In the following HTML, the line:

flash.focus();

causes this error in my Javascript console:

Error: flash.focus is not a function

Iterating through the properties of the element like so:

   for (var propName in flash)
   {
     output += propName + ", ";
   }
   alert("flash properties: " + output);

indeed shows no such method. How come?


Reproducible: Always

Steps to Reproduce:
1. open mozilla
2. open javascript console
3. hit above page

Actual Results:  
javascript error: focus is not a function

Expected Results:  
flash element (embed tag) should have been given focus
Nothing to do with events.  Why exactly should there be a focus() method there?
 Do you expect that to be present on all <embed>s or just Flash ones?
Assignee: events → general
Component: DOM Events → DOM Level 0
Why should there be a focus() method there? Well, I'd use for one if there were.
Why not?

All embeds I guess. (BTW, IE provides focus() on <object> tags, not that that in
itself is a reason).
Interesting.  In DOM2 HTML, <select>, <input>, <anchor>, <textarea> have focus()
methods, but <button> and <object> do not.  jst, that seems like an oversight to
me....
HTML 4 Button elements have an onfocus event attribute but not so for HTML 4
Objects.

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
