How to get domain name only using javascript?

Question

I want to get domain name only using javascript. Ex

vn.search.yahoo.com -> yahoo
vn.search.yahoo.com.vn -> yahoo
sub1.sub2.sub3.abcdef.co.uk -> abcd         


        

Answer 1

Without having a complete list of TLD's (which would get very long). If you just need the domain name from the current page you can use my technique (using cookies to find the root domain)

Javascript - Get Domain Name Excluding Subdomain

To remove the extension you can then use the first element from a str.split('.')[0]
