这段代码整体结构清晰，功能实现较为完整。以下是一些可能的优化建议： 在 `startRain` 函数中，创建元素和设置样式的部分可以提取为一个单独的函数，以提高代码的可读性和可维护性。 ```javascript function createHeart() { const heart = document.createElement("div"); heart.className = "heart-rain"; heart.innerHTML = "❤️"; heart.style.left = Math.random() * 100 + "vw"; heart.style.animationDelay = Math.random() * 2 + "s"; return heart; } function startRain() { for (let i = 0; i < 50; i++) { document.body.appendChild(createHeart()); } // 3 秒后跳转全屏爱心 setTimeout(() => { document.body.innerHTML = ` <div style="background:#ff6b6b;height:100vh;display:flex;justify-content:center;align-items:center;"> <div style="font-size:100px;animation: pulse 1s infinite">❤️</div> </div> `; }, 3000); } ``` 在处理 `setTimeout` 中的页面跳转时，可以考虑使用更灵活的 DOM 操作来替换直接修改 `innerHTML`，以避免丢失原页面中的其他可能的事件绑定和状态。 还有，对于大量创建元素的操作，需要注意性能开销，避免在短时间内创建过多元素导致页面卡顿。 [2025-02-21 01:07:39 | AI写代码神器 | 346点数解答]
