I am loading some comments in via ajax, default is 5 onload then the user can request more if they want.
This is more a question of good practice.
Where is the best place to build to html elements that will be displayed on the page.
Should I build them up in the javascript file then display them?
I am using Yii framework if this is any help.

There are certainly a number of ways you can achieve this. I've faced a similar issue before (also related to a Comments system) and what I did was to create a custom Widget and simply load it in the controller. Widgets can have view files which will be loaded upon request and you can simply inject the output into a specific place in your page. Here's what I have in my code:
/protected/widgets/LoadComments.php
class LoadComments extends CWidget {
public $offset;
public $limit;
public $comments;
public function run() {
//(some offset and limit logic here)
$criteria = new CDbCriteria();
// some criteria definitions here (...)
$this->comments = Comment::model()->findAll($criteria);
$this->render('listComments', array());
}
}
/protected/controllers/CommentController.php
public function actionListComments($offset = 0, $limit = 10) {
$this->widget("application.widgets.LoadComments", array(
"offset" => $offset,
"limit" => $limit,
));
}
/protected/views/comments.php
<div id="comments"></div>
<script>
$(document).ready(function(){
$.ajax({
type: 'GET',
data: { offset : 0, limit : 10},
url: '<?php echo Yii::app()->createUrl('/comment/listComments');?>',
success: function(data) {
$('#comments').html(data);
}
});
});
</script>
