推荐答案
也许是这样的:
/(\+\d+)?\s*(\(\d+\))?([\s-]?\d+)+/
-
(\+\d+)?=一个"+"，后跟一个或多个数字(可选) -
\s*=任意数量的空格字符(可选) -
(\(\d+\))?=一个("，后跟一个或多个数字，后跟)"(可选) -
([\s-]?\d+)+=一组或多组数字，可以选择在前面加上空格或破折号 (\+\d+)?= A "+" followed by one or more digits (optional)\s*= Any number of space characters (optional)(\(\d+\))?= A "(" followed by one or more digits followed by ")" (optional)([\s-]?\d+)+= One or more set of digits, optionally preceded by a space or dash
不过，老实说，我怀疑您会发现一种表达所有规则的表达方式.电话号码可以采用多种不同的格式，以至于无法匹配任何可能的格式而没有错误的肯定或否定.
To be honest, though, I doubt that you'll find a one-expression-to-rule-them-all. Telephone numbers can be in so many different formats that it's probably impractical to match any possible format with no false positives or negatives.
