javascript jQuery正则表达式，用于验证URL

Question

I'm using following regex for validate a url,

jQuery.validator.addMethod("url_validation", function (value, element) {
return this.optional(element) || /^(([http|https|HTTPS|HTTP]+:\/\/))?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/i.test(value);
}, "error");

This regex working fine. But when I validate http://www.alfaromeo.com/com/#/home , it says the url is invalid. When I enable #, the regex fail to validate some validations. So, can anyone give a suggestion to modify this regex to validate #, which is inside a url.

I refered regular expressions how to validate a URL to get this regex.

Thanx.

^(([http|https|HTTPS|HTTP]+:\/\/))?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([#-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$

I changed

(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)

to

(\/([#-+_~.\d\w]|%[a-fA-f\d]{2,2})*)

Even so, don't expect it to work on every URL you might throw at it...
