JAVASCRIPT get current language!!!

Hi
"window.location" has what's in the address bar of your browser.
If that doesn't work, try window.location.href. you might want to do some parsing in javascript level to get exactly what you need

also you can pass the variable from module file and use it in js file.
e.g.

$js_variables = array(
'first_var' => arg(1),
'second_var' => $url_lang,
);
drupal_add_js(array('modulename' => $js_variables), "setting");

and access it using
var js_first_var = Drupal.settings.modulename.first_var;
var js_second_var = Drupal.settings.modulename.second_var;

thanks,
Shashikant.
