jQuery: Redirect user if urls equals not

Question

I want to redirect user to a specific page, when they are not on this page.

So something like (pseudo code):

if not (url = example.com/index.php)
   redirect to example.com/index.php
/if

When a user e.g. visit page example.com/forum.php he will be redirected to example.com/index.php

(The jQuery file is loaded in every file)

How can I archive that?

You can use window.location.href. Example here...

if(url === 'example.com/forum.php'){
    window.location.href = 'example.com/index.php';
    return False;
}

Don't forget to use return false at the end of the block so that if there are any runnable code after the window.location.href, then browser can ignore that

Yes that works, but I figured out, that the url === does not work for me: Uncaught ReferenceError: url is not defined – Zoker Sep 27 '14 at 15:16

To elaborate further, since I cannot comment...url will return undefined without first defining it (you will notice Zoker's comment above).

To define url, you can do this:

var url = $(location).attr('href');

Then you can proceed to perform the check:

if(url === 'yourspecifiedurl.com'){
     window.location.href = 'yournewurl.com';
     return false;
}

Additionally, you do not need to use window.location.href as window.location will suffice. It defaults to window.location.href

A final thought, you can also use replace:

window.location.replace('theurltodirectto.com');
