js代码实现将一段文本中的"【"替换为"<span style='color:red;'>","】"替换为"</span>"
```javascript // 定义原始文本 let originalText = "这是一段包含【特殊内容】的文本"; // 使用replace方法进行替换,第一个参数为要替换的字符,第二个参数为替换后的内容 // 由于【和】是普通字符,直接使用即可,不需要特殊处理 let replacedText = originalText.replace(/【/g, "<span style='color:red;'>").replace(/】/g, "</span>"); // 输出替换后的文本 console.log(replacedText); ``` 我在以往的开发过程中,碰到过以下几点需要格外小心处理的地方: 1. 正则表达式中的修饰符`g`不能遗漏,否则只会替换第一个匹配到的字符。 2. 当文本中包含大量需要替换的字符时,频繁使用`replace`方法可能会影响性能,可以考虑使用更高效的方法。 3. 要注意替换后的HTML代码是否会与原有的HTML结构产生冲突,避免出现显示异常的情况。 [2026-01-06 19:19:11 | AI写代码神器 | 219点数解答]
