Extend HTMLElement

[Christopher Benson-Manica]

How do you extend HTMLElement? Why can't you just do

HTMLElement.pro totype.foo=func tion() {
alert( 'foo' );
}

I assume HTMLElement belongs to some kind of namespace, but darn if I
can find anything that tells me anything about it.

You can, but only in some user agents. Host objects are not required
to act like native objects. In some respects, IE is particularly
restrictive in the way in which it treats host objects to the point of
being, in my opinion, unreasonable.

It would be safer to create a function that accepts a reference to an
element.

In user agents that provide it, it will be a property of the global
object.
