Status: RESOLVED DUPLICATE of bug 133827

(Core :: DOM: CSS Object Model, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021207 Phoenix/0.5

http://demandred:10000/mozilla-bugs/XHTML-DOMBug/addFormHTML.jsp contains a page
sent as text/html. In that page, the "Hide Menu" and "Show Instruction" links do
what they are supposed to do - make various elements visible/invisible.

At http://demandred:10000/mozilla-bugs/XHTML-DOMBug/addFormXHTML.jsp, the same
page sent with a different mime type gives incorrect results.

Reproducible: Always

Steps to Reproduce:
1. Go to At http://demandred:10000/mozilla-bugs/XHTML-DOMBug/addFormXHTML.jsp
2. Click on "Show Instructions" link or "Hide Menu" link.
3. Observe behaviour

Actual Results:  
Link itself disappears

Expected Results:  
ID'd element should become invisible via the DOM-style interface.

How about a usable link that includes the full domain name?  ;)

Are there any errors in the JS console?

Sorry...the two full URLS are as follows:

XHTML Page (sent as text/html):
http://demandred.dynu.com:10000/mozilla-bugs/XHTML-DOMBug/addFormHTML.jsp

XHTML Page (sent as text/xml):
http://demandred.dynu.com:10000/mozilla-bugs/XHTML-DOMBug/addFormXHTML.jsp

There are no console warnings for the HTML version. For the XML version, the
following messages are displayed.

(for the "Hide Menu" link)

Error: uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLElement.innerHTML]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
http://demandred.dynu.com:10000/mozilla-bugs/js/stdLib.js :: toggleVisibility ::
line 47"  data: no]

(for the "Show Instructions link)

Error: uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLElement.innerHTML]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::

line 31"  data: no]

innerHTML is not supported in XML.

Looking at your code, you seem to be using visibility instead of display and
this forces you to muck with the markup to make the size of the box change...
just using display:none instead of visibility:hidden would help here.
