}搜索功能的关键特性:
💼 搜索优化提示:实现搜索防抖功能,避免频繁API调用,提升性能和用户体验
通过本节CSS3电商商城首页设计的学习,你已经掌握:
A: 使用CSS Grid的auto-fill和minmax()函数实现自适应布局,设置合适的最小宽度(如280px),让商品卡片自动换行排列。
A: 使用lazy loading延迟加载、WebP格式图片、响应式图片(srcset)、图片压缩等技术,同时考虑使用CDN加速。
A: 前端实现搜索UI和防抖功能,后端提供搜索API支持模糊匹配、分类筛选、排序等功能,使用Elasticsearch等搜索引擎提升性能。
A: 使用CSS的::after伪元素或独立的span元素显示数量,通过JavaScript动态更新数量,添加动画效果提升用户体验。
A: 优化商品展示(高质量图片、清晰价格)、简化购买流程、添加用户评价、使用紧迫感设计(限时优惠)、优化页面加载速度等。
// 🎉 商品图片懒加载
const imageObserver = new IntersectionObserver((entries, observer) => {
entries.forEach(entry => {
if (entry.isIntersecting) {
const img = entry.target;
img.src = img.dataset.src;
img.classList.remove('lazy');
observer.unobserve(img);
}
});
});
document.querySelectorAll('img[data-src]').forEach(img => {
imageObserver.observe(img);
});// 🎉 搜索防抖实现
function debounce(func, wait) {
let timeout;
return function executedFunction(...args) {
const later = () => {
clearTimeout(timeout);
func(...args);
};
clearTimeout(timeout);
timeout = setTimeout(later, wait);
};
}
const searchInput = document.querySelector('.search-input');
const debouncedSearch = debounce(performSearch, 300);
searchInput.addEventListener('input', (e) => {
debouncedSearch(e.target.value);
