In joomla php there I can use $this->baseurl to get the base path, but I wanted to get the base path in jquery.

The base path may be any of the follo

Answer 1

This is an extremely old question, but here are the approaches I personally use ...

Get Standard/Base URL

As many have already stated, this works for most situations.

var url = window.location.origin;

Get Absolute Base URL

However, this simple approach can be used to strip off any port numbers.

var url = "http://" + location.host.split(":")[0];

Edit: To address the concern, posed by Jason Rice, the following can be used to automatically insert the correct protocol type ...

var url = window.location.protocol + "//" + location.host.split(":")[0];

Set Base URL

As a bonus -- the base URL can then be redefined globally.

document.head.innerHTML = document.head.innerHTML + "";
