How to check HTTP_ACCEPT_LANGUAGE using Javascript?

[Edo van der Zouwen]

It's quite easy in Php:

<?php

$language = $_SERVER['HTTP_ACCEPT_LA NGUAGE'];
$language_short = substr($taal,0, 2);

echo $language_short ;
?>


But would love to do it in Javascript..... .

Anybody?

Many thanks in advance!!

IE extends the navigator object with two properties you could reference:

navigator.syste mLanguage
navigator.userL anguage

Doesn't work in other browsers and I'm not shure whether this would work on
a mac or not...

Gecko based browsers look like they use

navigator.langu age

My reference says this goes back to NN4.

.... this doesn't seem to give exactly what the ACCEPT_LANGUAGE header
would have, but it might be close enough ...

Thanks for both replies. However. the .userlanguage .browserlanguag e or
..systemlanguag e properties give the language of the browser or system.

In a browser, you can however also set the 'preferred language' in which
you can see a webpage.

For example, many people outside the US or UK have an english browser,
but would like to see webpages in their home language. This can not be
solved by using the properties above.

Any more ideas?

Thanks,


Edo.


P.S. By the way, for those interested, this is the code for checking the
browser language:

(example for dutch, polish and english users, which will be directed to
index_en.html, index_pl.html or index_nl.html)

<SCRIPT LANGUAGE="JavaS cript1.2"><!--
// The following only works in JavaScript 1.2 or greater:
function showpage(code) {

location = ("index_" + code + ".html");
}


if (navigator.appN ame == 'Netscape')
var language = navigator.langu age;
else
var language = navigator.brows erLanguage;

var code = language.substr ing(0,2);

if (code == 'pl' || code == 'nl' || code == 'en')
showpage(code);
else
showpage('en');
//--></SCRIPT>

As far as I know, the HTTP request & headers sent with the request are
not accessible to javascript. This is probably (my guess) because these
are formed immediately before transmission and too late for server-side
scripting to make use of.

I believe I mentioned before, my prefered solution would be to use the
content-negotiation capabilities of HTTP 1.1 and configure the web
server to handle the content decision-making. How to do this is beyond
the scope of this NG, which is fortunate for me because it is presently
also beyond the scope of my knowledge. :-)

Sorry I've no further suggestions.

Thanks for your input.

Cheers,

Re: How to check HTTP_ACCEPT_LAN GUAGE using Javascript?

I have found the following solution, which is a combination of php and
Javascript.

Look at how the variable from php is passed onto Javascript.

This code is based on the following input for the propertie:

http://www.weijers.net/sitemap.html

and the following for passing the variable:

http://www.sitepointforums.com/showthread.php?threadid=106385

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitl ed Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>

<?php

$preflanguage = $_SERVER['HTTP_ACCEPT_LA NGUAG E'];
#Check the property


$lang = substr($preflan guage,0,2);
#Take the first 2 characters

if ( $lang == "nl" or $lang == "en" or $lang =="pl")
{
$filename = "index_" . $lang . ".html";
#create the filename to go to later

}

else

{
$lang = "en";
$filename = "index_en.html" ;
#create the filename to go to later

}

?>

<SCRIPT LANGUAGE=JAVASC RIPT>
location = ("<?php echo $filename; ?>");
//Let javascript redirect, using the php variable

</script>


</body>
</html>



I'm sure it isn't the most beautiful solution, but it works!

Edo.

I saw your solution, but just to correct my misstatement here: I meant
"too late for *client*-side scripting to make use of" ...

A very acceptable solution, here. Good digging.
This also prompts me to believe that using server-side includes you
could achieve the same thing:

<script type="text/javascript">
var acceptLang="<!--#echo var="HTTP_ACCEP T_LANGUAGE"-->"
// figure out which language by parsing "acceptLang "
switch(myLangua ge) {
case "nl":
...
break;
case "en":
...
break;
case "pl":
...
break;
default:
...
break;
}
// or something similar
</script>

Very like your PHP approach.
