Is there any method to get the URL without query string?

I have a URL like http://localhost/dms/mduserSecurity/UIL/index.php?menu=true&submenu=true&pcode=1235.

I want to get the URL without the query string: http://localhost/dms/mduserSecurity/UIL/index.php.

Is there any method for this in JavaScript? Currently I am using document.location.href, but it returns the complete URL.
