Get subdomain and load it to url with greasemonkey

Question

I am having the URL http://somesubdomain.domain.com (subdomains may vary, domain is always the same). Need to take subdomain and reload the page with something like domain.

Answer 1

var full = window.location.host
//window.location.host is subdomain.domain.com
var parts = full.split('.')
var sub = parts[0]
var domain = parts[1]
var type = parts[2]
//sub is 'subdomain', 'domain', type is 'com'
var newUrl = 'http://' + domain + '.' + type + '/your/other/path/' + subDomain
window.open(newUrl);
