这段代码整体上实现了一个简单的计时器功能,逻辑较为清晰。以下是一些可能的优化和改进建议: 1. 可以添加一些错误处理,例如在 `setInterval` 调用中,如果出现异常可以进行适当的处理。 2. 可以将 `updateDisplay` 函数中的字符串拼接部分提取为一个单独的函数,以提高代码的可读性和可维护性。 3. 在 `resetTimer` 函数中,可以添加一个条件判断,如果计时器本来就没有运行,就不需要执行一些重置操作,避免不必要的计算。 需要注意的逻辑点: 1. 确保在页面加载完成后,相关的元素(如按钮、显示区域)已经正确渲染,否则可能导致点击事件无法正常触发。 2. 对于计时器的精度要求,如果需要更高精度的计时,可以考虑使用更精确的计时方法。 3. 在代码的维护和扩展方面,建议为每个函数添加详细的注释,以便后续理解和修改。 [2025-04-28 22:10:35 | AI写代码神器 | 213点数解答]
