Replace subdomain name with other subdomain Using JavaScript?

Question

I'm trying to replace the subdomain name from "news.domain.com/path/.." to "mobile.domain.com/path/..", using JavaScript

Any idea how to achieve this?

I'm assuming that you want to change a string in the generic format xxxx.domain.com/... into mobile.domain.com/.... This regexp should do it in JavaScript:

var oldPath = "news.domain.com/path/";
var newPath = oldPath.replace(/^[^.]*/, 'mobile')
