[javascript] Redirecting to a relative URL in JavaScript

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?

I'm trying to redirect my current web site to other section on the same page, using JavaScript. This follow code work for me:

location.href='/otherSection'

https://developer.mozilla.org/en-US/docs/Web/API/Location/assign

• window.location.assign("../"); // one level up
• window.location.assign("/path"); // relative to domain

try following js code

location = '..'

redirect to ../

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.

<a href="..">no JS needed</a>

.. means parent directory.
