Forum: Rails Spinoffs (closed, excessive spam) Extend element with Prototype's functions

Hi there. I have very specific problem with Prototype.

I'm getting selection of document and make a range from it. It's
simple. But I'm receiving not extended elements from
<range.startContainer>. Ok. That's fine. I would like to add
prototype's functions to this element.

var container = range.startContainer;
container = Element.extend(container); // NOT WORKS!
// container still not have Prototype function, like childElements ;-(

How to extend DOM element with Prototype properly?

P.S. In any case, I can live without this feature, but, as for me,
it's better to use Prototype anywhere ;-) but not browser specific
features ;-)

What is range.startContainer?  Are you sure it's an element?

Yes, it's an element

var container = range.startContainer;
alert(container.tagName); // OK

This elements from iframe, where Prototype is not loaded, so, I want
to extend element manually ;-)

This should work in browsers which expose "prototype" of host objects
(e.g. any recent gecko, webkit, etc.):

var r = document.createRange();
var proto = r.startContainer.constructor.prototype;

for (var prop in Element.Methods) {
  if (!Object.isFunction(Element.Methods[prop])) continue;
  proto[prop] = Element.Methods[prop].methodize();
}

Thanks, will try soon ;-)
