Regular expression for only one url validation in javascript

Question

at present i am using following regular expression

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

it validating url like https://scores.arrowsight.com/scores/ORoom/Hospital%20A1/Hospital%20A2 but it should not validate url like http://www.google.co.in/http://www.google.co.in/ above url should not allow but it allow http://www.google.co.in/http://www.google.co.in/ Can someone help me in modifying this? Thanks in advance.

Aside from needing to be URL encoded, that URL is valid. If you put it in a browser, it would work. Do you only want to allow URL safe characters? — Brigand

Technically, that is one URL, but I understand what you mean. — Brigand

@priyankapatel: There aren't two URLs. That URL is totally valid. — Blender

Try this regex with negative lookahead:

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

its only work for google.co.in/http://www.google.co.in not for scores.arrowsight.com/scores/ORoom/Hospital%20A1/…

It can be modified a bit to disallow (?:ftp|https?) anywhere after first slash.
