首先你可以了解JS Regex 此处 [ ^ ]



关于正则表达式中使用的模式 - 事实证明，至少对于北美来说，有一些规范，称为 NANP 。



您需要准确指定您想要的内容 。

什么是合法分隔符？空格，破折号和句号？不允许分隔符？可以混合分隔符（例如，+ 0.111-222.3333）吗？如何处理扩展（例如，111-222-3333 x 44444）？特殊号码怎么样，比如911？区号是可选的还是必需的？



这是一个7位或10位数的正则表达式，允许扩展，分隔符是空格，破折号，或期间：



^（？:( ?: \ +？？1 \ * *（？：[.-] \ S *））（？：\（\s *（[2-9] 1 [02-9] |？[2-9] [2月8日] 1 | [2-9] [2月8日] [02-9]）\s * \）|（[2-9] 1 [02-9] | [2-9] [2月8日] 1 | [2-9] [2月8日] [02-9]））\s *（：？？？[.-] \s *））（[2-9] 1 [02-9] | [2-9] [02-9] 1 | [2-9] [02-9] {2}）\s *（：[.-] \s *）（[0-9] {4}）（?: \s *（？ ？：＃| x\。？| ext \。？|扩展名）\ * *（\ d +））？

First you can learn about JS Regex here[^]

About the pattern to use in the Regex - It turns out that there''s something of a spec for this, at least for North America, called the NANP.

You need to specify exactly what you want.
What are legal delimiters? Spaces, dashes, and periods? No delimiter allowed? Can one mix delimiters (e.g., +0.111-222.3333)? How are extensions (e.g., 111-222-3333 x 44444) going to be handled? What about special numbers, like 911? Is the area code going to be optional or required?

Here''s a regex for a 7 or 10 digit number, with extensions allowed, delimiters are spaces, dashes, or periods:

^(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:\(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*\)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+))?
