Detect if Javascript disabled, if yes then redirect

Question

I'm having problems with detecting Javascript. I've created a jQuery Popup window which is working only for users who has javascript enabled. However if their browser has JS disabled, I'd like to redirect them to index.php WHEN they click on the button.

So basically if someone has JS enabled he/she would get the popup window, and if they don't have, they would have been redirected.

Is it possible? Also if would this work on mobile devices aswell?

If it's an a-tag, just provide a correct href – anderssonola Feb 13 '13 at 14:09 — anderssonola, Feb 13 '13 at 14:09

There is a meta tag that will allow you to do this, just keep in mind it can't go in the body and needs to be in the head of the document.

<noscript>
    <meta http-equiv="Refresh" content="0; URL=../error/errorjs.jsp" />
</noscript>

I would actually only need to redirect the person if they don't have Javascript enabled. – Taboo Loco Feb 13 '13 at 14:15
hence the noscript tags. it will ONLY redirect if javascript is disabled. – OnResolve Feb 13 '13 at 15:01

This technique is called hijax

Create a link <a href="index.php">..</a>

And attach to it a javascript event that disable the normal flow

If javascript is enabled, it will show the popup, otherwise the link will work as normal..

if you're using jQuery you can use `event.preventDefault()` to stop the normal functionality of an `` tag. http://api.jquery.com/event.preventDefault/ – Thomas Clayson Feb 13 '13 at 14:12
Could you please elaborate it a little bit more? I've just downloaded a jQuery popup window and I don't know where to paste what :/ – Taboo Loco Feb 13 '13 at 14:16
