js match group动态词包 conststr ='[节日]abc[男女]xyz[节日]???[他她';constrel_names = ["[日期]","[星期]","[节日]","[男性女性]","[帅哥美女]","[他她]","[反性别-夫妻]","[年龄范围]","[热门手机品牌]","[地区]"]; str.match(/(\[\W+\])/g);// (3) ["[节日]",
let str = "Hello world, this is a test."; let regex = /\b\w+\b/g; // 匹配单词边界内的单词字符 let matches = str.match(regex); console.log(matches); // 应该输出: ["Hello", "world", "this", "is", "a", "test"]
在Node.js中,可以使用正则表达式中的group匹配。group匹配是指在正则表达式中使用括号()来捕获匹配的子字符串。捕获的子字符串可以通过RegExp对象中的exec()或match()方法获取。 以下是使用group匹配的示例: 代码语言:javascript 复制 // 用正则表达式中的`group`匹配constregex=/(\d{3})-(\d{2})-(\d{4}...
RegExp group constphoneNumber =`18123456789`; phoneNumber.replace(/^(\d{3})(\d{4})(\d{4})$/,function(match, group1, group2, group3) {console.log("match, group1, group2, group3 =", match, group1, group2, group3); });// match, group1, group2, group3 = 18123456789 181 ...
正则表达式(Regular Expression),在代码中常简写为 regex、regexp或RE。使用单个字符串来描述、匹配一系列符合某个句法规则的字符串搜索模式。 搜索是可用于文本搜索和文本替换。 语法: /正则表达式主体/修饰符(可选) 1. 在javascript 中, 正则表达式通常用于两个字符串方法:search()和replace()。
/* regexObj.exec(str) */ //如果匹配成功,exec() 方法返回一个数组,并更新正则表达式对象的属性。返回的数组将完全匹配成功的文本作为第一项,将正则括号里匹配成功的作为数组填充到后面。 //如果匹配失败,exec() 方法返回 null。 //紧跟在任何量词 *、 +、? 或 {} 的后面,将会使量词变为非贪婪(匹配尽...

For IE 11, you'll also need a polyfill to support unicode regex patterns. For example,const rewritePattern = require('regexpu-core'); const {generateRegexpuOptions} = require('@babel/helper-create-regexp-features-plugin/lib/util'); const {RegExp} = global; try { new RegExp('a', 'u...
