使用一个正则表达式测试多个单词

Question

我有一个正则表达式，我想向它传递多个单词，然后返回与该表达式匹配的字符串。我该怎么做（使用 vanilla JS，没有 jQuery 等）？let regEx = /\^[a-zA-Z0-9]+\-[a-zA-Z0-9]+\|[a-zA-Z0-9]+/let str1 = "5"let str2 = "df-df-01"let solutions = [str1,str2].HOW(regEx) //I'd like this to return ["df-df-01"]

Answer 1

您正在寻找filter+ test：

let regEx = /^[a-zA-Z0-9]+-[a-zA-Z0-9]+-[a-zA-Z0-9]+/

let str1 = "5"

let str2 = "df-df-01"

let solutions = [str1,str2].filter(x => regEx.test(x)) 

// or .filter(/./.test.bind(regEx)) to make your teammates hate you

console.log(solutions)

还要注意固定的正则表达式。
