better shoutbox rendering

/media/mod_shoutbox/js/mod_shoutbox.js

function JJShoutbox.getPosts

var request = {
			'option'         : 'com_ajax',
			'module'         : 'shoutbox',
			'method'         : 'getPosts',
			'format'         : 'json',
			'jjshout[id]'    : lastID, /* add last id */
			'jjshout[title]' : params.title,
		};

disable 	//params.instance.find('#jjshoutboxoutput').empty().prepend($('<div class="jj-shout-new"></div>'));

Change from:  //params.instance.find('.jj-shout-new').after(response.data.html + historyButton);

to: $('#jjshoutboxoutput .jj-shout-new').after(response.data.html) 


and changed in helper:

/modules/mod_shoutbox/helper.php

function getPostsAjax()

added var $post["id"] like	$shouts = $helper->getShouts($offset, $helper->getParams()->get('maximum'), JText::_('SHOUT_DATABASEERRORSHOUT'), $post["id"]);


function getShouts($offset, $number, $message, $id) /* add $id */
try
		{
			$shouts = $this->getShoutData($offset, $number, $id); /* add $id */
		}


function getShoutData($offset, $number, $id) /* add $id  */

$query = $this->db->getQuery(true)
		->select('*')
		->from($this->db->qn('#__shoutbox'))
		->order($this->db->qn('id') . ' DESC')
		/* only Shout IDs greater then last known lastID */
		->where($this->db->qn('id') . ' > ' . (int)$id)
		//
		->setLimit($number, $offset);
