这段代码实现了一个简单的点击按钮弹出提示框的功能，整体结构清晰，没有明显错误。 以下是一些优化建议： 1. 可以考虑给按钮添加一个 `id` 属性，以便通过 JavaScript 更具可读性和可维护性地获取该元素。 2. 为函数 `showMessage` 添加更多功能或根据具体需求进行扩展。 3. 可以将样式部分提取到独立的 CSS 文件中，以提高代码的结构和可维护性。 需要注意的逻辑点： 1. 对于复杂的交互逻辑，要确保函数的功能清晰明确，避免过于复杂导致难以理解和维护。 2. 如果后续有多个按钮或元素需要添加类似的交互，考虑使用事件委托来提高性能。 3. 在实际应用中，注意用户体验，例如提示信息的友好性和合理性。 [2025-03-07 21:17:59 | AI写代码神器 | 187点数解答]
