FAQ Topic - Why does my code fail to access an element?
-----------------------------------------------------------------------

An element can only be accessed after it exists in the document.

Either:
A) include your script after the HTML element it refers to, or
B) use the `"load"` event to trigger your script.

Example A:

<div id="snurgle">here</div>
<script type="text/javascript">
// Don't forget var.
var snurgleEl = document.getElementById("snurgle");
window.alert(snurgleEl.parentNode);
</script>

Example B:

// In the HEAD.
<script type="text/javascript">
window.onload = function(){
var snurgleEl = document.getElementById("snurgle");
};
</script>

Other problems can include::
----------------------------

* invalid HTML

* two elements with the same `name` or `id`

* use of an unsafe name: http://jibbering.com/names/

The correct URL is
http://jibbering.com/faq/names/

But I’m afraid the FAQ is frozen (and soon frozen to death). There’s 
little point in trying to keep it, or this group, alive. That’s sad, 
because there is a lot of useful stuff in the FAQ.

The most constructive approach would be to write a new JavaScript FAQ, 
making use of the information in comp.lang.javascript but breaking any 
connection to this group, and to find a good home for it. By good home, 
I mean connecting it with an active, constructive forum.
