Forcing Javascript Redirection

Question

I am trying to implement what seems to be very simple JavaScript redirection, via the following rudimentary command:

window.location.href = "http://www.somesite.com";

So far so good, it works. I also can do it via the following method:

location.replace("http://www.somesite.com");

No problem here, it works again! The problem comes when I loose the protocol out of the string:

window.location.href = "www.somesite.com";

OR:

location.replace("www.somesite.com");

It just appends the new location to the current url:

www.currentsite.com/www.somesite.com

Of cause, that's not what I want. Is there any way to force the redirect?

Answer 1

One way is to use protocol-relative url like this:

window.location = "//www.somesite.com";

Or

window.location = "//somesite.com";

This way, it would redirect and browser itself will take care of figuring out protocol part eg http or https

Working Example

Answer 2

The protocol is required.

How else would the browser know whether

location.replace("mysite.pl");

was going to a Polish website or a Perl script on the current website?
