用于在“-"之后选择值的正则表达式 [英] Regex for picking a Value After "-"

问题描述

我需要一个正则表达式，它实际上可以获取在-"破折号之后插入的任何字母，例如我有一个字符串

Hi I need a Regex that can actually get any letter that is inserted after "-" dash e.g i have a string that says

 "UpTown-R" , "Category-C"

我得到的回报是 "R" , "C".

What I get in return is "R" , "C".

推荐答案

如果总是字符串的最后一部分，你可以这样做

If is always the last part of the string, you can do this

/[^-]+$/

在 Regexr 上查看 此处

see it here on Regexr

[^-] 是匹配所有非破折号的字符类

[^-] is a character class that matches everything that is not a dash

+ 量词表示一个或多个前面的元素

+ quantifier means one or more of the preceding element

$ 字符串结尾的锚
