If/Else Statement

Samo

i'm just about ready to start my first javascript project, but there's one thing i need to know before i do it.

is it possible to make and if/else statement where if the else part is the active part that the javascript will exit and go into regular html mode so that in the 20% or so chance cae that the user has js disabled, they'll still be able to see the site? and if so, if the if part is the active part, will it do that and then the regular html part or just the if part?

I'm really trying to understand what you're saying... honestly... but I can't.

You mentioned "if the user has JS disabled". If they have it disabled, the entire script won't do a single thing. Instead, you might look at using NOSCRIPT tags.

Samo

read post #3 for explaination

and then post #7 if u understand

bradgrafelman has already given you your answer.

Yeh, you seem to believe that if javascript is disabled... it'll run the javascript else statement.

But it wont... because if javascript is disabled, it'll just skip over it completely.

The way one deals with this is, you create a regular HTML version of the site that includes a javascript redirect to the javascript version. If they have it disabled, they see the HTML version since the redirect will do nothing. And obviously if they have it enabled they'll be redirected to the JS version

use the noscript tag to catch people with javascript disabled if you want to display something different to them.

<script type="text/javascript">
//<![CDATA[
	document.write('<p>You have javascript enabled<\/p>');
//]]>
</script>
<noscript>
	<p>You have havascript disabled</p>
</noscript>

Bit cumbersome if he wants to code an entire JS free version of the site though. Means longer load time for everyone, if the page is complex and has a fair amount of code.

Seeing as though he's been extremely vague on what he wants to do, I thought I'd put it out there.

JPnyc

Agreed.

ok, here's is what i'm trying to do, i'm trying to make it so that if your screen res is smaller than 1024x768, a lower res version will be displyed AUTOMATICALLY

no here's the thing, i can make it so that if the user has javascript disabled, they will just get the regular, pure html 1024x768 version. that's the easy part. the problem is, i don't know if it's possible so that if js is enabled, they will only get the version that corresponds with their screen res instead of both tables

JPnyc

Using the method I mentioned, you can. Put the screen width detect script with a redirect into the 1024 version. If they dont have JS enabled, it will do nothing and they'll just get the 1024 version.

JPnyc

But why not just make the table width a % value? Doesn't that take care of it with no procedural coding?

Samo

yes, but then for any res larger than 1024, the images will be distorted. the page is graphical, not tables and colors

i would do ur idea, but i really want this to be 100% automatic. or, wait, r u saying that i make 2 versions of each page, and the js will automatically redirect to the % page?

JPnyc

Could do that, or you could use a JS function to change the images and table size if they have JS enabled and the res is a certain size. Whichever way you think is easier

Samo

can you walk me through that second thing u said?

JPnyc

Why don't you give me an url to the page so I can see exactly which approach is best.

Samo

it's not up yet and i don't have the ftp account

the best i'd be able to show you is a gif of the whole thing

JPnyc

Well that won't help. Let's try the reverse approach. Which of the methods mentioned do you feel you have the best shot at doing? There's not a whole lot of difference between them so whichever you feel you have the skills to do is the one you should try.

Samo

i'd be able to do them both just as esily, but i'd prefer to make it all happen on a single page so can you tell me how to do the second thing you said?

or if you want could upload temporarily into my personal ftp account so you could see
