[SOLVED] JS not enabled

[williamZanelli]

Hi guys,

 

I've coded a website, which has alot of JS, as in when someone hovers over the image it expands in size, a caption etc appears.

 

I've realised that 3% of people from my analytics data) who come to my website, dont have JS enabled, what I want is to redirect these guys to a non-JS website,

 

Any ideas on how I go about this? Can someone please post some examples..?

 

Regards

The best method that I know of is to set a cookie via javascript and then check it in php. If the variable isn't present and they aren't a search engine crawler  redirect. That and noscript tags to notify them that javascript is required.

Thanks for the reply Tom,

 

I was wondering if you had any example code.. I'm not much of a programmers.

 

Cheers.

Just set the cookie with javascript with setcookie(); and then check if it exists like this:

 

<?
if (isset($_COOKIE['javascript'])) {
    //JS is enabled
} else {
   //JS is not enabled.. redirect.
}
?>

 

I'm gonna assume you know how to set a cookie with JS since you *did* code the website using JS. Otherwise you can just look it up or something.

Thanks for the reply guys,

 

But i;m still not 100% with your logic,

 

So say a new user (never accessed my website in his life) types in my URL, if the JS is enabled it sets the cookie, I then check in PHP if its enabled, if it is.. ok, otherwise redirect.

 

My point of question lies in that, does the JS get called before the PHP? I was always under the impression the PHP is called first, which would mean, when the check is carried out for a new user, the Cookie is never enabled?

 

Am I right?

 

Thanks in advance for your thoughts...

You're correct. I'd say in your situation best thing you could would be something like:

 

<noscript><meta http-equiv="refresh" content="0; url=non_js_page.php"><a href="non_js_page.php">Non-JS page...</a></noscript>

On the first request set a session variable. Then check for the cookie.

That wouldn't be valid html. The meta tag is not allowed within the body and the noscript tag is not allowed within the head.

I think he's asking how though as JS runs after the page has loaded, which means that to test PHP-side for a cookie set via JS, you could only do it on the second request?

 

..and I didn't know that, cheers!

Personally I would just use a noscript tag with a link to the non js version.  If they have javascript disabled (not a search engine or some other type of bot) they most likely already understand that a lot of functionality from a lot of sites is going to be missing. What if they disable CSS? Do we have to support that as well?
