Get The Current Domain Name With Javascript (Not the path, etc.)

Question

I plan on buying two domain names for the same site. Depending on which domain is used I plan on providing slightly different data on the page. Is there a way for me to de

Answer 1

I figure it ought to be as simple as this:

url.split("/")[2]

Answer 2

Combining a few answers from the above, the following works really well for me for destroying Cookies:

  /**
   * Utility method to obtain the domain URI:
   */
  fetchDomainURI() {
    if (window.location.port.length > 0) {
      return window.location.hostname;
    }
    return `.${window.location.hostname.match(/\w*\.\w*$/gi)[0]}`;
  }

Works for IP addresses with ports, e.g., 0.0.0.0:8000 etc, as well as complex domains like app.staging.example.com returning .example.com => allows for cross-domain Cookie setting and destroying.

Answer 3

If you wish a full domain origin, you can use this:

document.location.origin

And if you wish to get only the domain, use can you just this:

document.location.hostname

But you have other options, take a look at the properties in:

document.location

Answer 4

What about this function?

window.location.hostname.match(/\w*\.\w*$/gi)[0]

This will match only the domain name regardless if its a subdomain or a main domain

Answer 5

Since this question asks for domain name, not host name, a correct answer should be

window.location.hostname.split('.').slice(-2).join('.')

This works for host names like www.example.com too.

Answer 6

       Feel free to visit our “<a href="javascript:document.location.href=document.location.origin+'/contact-us'" title="Click to Contact Us" class="coded_link" ><span class="ui-icon ui-icon-newwin"></span>Contact</a>” link

Indeed worked for me whereas I couldn't use PHP

Just tested that it worked thanks to the approach mentioned above in some of the answers, so quick and verified that worked
