RIA con Python...

Jue Ago 30 23:54:09 CEST 2007

 Hola :-)
 Buscando información y trasteando he conseguido desarrollar el ejemplo RIA 
(Rich Internet Application) de "mini-calculadora" para CherryPy2.2.1; así 
que funciona bien en TurboGears 1.
 RIA, RIA con Python. :-))
  He aquí el código; espero que os sea útil, saludos.

z.innerHTML = req3.responseText;
z.value = req3.responseText;

var url = "/multip?x=" + x.value + ";y=" + y.value;
req3.open("GET", url, true);
req3.send(null);
