Are there any javascript/DOM gurus out there who can tell me why the html
page below finds the <p> tag and the <div> tag but ignores the <a> tag.

Below is the html being tested.

<body>

<p   id='m'></p>

<a   id='a'></a>
<p   id='p'></p>
<div id='v'></div>

<script type='text/javascript'><!--//
var d = document;
var m = d.getElementById('m');
var a = d.getElementById('a');
var p = d.getElementById('p');
var v = d.getElementById('v');
var b = '<br />';
m.innerHTML = a+b+p+b+v+b;
//--></script>

</body>
</html>


will it's simple ,
what do you want to get from the getElementById('')?
I mean if you're trying to know what kind of element is it, just to process
it in some how, then you will not get a result from just using the
getElemntByid thing for example:

d.getElementById('p');
will return in Firefox: [object HTMLParagraphElement]
in IE Mac: [object P]

why don't you just specify what you want to get back from it let's say you
may use:

 var a = d.getElementById('a').innerText;
by the way adding href="" to the anchor tag will let  var a =
d.getElementById('a'); return the href it self, if you still need an output
that looks like:
[object HTMLanchorElement]

tell me and will find a work around for you...

Thanks for your generous offer, Bassel.

I need the node so I can use "nextSibling".

What I'm trying to accomplish is to "display:none" or "display:block" the following element whenever the <a> is onclicked.

As you pointed out "document.getElementById()" returns not the id, but the href. (That really puzzles me and differs from the O'Reilly books on Javascript and Dynamic HTML).

Is this a known bug? If it is I will have to wrap my tags in such a way that I can find the other node relative to it some other way.

If you have ideas I'm eager and open eared :)
