Post #152,095 by JayMehaffey 4/21/04 2:52:15 PM Reply	Re: comments, and thanks You mean make a reference object first rather than one big dotted path thingy? I'll give it a try. (Damn, I wish DOM was relational.) No, what I meant is that using the name of the form in the code the way you did seems to be an IE only thing. I was thinking something like opener.document.forms[0].select1[1].selected would work, but opener.getElementByID is probably better. In any case here are two simple examples I hacked up to test it making calls across windows. Jay

Post #152,122 by tablizer 4/21/04 8:32:43 PM Reply	Thanks, works with "document" in there. It works in Mozilla when I put "document" in the expression. I am still fuzzy on the relationship between Window and Document in DOM. It looks one-to-one to me. If so, it is bad normalization it would seem. Is it possible to overlap documents, such as in layers? ________________ oop.ismad.com
Post #152,154 by JayMehaffey 4/21/04 9:48:36 PM Reply	I don't think so I don't think a window can ever have multiple documents, as both layers and frames are handled as parts of a document. It is possible it have a window with no document, but it's not very common. It's probably that way because the guys that did the early Netscapes had some object oriented experience. Seperating the Window object and the Document object despite their near perfect unity is very OO. Jay
Post #152,156 by ben_tilly 4/21/04 10:00:46 PM Reply	Windows can have many documents The current document, the previous document, the one previous to that... That nobody ever chose to expose this doesn't mean that it was a bad initial idea to have made it possible to choose to do so. Incidentally the frames array belongs to a Window, and not the Document. (Or at least used to.)

Post #152,235 by drewk 4/22/04 2:12:55 PM Reply	Another reason for it You can pop up a new empty window with javascript, and then dynamically write contents into it. Until you've written something into it, the window has no document. There are probably also some theoretical guidelines on closing the window for writing before the document exists in the DOM, but considering how loosely browsers interpret invalid code I wouldn't bet on those guidelines ever having been followed. === Implicitly condoning stupidity since 2001.
