Regular expression for validating url Free chat of xxx witout login
I am using Regular expression validator for validating URL (of validators) Here is the expression: http(s)? Also, next time, you might want to include the programming language or context, because regex processors vary greatly in feature support. :[-a-z0-9] \.)*[-a-z0-9] .*)/i What this matches: Anything that starts with https://, or They prevent those specific groups of characters from being assigned a number.
It works well for fully qualified URL, but doesnt work if we use URL without http or https That is it validates: but not validates com what i need is that in addition to current behaviour, it validates the url not having http specifying, that is it should validate com too Thanks Friends Manish Sadhwani if your regex processor has trouble. It's not terribly strict, but it matches all standard domain names (but might let slip through some invalid ones).
Just imagine you’re doing this before testing modifier to all the regexes to speed up the tests. Here’s a plain text list of all the URLs used in the test.
$_iu S I have added simple network ranges validation, the rules I used are: - valid range 184.108.40.206 - 220.127.116.11, network adresses above and including 18.104.22.168 are reserved addresses - first and last IP address of each class is excluded since they are used as network broadcast addresses since I don't think this is worth implementing completely in a regular expression, a following pass should exclude the Intranet address space: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 1.255 192.168.0.0 - 192.168.255.255 the loopback and the automatic configuration address space: 127.0.0.0 - 127.255.255.255 169.254.0.0 - 169.254.255.255 while the local, multicast and and the reserved address spaces: 0.0.0.0 - 0.255.255.255 (SPECIAL-IPV4-LOCAL-ID-IANA-RESERVED) 22.214.171.124 - 239.255.255 (MCAST-NET) 240.0.0.0 - 255.255.255.255 (SPECIAL-IPV4-FUTURE-USE-IANA-RESERVED) should already be excluded by the above regular expression.
Negative lookahead is used instead NOTE, that package does fuzzy search, not strict validation. If they copy it out and back into a browser so they may not know what's wrong with it upon visual inspection.

Using this method we can match both full URLs from our list, the Pen 33bd4e5c25c1873b0e836743eec21967 by Kevin Gimbel (@kevingimbel) on Code Pen.When there's a form there's a chance it contains a input field for URLs or E-Mails.
