RESOLVED - (d)html & javascript: using "this" and elements...

[deeperdish]

I have this javascript code:

<script type="text/javascript">
function disp()
{
	n = document.getElementById('btwo');	
	n.style.display=n.style.display=='block'?'none':'block';
}
</script>

And this html:

<tr id="two">
	<td><a href="javascript:void(0)" class="clink" onclick="disp()">Topic: Two</a>
		<blockquote id="btwo" class="DisplayNone">Some bumf about this topic</blockquote>
	</td>
</tr>

The bit in the blockquote is initially hidden, then when you click the link ("Topic: Two"), it shows the hidden bit (..toggles display style).

I need to un-hardcode the 'btwo' in the script part...

I tried using onclick="disp(this)" , but my knowledge of the DOM tree is pitiful...

Any help / hints appreciated.
Thanks
