Question

Can you help me convert the link:

http://i.example.com/pbabp.jpg

to:

http://www.example.com/show/i/pbabp.jpg

using regex in JavaScript?

Answer 1

Pick the part before .example.com and put it after it together with /show/:

input.replace(/^(http:\/\/)(.+?)(\.example\.com)/i, "$1www$3/show/$2");

Replace http by https? if you need to match both http://... and https://....
