正则替换如何引用捕获组？How do replacement capture groups work?
使用 $1、$2 或 $<name> 引用捕获组，$& 引用完整匹配，$$ 输出美元符号。使用 JavaScript 正则语法，查找内容无需两侧斜杠。字面量模式不解释替换符号；正则计算超过一秒自动停止。Use $1, $2 or $<name> for captures, $& for the full match and $$ for a dollar sign. Enter JavaScript regex without enclosing slashes. Literal mode does not interpret replacement tokens. Regex processing stops after one second.
