[Rails-spinoffs] Prototype: Extend Form.Element

[Dan]

Hi everyone,

first, i'm new to Prototype. I want to extend Prototypes Form.Element
class with a few function like this:

Object.extend(Form.Element,{
          pointize : function(element) {
                if ($(element).present()) {
                        return element.getValue().sub(',','.');
                }
                return element.getValue();
          },
          toFloat: function(element) {
            if ($(element).present()) {
                return parseFloat(element.pointize());
            }
            return 0.0;
          },
          toInt: function(element) {
            if ($(element).present()) {
                return parseInt(element.pointize());
            }
            return 0;
          }
        });

But if i want to call one of these functions on an input element like $
(myInputElementId).toFloat() i always get an error that toFloat is not
a function... what do i wrong?


Thanx in advance!
Bye Dan
