) + amt)); const B = Math.min(255, Math.max(0, (num & 0x0000FF) + amt)); return `#${(0x1000000 + R * 0x10000 + G * 0x100 + B).toString(16).slice(1)}`; } static complementColor(r, g, b) { return `#${((0xFFFFFF ^ (r << 16 | g << 8 | b)) >>> 0).toString(16).padStart(6, '0')}`; } static analogousColor(r, g, b) { const hsl = this.rgbToHsl(r, g, b); const h1 = (hsl.h + 30) % 360; return this.hslToRgb(h1, hsl.s, hsl.l); } static rgbToHsl(r, g, b) { r /= 255; g /= 255; b /= 255; const max = Math.max(r, g, b); const min = Math.min(r, g, b); let h, s, l = (max + min) / 2; if (max === min) { h = s = 0; } else { const d = max - min; s = l > 0.5 ? d / (2 - max - min) : d / (max + min); switch (max) { case r: h = ((g - b) / d + (g < b ? 6 : 0)) / 6; break; case g: h = ((b - r) / d + 2) / 6; break; case b: h = ((r - g) / d + 4) / 6; break; default: h = 0; } } return { h: h * 360, s, l }; } static hslToRgb(h, s, l) { h /= 360; const a = s * Math.min(l, 1 - l); const f = n => { const k = (n + h * 6) % 6; return Math.round(255 * (l - a * Math.max(Math.min(k, 4 - k, 1), 0))); }; return `#${(0x1000000 + f(5) * 0x10000 + f(3) * 0x100 + f(1)).toString(16).slice(1)}`; } static generateTypography() { const fontFamilies = [ 'Inter, system-ui, sans-serif', 'Roboto, sans-serif', 'Poppins, sans-serif', 'Montserrat, sans-serif', 'Open Sans, sans-serif' ]; return { primary: fontFamilies[Math.floor(Math.random() * fontFamilies.length)], sizes: { heading1: '3rem', heading2: '2.5rem', heading3: '2rem', body: '1rem', caption: '0.875rem' }, weights: { light: 300, regular: 400, medium: 500, bold: 700 } }; } static generateLayout() { const layouts = [ { name: 'single-column', maxWidth: '600px', columns: 1 }, { name: 'two-column', maxWidth: '1200px', columns: 2 }, { name: 'three-column', maxWidth: '1400px', columns: 3 }, { name: 'grid', maxWidth: '1600px', columns: 4 } ]; return layouts[Math.floor(Math.random() * layouts.length)]; } } export { AIDesignGenerator };

2.2 使用AI生成设计系统

// design-system-generator.js import { AIDesignGenerator } from './ai-design-mockup'; class DesignSystemGenerator { static generate() { const palette = AIDesignGenerator.generateColorPalette('#6366F1'); const typography = AIDesignGenerator.generateTypography(); const layout = AIDesignGenerator.generateLayout(); return { name: 'AI Generated Design System', palette: { primary: palette[0], primaryDark: palette[1], primaryLight: palette[2], accent: palette[3], secondary: palette[4], background: '#FFFFFF', surface: '#F8FAFC', text: '#1E293B', textSecondary: '#64748B', border: '#E2E8F0' }, typography, layout, spacing: { xs: '0.25rem', sm: '0.5rem', md: '1rem', lg: '1.5rem', xl: '2rem', '2xl': '3rem' }, borderRadius: { sm: '0.25rem', md: '0.5rem', lg: '0.75rem', xl: '1rem', full: '9999px' }, shadows: { sm: '0 1px 2px 0 rgba(0, 0, 0, 0.05)', md: '0 4px 6px -1px rgba(0, 0, 0, 0.1), 0 2px 4px -1px rgba(0, 0, 0, 0.06)', lg: '0 10px 15px -3px rgba(0, 0, 0, 0.1), 0 4px 6px -2px rgba(0, 0, 0, 0.05)', xl: '0 20px 25px -5px rgba(0, 0, 0, 0.1), 0 10px 10px -5px rgba(0, 0, 0, 0.04)' } }; } } export { DesignSystemGenerator };

三、AI生成UI组件

3.1 AI生成按钮组件

// ai-component-generator.js class AIComponentGenerator { static generateButton(designSystem, variant = 'primary') { const variants = { primary: { backgroundColor: designSystem.palette.primary, color: '#FFFFFF', hoverBackgroundColor: designSystem.palette.primaryDark, border: 'none' }, secondary: { backgroundColor: 'transparent', color: designSystem.palette.primary, hoverBackgroundColor: designSystem.palette.surface, border: `1px solid ${designSystem.palette.primary}` }, outline: { backgroundColor: 'transparent', color: designSystem.palette.text, hoverBackgroundColor: designSystem.palette.surface, border: `1px solid ${designSystem.palette.border}` }, ghost: { backgroundColor: 'transparent', color: designSystem.palette.textSecondary, hoverBackgroundColor: designSystem.palette.surface, border: 'none' } }; const styles = variants[variant] || variants.primary; return { type: 'button', variant, styles: { base: { display: 'inline-flex', alignItems: 'center', justifyContent: 'center', padding: `${designSystem.spacing.sm} ${designSystem.spacing.md}`, borderRadius: designSystem.borderRadius.md, fontSize: designSystem.typography.sizes.body, fontWeight: designSystem.typography.weights.medium, fontFamily: designSystem.typography.primary, cursor: 'pointer', transition: 'all 0.2s ease', backgroundColor: styles.backgroundColor, color: styles.color, border: styles.border }, hover: { backgroundColor: styles.hoverBackgroundColor }, disabled: { opacity: '0.5', cursor: 'not-allowed' }, sizes: { sm: { padding: `${designSystem.spacing.xs} ${designSystem.spacing.sm}`, fontSize: designSystem.typography.sizes.caption }, md: { padding: `${designSystem.spacing.sm} ${designSystem.spacing.md}`, fontSize: designSystem.typography.sizes.body }, lg: { padding: `${designSystem.spacing.md} ${designSystem.spacing.lg}`, fontSize: designSystem.typography.sizes.heading3 } } } }; } static generateCard(designSystem) { return { type: 'card', styles: { base: { backgroundColor: designSystem.palette.background, borderRadius: designSystem.borderRadius.lg, boxShadow: designSystem.shadows.md, padding: designSystem.spacing.lg }, hover: { boxShadow: designSystem.shadows.lg, transform: 'translateY(-2px)' }, header: { paddingBottom: designSystem.spacing.md, borderBottom: `1px solid ${designSystem.palette.border}` }, body: { paddingTop: designSystem.spacing.md }, footer: { paddingTop: designSystem.spacing.md, borderTop: `1px solid ${designSystem.palette.border}`, display: 'flex', justifyContent: 'flex-end', gap: designSystem.spacing.sm } } }; } static generateInput(designSystem) { return { type: 'input', styles: { base: { width: '100%', padding: `${designSystem.spacing.sm} ${designSystem.spacing.md}`, borderRadius: designSystem.borderRadius.md, border: `1px solid ${designSystem.palette.border}`, fontSize: designSystem.typography.sizes.body, fontFamily: designSystem.typography.primary, backgroundColor: designSystem.palette.background, color: designSystem.palette.text, transition: 'all 0.2s ease', outline: 'none' }, focus: { borderColor: designSystem.palette.primary, boxShadow: `0 0 0 3px ${designSystem.palette.primary}20` }, error: { borderColor: '#EF4444' }, placeholder: { color: designSystem.palette.textSecondary } } }; } } export { AIComponentGenerator };

3.2 AI生成页面布局

// page-layout-generator.js class PageLayoutGenerator { static generateHomepage(designSystem) { return { type: 'homepage', sections: [ { name: 'hero', components: [ { type: 'heading', text: '欢迎来到AI设计世界', level: 1 }, { type: 'paragraph', text: '利用AI技术，让设计变得更简单、更高效' }, { type: 'button-group', buttons: [ { variant: 'primary', text: '立即开始' }, { variant: 'secondary', text: '了解更多' } ]} ], styles: { minHeight: '80vh', display: 'flex', flexDirection: 'column', alignItems: 'center', justifyContent: 'center', padding: designSystem.spacing['2xl'] } }, { name: 'features', components: [ { type: 'heading', text: '核心功能', level: 2 }, { type: 'card-grid', cards: [ { title: '智能设计', description: 'AI自动生成设计方案' }, { title: '快速原型', description: '一键生成可交互原型' }, { title: '代码导出', description: '自动生成前端代码' } ]} ], styles: { padding: designSystem.spacing['2xl'], backgroundColor: designSystem.palette.surface } }, { name: 'pricing', components: [ { type: 'heading', text: '定价方案', level: 2 }, { type: 'pricing-cards', plans: [ { name: '免费版', price: '0', features: ['基础功能', '3个项目', '社区支持'] }, { name: '专业版', price: '99', features: ['全部功能', '无限项目', '优先支持'], popular: true }, { name: '企业版', price: '299', features: ['定制开发', '专属客服', '私有化部署'] } ]} ], styles: { padding: designSystem.spacing['2xl'] } }, { name: 'cta', components: [ { type: 'heading', text: '准备好开始了吗？', level: 2 }, { type: 'button', variant: 'primary', text: '免费试用' } ], styles: { padding: designSystem.spacing['2xl'], backgroundColor: designSystem.palette.primary, textAlign: 'center', color: '#FFFFFF' } } ] }; } } export { PageLayoutGenerator };
