This article focuses on "JS regular expression Integration". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "JS regular expression Integration".

Regular expression of url: including IP, domain name (domain), ftp, second-level domain name, files in domain name, domain name plus port! User name and other information

Function IsURL (str_url) {var strRegex = "^ ((https | http | ftp | rtsp | mms)?: / /)" + "? ([0-9aMuzhuizhuangyue'(). & = + $% -] +:)? [0-9aHUZHUZHUZHUANGZHUANZHUANGZHUANG" (). & = + $% -] + @)?
