骨架屏实现
// 骨架屏组件
class SkeletonScreen {private container: HTMLElement;private template: string;constructor(container: HTMLElement, template: string) {this.container container;this.template template;}// 显示骨架屏show(): void {this.container.innerHTML this.template;this.container.querySelectorAll(.skeleton-item).forEach(item {item.classList.add(skeleton-animation);});}// 隐藏骨架屏hide(): void {this.container.querySelectorAll(.skeleton-item).forEach(item {item.classList.remove(skeleton-animation);});}// 创建骨架屏样式static createStyles(): void {const style document.createElement(style);style.textContent .skeleton-item {background: #f0f0f0;border-radius: 4px;}.skeleton-animation {animation: skeleton-loading 1.5s infinite;}keyframes skeleton-loading {0% {background-position: -200px 0;}100% {background-position: calc(200px 100%) 0;}};document.head.appendChild(style);}
}// 使用示例
const container document.getElementById(content)!;
const template div classskeleton-item stylewidth: 100%; height: 200px;/divdiv classskeleton-item stylewidth: 60%; height: 20px; margin-top: 20px;/divdiv classskeleton-item stylewidth: 80%; height: 20px; margin-top: 10px;/div
;const skeleton new SkeletonScreen(container, template);
SkeletonScreen.createStyles();// 显示骨架屏
skeleton.show();// 加载完成后隐藏
setTimeout(() {skeleton.hide();container.innerHTML 实际内容;
}, 2000);进度反馈
// 进度反馈管理器
class ProgressManager {private progressBar: HTMLElement;private progressText: HTMLElement;constructor() {this.createProgressElements();}// 创建进度条元素private createProgressElements(): void {this.progressBar document.createElement(div);this.progressBar.className progress-bar;this.progressText document.createElement(div);this.progressText.className progress-text;document.body.appendChild(this.progressBar);document.body.appendChild(this.progressText);const style document.createElement(style);style.textContent .progress-bar {position: fixed;top: 0;left: 0;width: 0;height: 3px;background: #4CAF50;transition: width 0.3s ease;z-index: 9999;}.progress-text {position: fixed;top: 50%;left: 50%;transform: translate(-50%, -50%);background: rgba(0, 0, 0, 0.7);color: white;padding: 10px 20px;border-radius: 4px;display: none;z-index: 9999;};document.head.appendChild(style);}// 更新进度updateProgress(progress: number, text?: string): void {this.progressBar.style.width ${progress}%;if (text) {this.progressText.textContent text;this.progressText.style.display block;}if (progress 100) {setTimeout(() {this.progressBar.style.width 0;this.progressText.style.display none;}, 500);}}// 模拟进度simulateProgress(duration: number 2000): Promisevoid {return new Promise(resolve {let progress 0;const interval setInterval(() {progress Math.random() * 10;if (progress 100) {progress 100;clearInterval(interval);this.updateProgress(progress);resolve();} else {this.updateProgress(progress);}}, duration / 20);});}
}// 使用示例
const progress new ProgressManager();// 模拟文件上传进度
async function uploadFile(file: File): Promisevoid {const total file.size;let loaded 0;const reader new FileReader();reader.onprogress (event) {if (event.lengthComputable) {const percentage (event.loaded / event.total) * 100;progress.updateProgress(percentage,上传中... ${Math.round(percentage)}%);}};reader.onload () {progress.updateProgress(100, 上传完成);};reader.readAsArrayBuffer(file);
}交互响应优化
即时反馈

}// 使用示例
const button document.querySelector(button)!;
InteractionFeedback.addRippleEffect(button);InteractionFeedback.enhanceButton(button as HTMLButtonElement,async () {await new Promise(resolve setTimeout(resolve, 1000));}
);const form document.querySelector(form)!;
InteractionFeedback.enhanceFormValidation(form);视觉反馈优化

}// 使用示例
ErrorManager.initialize();// 显示错误信息
ErrorManager.showError(操作失败请重试);// 处理API错误
try {await fetch(/api/data);
} catch (error) {ErrorManager.handleApiError(error);
}离线体验优化
Service Worker管理

}// Service Worker脚本示例
const serviceWorkerScript const CACHE_NAME app-cache-v1;const OFFLINE_PAGE /offline.html;self.addEventListener(install, (event) {event.waitUntil(caches.open(CACHE_NAME).then(cache cache.add(OFFLINE_PAGE)));});self.addEventListener(fetch, (event) {event.respondWith(fetch(event.request).catch(() {return caches.match(event.request).then(response {if (response) {return response;}return caches.match(OFFLINE_PAGE);});}));});self.addEventListener(activate, (event) {event.waitUntil(caches.keys().then(cacheNames {return Promise.all(cacheNames.filter(cacheName cacheName ! CACHE_NAME).map(cacheName caches.delete(cacheName)));}));});
;// 使用示例
// 注册Service Worker
ServiceWorkerManager.register(/sw.js);// 预缓存资源
ServiceWorkerManager.precacheResources([/,/index.html,/styles.css,/app.js,/offline.html
