location.host vs location.hostname and cross-browser compatibility?

Solution 1:

As a little memo: the interactive link anatomy

--

In short (assuming a location of http://example.org:8888/foo/bar#bang):

• hostname gives you example.org
• host gives you example.org:8888

Solution 2:

host just includes the port number if there is one specified. If there is no port number specifically in the URL, then it returns the same as hostname. You pick whether you care to match the port number or not. See https://developer.mozilla.org/en/window.location for more info.

I would assume you want hostname to just get the site name.

Solution 3:

If you are insisting to use the window.location.origin You can put this in top of your code before reading the origin

if (!window.location.origin) {
  window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}
