looking for regex to match some part of URL

Question

I am looking for a regex to match some part of URL to redirect my pages accordingly.

I have googled it with no luck.

EX:

http://www.somesite.com/cat1/cat2/

In this i am looking to match any word or char after the domain name, so it would be /cat1/cat2/

http://www.somesite.com/cat1/cat2/cat3/

In this i am looking to match any word or char after the domain name, so it would be /cat1/cat2/cat3/

looking for 2 diff regex to match this kind of url. First regex that matches only 2 category and second regex that matches only 3 category.

Thanks guys in advance.

Answer 1

As far as I know, regexs do not support inverse matching. That means, you cannot write a regex that matches what is NOT in the regex (if I'm wrong, please someone correct me on this). That being said, you could use this:

^http:\/\/[^\/]+\/(.*)

Using grouping, you can match whatever comes after your URL domain. So, in this case, what you are looking for would be fetcheable through $1 (the group represented by the brackets at the end of the regex). Another important thing is the ^ in the beginning of the regex. This way you won't catch URL strings passed as query parameters of your URL.

Answer 2

This will work for the first case, with the desired part in the first capturing group:

^http://[^/]+(/(?:[^/]*/){2})$

Change the {2} part to {3} for the second case.

Answer 3

Sounds pretty simple.

First regex would be like : http://.+/([^/]+)/([^/]+)/

I'll let you guess what the second regex is.

Answer 4

you can get path name from windwo.location.pathname

var path = window.location.pathname

after getting this path you can get path using split('/');
