js erreicht eine perfekte Kompatibilität mit den wichtigsten Browsern für die Konvertierung von RMB in Groß- und Kleinschreibung_Javascript-Fähigkeiten

/*Kleinbuchstaben in Großbuchstaben umwandeln*/

var xcc= "12.22";
document.write(xcc+"=>"+formatRMB(xcc)+"<br/>");

/*Großbuchstaben in Kleinbuchstaben umwandeln*/

var rrrr = "壹拾贰元贰角贰分";
document.write(rrrr+"=>"+parseRMB(rrrr));

Ausgabeergebnis:
12.22=>Einhundertzwanzig Dollar, zwei Cent und zwei Cent
Einhundertzwanzig Yuan, zwei Cent und zwei Cent =>12,22
