Javascript to validate URL

Question

I have a text box where the user will enter a URL, and I need to validate this URL.

For example: I'm only trying to validate this part:

(https/http/ftp://www.gmail.two letters here)

I mentioned two letters there because many TLDs exist such as .cc, .me, etc.

I tried this regex which did not work:

(/((http|https):\/\/(\w+:{0,1}\w*@)?(\S+)|)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/)

Correct me if I'm wrong.

Answer 1

Could just simply use:

((https?|ftp):\/\/)+([\w\d\.]+([\w]{2,6})?)

Depending on what your need is, you can go with simplicity or with... overkill. :p
