问题描述

我需要一个正则表达式来匹配包含字母，数字，空格和一些简单标点符号的字符串(.，！'/$ ).我有 ^ [A-Za-z0-9 _] * [A-Za-z0-9 _ [A-Za-z0-9 _] * $ ，它对字母数字和空格有效，但不适用于标点符号.非常感谢您的帮助.

I need a regular expression to match strings that have letters, numbers, spaces and some simple punctuation (.,!"'/$). I have ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$ and it works well for alphanumeric and spaces but not punctuation. Help is much appreciated.

推荐答案

只需在类内(在方括号内)添加标点符号和其他字符:

Just add punctuation and other characters inside classes (inside the square brackets):

[A-Za-z0-9 _.,!"'/$]*

这匹配包含空格，_，字母数字，逗号，！，，$，...的每个字符串"添加一些特殊字符时请注意，也许您需要转义它们:更多信息在这里

This matches every string containing spaces, _, alphanumerics, commas, !, ", $, ... Pay attention while adding some special characters, maybe you need to escape them: more info here
