Existe-t-il une fonction intégrée de JavaScript pour convertir une chaîne en une locale particulière (Euro dans mon cas) ?
Par exemple, 50.00 devrait être converti en 50,00 €.

Je travaille sur un site international qui traite de plusieurs devises.
Je ne voulais pas régler la Locale chaque fois que je voulais afficher une devise, alors j'ai fait un prototype qui formate la devise à la locale appropriée. Il est transparent dans ses conversions de sorte que vous pouvez le personnaliser à vos besoins ainsi.
Number.prototype.formatMoney = function(moneySymbol, decimalCharacter, thousandsCharacter, decimalPlaces, symbolLocation)
{
var symbolLocation = (symbolLocation == undefined || symbolLocation < 1 || symbolLocation == "begin")?"begin":"end";
var decimalPlaces = isNaN(decimalPlaces = Math.abs(decimalPlaces)) ? 2 : decimalPlaces;
var thisNumber = parseFloat(this, decimalPlaces);
var decimalCharacter = decimalCharacter == undefined ? "." : decimalCharacter;
var thousandsCharacter = thousandsCharacter == undefined ? "," : thousandsCharacter;
//var pm = thisNumber < 0 ? "-" : "";
var pm = "";
var pmB = thisNumber < 0 ? "(" : "";
var pmE = thisNumber < 0 ? ")" : "";
var i = parseInt(thisNumber = Math.abs(+thisNumber || 0)) + "";
var j = (j = i.length) > 3 ? j % 3 : 0;
var retString = pmB;
retString += ((symbolLocation == "begin")?((moneySymbol)?moneySymbol+"":""):"");
retString += pm;
retString += (j ? i.substr(0, j) + thousandsCharacter : "")
retString += i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + thousandsCharacter);
//alert((decimalPlaces ? decimalCharacter + (Math.ceil(Math.abs(thisNumber - i)*Math.pow(10, decimalPlaces))/Math.pow(10, decimalPlaces)).toFixed(decimalPlaces).slice(decimalPlaces) : "") + '\n' + Math.abs(thisNumber - i).toFixed(6));
retString += (decimalPlaces ? decimalCharacter + (Math.ceil(Math.abs(thisNumber - i).toFixed(6)*Math.pow(10, decimalPlaces))/Math.pow(10, decimalPlaces)).toFixed(decimalPlaces).slice(decimalPlaces) : "");
retString += ((symbolLocation == "end")?((moneySymbol)?moneySymbol+"":""):"");
retString += pmE;
return retString;
};
