Regex Expression For Url

I am pretty new to regex expression I need to validate website url with Regex expression through java script for -- example www.google.com Http is optional in my case Please help

Solution 1:

(http|https)://([\w-]+.)+[\w-]+(/[\w- ./?%&=]*)?

from: http://www.webpronews.com/validating-a-url-with-regular-expressions-2006-10

Solution 2:

Here is a regex for you that takes into consideration if the URL contains username, if it is an IP, validates general TLDs, and some more.

^((http|https|ftp)\://)?([a-zA-Z0-9\.\-]+(\:[a-zA-Z0-9\.&%\$\-]+)*@)*((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])|localhost|([a-zA-Z0-9\-]+\.)*[a-zA-Z0-9\-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{2}))(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\?\'\\\+&%\$#\=~_\-]+))*$ 

Here is how it works: regex analyzer

This has been taken from regexlib.com, and only changed so that the scheme (http, https, etc) part is optional and replaced & with &.

Simpler version

Here is a simpler version, which works well most of the time:

^((ftp|http|https):\/\/)?(\w+:{0,1}\w*@)?((\S+.[a-z]{2,6})|([0-9\.]+))(:[0-9]+)?(\S+)?$

In case you´re interested:

Group 2: The scheme (eg. http) Group 3: Username and password (optional) Group 4: Either hostname or IP Group 5: If group 4 is hostname, this group is the hostname (eg. stackoverflow.com) Group 6: If group 4 is an IP, this is the IP address Group 7: Is the port (optional) Group 8: Is the path and query, actually the rest (eg. /hello?world=foo)
