264302 - uncaught exception - Object cannot be created in this context - NS_ERROR_DOM_NOT_SUPPORTED_ERR

Status: VERIFIED DUPLICATE of bug 68193

(Core :: DOM: Core & HTML, defect)

Description

2004101006/trunk/W2K

While visiting this page, this error appears in JS console:
  Error: uncaught exception: [Exception... "Object cannot be created in this 
  context"  code: "9" nsresult: "0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)"  
  location: "http://c1.navrcholu.cz/code?site=69287;t=lb14 Line: 34"]

Page is rendered in Standards compliance mode, contains div with inline style
display:none and external javascript is trying to create img element inside it.

Maybe related to bryner's bug 60212, because bug 194648 with similar error was
duped against it.

Attachment: simplified testcase

"Simplified" would mean the JS is simplified too.  As it is, it's not clear
which part of the JS is responsible.  Is the <noscript> part needed, for that
matter?

Attachment: simplified testcase ?

Boris, is this better?

Comment 4

[Peter Van der Beken [:peterv]]

Document.write is not supported in XHTML.

Comment 5

So uncaught exceptions in Mozilla are okay? (just asking, because I think about
it as about errors).

Comment 6

[Boris Zbarsky [:bzbarsky]]

The exception is uncaught by the page, not by Mozilla.

Yes, Mozilla's behavior here is correct.  There is indeed an error, and it's an
error in the page -- it's trying to use document.write in an XHTML document.

Dup, actually...
