<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>天天开心</title> </head> <body> <script> for (let i = 0; i < 520; i++) { document.write("雷昶斌天天开心<br>"); } </script> </body> </html>
这段代码可以实现输出 520 次“雷昶斌天天开心<br>”的效果。不过从优化和可读性的角度来看，有几点可以注意： 1. 尽量避免使用 `document.write` ，因为它可能会在页面加载完成后修改页面内容，导致一些不可预测的问题。可以考虑使用 DOM 操作来添加内容，比如创建一个元素并将其添加到页面中。 2. 可以将循环中的逻辑提取为一个函数，以提高代码的可维护性和可读性。 3. 在实际开发中，建议对代码进行必要的错误处理，以应对可能出现的异常情况。 另外需要注意的逻辑点： 1. 循环的次数要根据实际需求合理设置，避免过度消耗资源。 2. 考虑代码的可扩展性，如果后续需要修改输出的内容或格式，应确保修改起来方便。 3. 注意代码在不同浏览器中的兼容性。 [2025-03-25 22:37:52 | AI写代码神器 | 206点数解答]
