Undefined pathname in js

Question

I am trying to extract the base of the url:

http://google.com/something --> http://google.com
http://127.0.0.1:8000/something --> http://127.0.0.1:8000

When I try and use the following:

var pathArray = window.location.pathname;
alert(pathArray);

I get pathArray = undefined. Note: using location.hostname does work here. Why is .pathname returning undefined, and how would I get the url base here? Thank you.

Update: I used var pathArray = 'http://' + window.location.

Path name does not return the domain name. It returns the pat after the domain name. If you're at http://example.com/a/b.html, window.location.pathname returns /a/b.html. Why not use window.location? — Alex

https://developer.mozilla.org/en-US/docs/Web/API/Window/location May not work in all browsers, as per usual

I'd just get window.location and parse it.

Try window.location.host, it works for http://localhost:8000, so it should work for your case

window.location.host won't return the port number, nor the protocol.

It does. Testing it in Firefox with Firebug

On Chrome and Firefox on localhost/index.html, using console.log(window.location.host); I get localhost returned.

Yes, because it doesnt have port number. Even the solution which you suggested doesnt work for localhost/index.html example. i.e(window.location.protocol + '//' + window.location.host;). If you want port number for mapped URL in host entries, then you have to explicitly give window.location.port
