A simple form with 2 controls: one text, one image, should appear in
Javascript:
form.elements.length == 2
But image controls don't appear in the elements collection. Why not?
Reproducible: Always
Steps to Reproduce:
Display this file in a browser:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html><head><title></title><script type="text/javascript">
function ecount() {
alert("length="+document.getElementById('formid').elements.length);
}
</script></head><body onload="ecount()">
<form id="formid" action=""><p><input type="text" name="textinput">
<input type="image" name="imginput" src="image.png"></p></form>
</body></html>
Actual Results:
An alert box saying "length=1"
Expected Results:
An alert box saying "length=2"
For what it's worth, all other browsers I've checked (Opera/Win,
IE/Win, Safari/OSX) exhibit the same behavior. But the spec
(at http://www.w3.org/TR/DOM-Level-2-HTML/html.html) says:
elements of type HTMLCollection, readonly
Returns a collection of all form control elements in the form.
There's no mention of excluding certain types of controls from
the collection. Neither is there any mention of discrimination
against image controls in the HTML spec:

That's not a concidence. The de-facto standard is that image inputs don't
appear in form.elements, and it's implemented interoperably by all browsers.
Doing anything else would break far too many pages.
