Based on the solution by Jason Bunting, here is what I use now.
The whole thing is for the jQuery tablesorter plug-in: For (nearly correct) sorting of non-English tables with tablesorter plugin it is necessary to make use of a custom textExtraction function.
This one:
'dd.mm.yyyy') to a recognized format ('yyyy-mm-dd')Be careful to save the JavaScript file in UTF-8 encoding or it won't work.
// file encoding must be UTF-8!
function getTextExtractor()
{
return (function() {
var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
var lookupLetters = {
"ä": "a", "ö": "o", "ü": "u",
"Ä": "A", "Ö": "O", "Ü": "U",
"á": "a", "à": "a", "â": "a",
"é": "e", "è": "e", "ê": "e",
"ú": "u", "ù": "u", "û": "u",
"ó": "o", "ò": "o", "ô": "o",
"Á": "A", "À": "A", "Â": "A",
"É": "E", "È": "E", "Ê": "E",
"Ú": "U", "Ù": "U", "Û": "U",
"Ó": "O", "Ò": "O", "Ô": "O",
"ß": "s"
};
var letterTranslator = function(match) {
return lookupLetters[match] || match;
}
return function(node) {
var text = $.trim($(node).text());
var date = text.match(patternDateDmy);
if (date)
return [date[3], date[2], date[1]].join("-");
else
return text.replace(patternLetters, letterTranslator);
}
})();
}
You can use it like this:
$("table.sortable").tablesorter({
textExtraction: getTextExtractor()
});
