javascript fetch last url without prefix

Question

I am looking to detect last url from text using javascript or mootools. Url canbe without prefix/scheme

I am working on URL auto sense like Facebook. Where a user may give an URL www.example.com or with http://www.example.com either of them should be detected by JavaScript. see stackoverflow detected URL that included with scheme without URL scheme it couldn't detect URL. In my case I need both.

Here is some text

'http://www.example.com www.example2.com'

Now I want www.example2.com It will be better if I get full array containing both http://www.example.com and www.example2.com

I searched a lot but couldn't find solution. Most close to my requirements were Question about URL Validation with Regex and How do I extract a URL from plain text using jQuery?

Any help greatly appreciated.

REGEX

/([^:\/?# ]+:)?(\/\/[^\/?# ]*)?[^?# ]+(\?[^# ]*)?(#\S*)?/gi

**SAMPLE CODE**

var str = 'http://www.example.com www.example2.com scheme://username:password@domain:port/path?query_string#fragment_id';
var t = str.match(/([^:\/?# ]+:)?(\/\/[^\/?# ]*)?[^?# ]+(\?[^# ]*)?(#\S*)?/gi);

/* 
   t contains : 
   [ 
     "http://www.example.com",
     "www.example2.com",
     "scheme://username:password@domain:port/path?query_string#fragment_id"
   ]
*/

**DEMO** >http://jsfiddle.net/wvYTd/
**DISCUSSION**

This regex will find any substring that looks like an URL in an input string.
No validation is performed on any URL found. For instance, if the input string is 3aBadScheme://hostname, the regex will detect it as an URL. In this example, 3aBadScheme is invalid since a scheme MUST start with a letter.

Excerpt from RFC3986

(...)
Scheme names consist of a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus ("+"), period ("."), or hyphen ("-").

I agree with @MichalKlouda. This is just a sample text please keep in mind. I have given references also which were very close to my necessity. thanks. – ARIF MAHMUD RANA Oct 10 '12 at 08:21
I have updated the regex and the jsfiddle link. Again, if you have more url samples valid in your context, send them. – Stephan Oct 10 '12 at 08:57
@Stephan thanks. Let me explain me a bit more. I am working on URL auto sense like Facebook. Where a user may give an URL as I said www.example.com or with http://www.example.com either of them should be detected by JavaScript. – ARIF MAHMUD RANA Oct 10 '12 at 11:06
@ARIFMAHMUDRANA Check my new answer. It may now fit your needs. – Stephan Oct 10 '12 at 15:06

Given your input string, I think you just want to split it using spaces as separator? .split(' ') ?

by combing info in these 2 links: How do I extract a URL from plain text using jQuery? Detect URLs in text with JavaScript

We can get this: http://jsfiddle.net/qQwGA/1/

If I understand what you're trying to do, this should cover it.
