[Proto-Scripty] Re: How do you add methods to Form.Element

I have this little bit of fluff:
Element.addMethods({
addText: function(input, theText) {
if(typeof input.selectionStart != 'undefined'){
var start = input.selectionStart;
var end = input.selectionEnd;
input.value = input.value.substr(0, start) +
theText +
input.value.substr(end);
input.selectionStart = start + theText.length;
input.selectionEnd = start + theText.length;
input.focus();
}
}
});
But I want to add it only to Form.Element. I tried just tacking
`Form.` onto the front of this, but all I got was a syntax error.
Could someone clue me in how to add this method only to Form.Element?
(Obviously, it doesn't make much sense in a regular Element context.)
Form.Element.Methods.addText = function(){ /* ... */ };
Element.addMethods();
