Uncaught Exception... I have no clue about.

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004001
(NS_ERROR_NOT_IMPLEMENTED) [nsIDOM3Document.domConfig]" nsresult: "0x80004001
(NS_ERROR_NOT_IMPLEMENTED)" location: "JS frame ::
file:///D:/sites/_test/js/iterate_document.htm :: <TOP_LEVEL> :: line 15" data: no]

Line 15 being:

s += j + ". " + i + ": " + document[i] + "<br />\n";

All the code:

s = '';
j = 1;
for (i in document)
{
s += j + ". " + i + ": " + document[i] + "<br />\n";
j++;
}

In Mozilla Firefox it prints a nice 136 item long list, but also throws that error up.
Can anyone explain to me what it means and why it popped up?

Many thanks in advance.

Dood,

This issue is caused because you are adding document[i]. This forces the
javascript engine to call the default toString method for each element in
the document. It there is no default toString method for a aparticular
element an error will be thrown. In the case of the MS javascript engine,
that error is 'not implemented'.

Just put a try block around the troublesome statement and make it add some
indicative text like 'unknown' instead if an error is thrown.

Cheers

AJ
