Here is the holy grail: Here is a nice example of this regular expression in action Please feel free to modify this JSBin, add examples, and update this regular expression, and I will update within this blog post.

Here is an explanation of the regular expression for those who care( ( // brackets covering match for protocol (optional) and domain ([A-Za-z]:(? ) // match protocol, allow in format or mailto: (? // allow something@ for email addresses [A-Za-z0-9\.\-] // anything looking at all like a domain, non-unicode domains | // or instead of above (? :[\-\ =&;%@\.\w]*) // allow optional query string starting with ?

and give it an expression to match against the specified control’s content.

There are even built in expressions to choose from…of which is “Internet URL”. Below is my helper method for doing this, but you can easily write the check inline if you wish.

However, using a regex to match an URL is error prone : better rely on existing frameworks doing it better (there are a lot of potential traps in url, like parameters, unkown domains, url containing ip instead of domain....) No.

While code-only answers that address the question's problem are valid (if they "address the question's problem"), they are unrecomended, and in some cases, inappropriate, as they don't address why they are correct, which is the most important part of a good answer.

Also, single weird leading and/or trailing characters aren’t tested for. Regex Rgx Url = new Regex("(([a-z A-Z][0-9a-z A-Z \-\.]*:)? Text))else The above code will validate URL's without http also. Selector .selector_input_interaction .selector_input. Selector .selector_input_interaction .selector_spinner. I’ve just come across a pretty common requirement to convert any text that looks like a link into a link within some HTML text.
