Only loosely speaking. What is returned is a *reference* to an object, and that reference is being *resolved* when the dot property accessor for the method is being evaluated. > What would you expect getElementById() to return? If there is no element with that ID, it is supposed to return the “null” value :) >> And in fact I don't understand what "document.getElementById" is in >> the FIRST place!!

No, instead the *method* “getElementById” is provided by an *implementation* of DOM *interfaces* that is in turn provided by the *layout engine*. The HTML document is *represented* in the DOM implementation (for historical and practical reasons) by an object referable by the identifier “document” (because there is an object in the scope chain that has a corresponding property of that “name” whose value *is* the reference to the former object). >> Well, I guess MY poor little brain can't match Brendan Eich's :) > > He only had 10 days in which to create JavaScript, he can be forgiven > for some of its vagaries... Brendan Eich was NOT responsible for the *W3C* DOM (but probably for its predecessor, the Netscape DOM). One must learn to mentally *separate* the programming languages and the (W3C) DOM (that can be used with them); the other way lies madness. -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail.
