Convert text into links with javascript [duplicate]

Question

Detect any URLs in a plain-text and convert em into links, but if its already a link, do nothing.

var text = 'text with link <a href="/">www.google.com</a>, another link www.google.com';

the result should be:

var text = 'text with link <a href="/">www.google.com</a>, another link <a href="www.google.com">www.google.com</a>';

@GopikrishnaS—not really a duplicate, that question is about just URIs in strings, but this question wants to also ignore existing HTML links in text and only convert plain text URIs. — RobG

You can parse with a regexp than looks for urls (search google for examples). Then you need get the index of the string (the located url ) inside de text and make the change (put an "a" attribute arround the link). Then get again other index, until get the EOF.

Can you show me how to do that?

This isn't an answer. If you can write a regular expression that will do this reliably and robustly in a general case (i.e. not limited by protocol, port, fragment, query, etc.), then you are able to do something that no one else has been able to do.

RobG: Maybe is not the best way, but this will work, because simply I'm looking for a string inside a string and then I can append to them every thing I want.
