How to validate a url address in jquery using Regex? [duplicate]

Question

I have searched a lot but didn't get the answer. How to validate URLs like www.google.com and http://www.google.com using regular expressions? Thanks in advance.

What do you mean by validate an URL? Check if it starts with "http://", or "www": ^(?:http|www). Have you tried anything? — Wiktor Stribiżew

You can use a function to test valid url as:

function validateUrl()   // return true or false.
{
    var urlregex = new RegExp(
          "^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}([0-9A-Za-z]+\.)");
    return urlregex.test(textval);
}

You can also use this one, that does not depend on the string start/end:

(\b((?:https?|ftp):\/\/|www\.)([0-9A-Za-z]+\.?)+\b)

See example here.
