使用JavaScript将方括号内的指定字符串设置为加粗样式

核心是用正则表达式匹配所有方括号包裹的内容，替换为加粗标签：

正则匹配规则 #

匹配模式：\[([^\]]+)\]

• \[：匹配左方括号（转义是因为方括号在正则里是特殊字符）
• ([^\]]+)：捕获组，匹配所有非右括号的字符（即方括号内的内容）
• \]：匹配右方括号

代码示例 #

JavaScript #

const originalStr = "[Number] years of practice in accounting and financial administration. Showcased skills in [Area of Expertise]";
const formattedStr = originalStr.replace(/\[([^\]]+)\]/g, '<strong>$1</strong>');
// 输出结果：<strong>Number</strong> years of practice in accounting and financial administration. Showcased skills in <strong>Area of Expertise</strong>

Python #

import re

original_str = "[Number] years of practice in accounting and financial administration. Showcased skills in [Area of Expertise]"
formatted_str = re.sub(r'\[([^\]]+)\]', r'<strong>\1</strong>', original_str)
// 输出结果：<strong>Number</strong> years of practice in accounting and financial administration. Showcased skills in <strong>Area of Expertise</strong>

可选：生成Markdown加粗格式 #

如果需要Markdown原生的加粗效果（而非HTML标签），只需把替换目标改成**$1**（JS）或**\1**（Python）：

JavaScript示例 #

const formattedMarkdown = originalStr.replace(/\[([^\]]+)\]/g, '**$1**');
// 输出结果：**Number** years of practice in accounting and financial administration. Showcased skills in **Area of Expertise**

Python示例 #

formatted_markdown = re.sub(r'\[([^\]]+)\]', r'**\1**', original_str)
// 输出结果：**Number** years of practice in accounting and financial administration. Showcased skills in **Area of Expertise**
