This article mainly introduces the mobile phone number how to use JS regular expression verification, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Concept

A regular expression is a logical formula for manipulating a string, that is, a "regular string" is formed by predefined specific characters and a combination of these specific characters. This "regular string" is used to express a filtering logic for a string.

Brief introduction

A regular expression is a logical formula for manipulating strings (including ordinary characters (for example, letters between an and z) and special characters (called "metacharacters"). It is to use predefined specific characters and a combination of these specific characters to form a "regular string", which is used to express a filtering logic for a string. A regular expression is a text pattern that describes one or more strings to match when searching for text.

The front-end regular expression verification is often the most numerous and the most complex, so I have sorted out some regular expressions that I have used recently, hoping to be helpful to everyone!
