Redirecting to a relative URL in JavaScript

Question

I have a problem: I want to redirect via JavaScript to a directory above. My code:

location.href = (location.href).substr(0, (location.href).lastIndexOf('folder')); 

The URL looks like this:

example.com/path/folder/index.php?file=abc&test=123&lol=cool

The redirect affect just this:

example.com/path/&test=123&lol=cool

But want to have this:

example.com/path/

How could I do that?

Answer 1

You can do a relative redirect:

window.location.href = '../'; //one level up 

or

window.location.href = '/path'; //relative to domain 

Answer 2

If you use location.hostname you will get your domain.com part. Then location.pathname will give you /path/folder. I would split location.pathname by / and reassemble the URL. But unless you need the querystring, you can just redirect to .. to go a directory above.
