Very simple script in jQuery to find all the languages present in an HTML document. Useful for controlling the accessibility of documents. Improvements are welcome. #a11y Made to run from the browser development console

get_langs_in_html_document.js
// main lang
if ($("html").get(0).hasAttribute("lang")) {
var main_lang = $("html").attr("lang");
} else {
var main_lang = $("body").attr("lang");
}
console.log("Main language is "+main_lang);
// children lang
var langs = [];
$("*[lang]").each(function() {
var lang = $(this).attr("lang");
if ($.inArray(lang, langs) == -1) {
langs.push(lang)
}
});
console.log("Other languages found: "+langs);
