Regular expression causes js hint error

Question

Hi I am using this RegExp to parse a url.

var urlRegex = /^(?:(?:ht)tp(?:s?)\:\/\/|~\/|\/)?(?:\w+:\w+@)?((?:(?:[-\w\d{1-3}]+\.)+(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|edu|co\.uk|ac\.uk|it|fr|tv|museum|asia|local|travel|[a-z]{2}))|((\b25[0-5]\b|\b[2][0-4][0-9]\b|\b[0-1]?[0-9]?[0-9]\b)(\.(\b25[0-5]\b|\b[2][0-4][0-9]\b|\b[0-1]?[0-9]?[0-9]\b)){3}))(?::[\d]{1,5})?(?:(?:(?:\/(?:[-\w~!$+|.,=]|%[a-f\d]{2})+)+|\/)+|\?|#)?(?:(?:\?(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=?(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)(?:&(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=?(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)*)*(?:#(?:[-\w~!$ |\/.,*:;=]|%[a-f\d]{2})*)?$/i;

The problem is it causes an error in js hint:

message="Unescaped '-'."

Is the a way around this?

You'd better to write how you want to parse `URL` with desire result ! — nanobash, Mar 20 '14 at 09:59
To clarify the regex is fine, that it's causing a jslint error is the problem. — user3310447, Mar 20 '14 at 10:06

Try:

var urlRegex = /^(?:(?:ht)tp(?:s?)\:\/\/|~\/|\/)?(?:\w+:\w+@)?((?:(?:[\-\w\d{1-3}]+\.)+(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|edu|co\.uk|ac\.uk|it|fr|tv|museum|asia|local|travel|[a-z]{2}))|((\b25[0-5]\b|\b[2][0-4][0-9]\b|\b[0-1]?[0-9]?[0-9]\b)(\.(\b25[0-5]\b|\b[2][0-4][0-9]\b|\b[0-1]?[0-9]?[0-9]\b)){3}))(?::[\d]{1,5})?(?:(?:(?:\/(?:[\-\w~!$+|.,=]|%[a-f\d]{2})+)+|\/)+|\?|#)?(?:(?:\?(?:[\-\w~!$+|.,*:]|%[a-f\d{2}])+=?(?:[\-\w~!$+|.,*:=]|%[a-f\d]{2})*)(?:&(?:[\-\w~!$+|.,*:]|%[a-f\d{2}])+=?(?:[\-\w~!$+|.,*:=]|%[a-f\d]{2})*)*)*(?:#(?:[\-\w~!$ |\/.,*:;=]|%[a-f\d]{2})*)?$/i;

(I've replaced all [-\w\d... with [\-\w\d...)
