var w = new RegExp();
Also, can anyone recode this so that the following url would also work..
Can anyone help?

I am not sure how you have derived your regex but it is completely wrong.
e.g. [www] means match w or w or w, not www.
The “safe” characters in a URL are alphanumerics (A to Z, a to z and 0 to 9) and the following special characters: the dollar sign (“$”), hyphen (“-”), underscore (“_”), period (“.”), plus sign (“+”), exclamation point (“!”), asterisk (“*”), apostrophe (“'”), left parenthesis (“(”), and right parenthesis (“)”).
The regex you desire (i.e. validate a URL) is:-
& and ? cannot normally appear as part of a URL except in query string.
A tilde ~ is not "safe" character but I have included it. A space should be encoded as %20
What is w.compile supposed to do?
In fact it may be simpler and just as effective to just check the starting characters in the URL up to www.
