You could declare, after the list of comment, an empty "comment" for
future insertion :
<div id="last_comment"></div>
Then in your view, make a javascript block :
$last_post = '<p>'.$comment.'</p>'; // format the display of your
comment
$last_post .= '<div id="last_comment"></div>'; // add a new place
holder for last_comment
$last_post = str_replace(array('%','/','<',"\\","\r","\n",'"'),
array('%25','\/','%3C','\\','','\r\n','\"'),
$last_post); // escape the inserted html
$last_post = 'unescape("' . $last_post . '")'; // add unescape in
javascript
$js = "elem = $('last_comment'); Element.replace(elem,
'{$last_post}');"; // replace the last_comment by the html comment
+ a new div
echo $javascript->codeBlock($js); // echo the javascript
Basically in the above, you replace the last_comment div, by the post
(html) and you add again a last_comment div (for next post) ..etc ..
The code here, is to give you an idea, you have "escape" the Html,
that's why I do the str_replace and the unescape after..
I just wrote this without testing the above code, I hope this helps
