JavaScript 正则表达式 /v 标志(Unicode 集)


示例

let text = "Hello 😄";

let pattern = /\p{RGI_Emoji}/v;
let result = pattern.test(text);
亲自试一试 »
let text = "Hello 😄";

let pattern = /\p{RGI_Emoji}/;
let result = pattern.test(text);
亲自试一试 »

描述

/v(UnicodeSets)标志是对 /u 标志的"升级"。

它启用了更多与 Unicode 相关的功能。

新增功能包括:

  • \p 转义序列匹配的是字符串,而不仅仅是字符。
  • 字符类已升级,支持交集、并集和减法语法,以及匹配多个 Unicode 字符。

注意

同时使用/u/v标志会导致语法错误。


语法

new RegExp("regexp", "v")

或者:

/regexp/v

另请参阅:

对应的属性:unicodeSets


正则表达式方法

正则表达式的搜索替换可以使用不同的方法。

以下是最常用的方法:

字符串方法

方法 描述
match(regex) 返回结果数组
matchAll(regex) 返回结果迭代器
replace(regex) 返回一个新的字符串
replaceAll(regex) 返回一个新的字符串
search(regex) 返回第一个匹配项的索引
split(regex) 返回一个结果数组

正则表达式方法

方法 描述
regex.exec() 返回结果迭代器
regex.test() 返回 true 或 false

浏览器支持

/regexp/v 是 JavaScript 2025 的一项特性。

ES 2025 自 2025 年 5 月起,所有现代浏览器均已完全支持 ES 2025。
