No dice.

The dump routine just dumps all the properties and methods so I could try to track my way throw the collections (thought it might be useful). <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN"> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=ISO-8859-1' /> <title>Frame A</title> <script language='JavaScript' type='text/javascript'> function tryThis(node) { if (node.document) { node.document.frames.parent.justForGrins("Internet Exploder"); alert(node.document.frames.parent.window); } else if (node.ownerDocument) { node.ownerDocument.defaultView.parent.justForGrins("NetScrape"); alert(node.ownerDocument.defaultView.parent.window); } else { alert("SOL"); } } function dump(myObj) { if (myObj == null) { document.write("null<br>"); } else { document.write("<table border=\\"3\\">"); document.write("<tr><th>Property</th><th>Value</th><th>Type</th></tr>"); for (var i in myObj) { document.write("<tr>"); document.write("<td width=\\"200\\">" + i); document.write("<td width=\\"200\\">"); if (myObj[i] != null) { if (typeof(myObj[i]) == "string") { document.write("\\"" + myObj[i] + "\\""); } else { document.write(myObj[i]); } } else { document.write("null"); } document.write("<td width=\\"100\\">" + typeof(myObj[i])); } document.write("</table>"); } document.write("<br>"); } </script> </head> <body> Frame A Contents <form name='myform' action='framea.html'> <input name='fred' type='button' value='say' onclick='tryThis(this);' /> </form> <script language='JavaScript' type='text/javascript'> var node = document.getElementsByName("fred").item(0); dump(node); if (node.document) { dump(node.document.frames.parent); } else { dump(node.ownerDocument.defaultView.parent); } </script> </body> </html>

Post #6,633 by ChrisR 8/24/01 3:00:55 PM Reply	Natch Figured as much, but just wanted to complete the thought. :-) Looks like the defaultView property may become a w3c standard sometime down the road. One thing that stuck out, though, is that I couldn't find the ownerDocument property in IE5.5 and that is part of the core DOM standard. And Opera JavaScript still seems to be lagging. I gather y'all are standardizing on the latest builds of Mozilla. Out of curiosity, what IE version are they using? I still have some apps that have to go back to navigator 2.x and ie 3.x, though I'm not sure anybody is still out there using them.
Post #6,677 by admin 8/25/01 3:34:12 PM Reply	Still some problems with DOM in IE 5.5 NOt nearly as bad as the incompatibility problems of the past, but still annoying. IE treats element attributes completely differently than Mozilla. Mozilla uses the W3C method of treating attributes as child nodes of the element; IE treats the attributes as a mapping on the element. Regards, -scott anderson
