Passing more parameters in Ajax_pagination in CodeIgniter 3.0 - ajax

Question

I am using Ajax_pagination library in CodeIgniter 3.0.The pagination is working fine.Now i want to pass more parameters with page itself.
For Example I have a page where User select Country and Category.Now i want to show data with pagination.Here is my code.
function ajaxPaginationData()
{
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$totalRec = count($this->post->getRows());
//pagination configuration
$config['first_link'] = 'First';
$config['div'] = 'postList'; //parent div tag id
$config['base_url'] = base_url().'index.php/posts/ajaxPaginationData';
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->perPage;
$this->ajax_pagination->initialize($config);
$data['posts'] = $this->post->getRows(array('start'=>$offset,'limit'=>$this->perPage));
$this->load->view('posts/ajax-pagination-data', $data, false);
}
Here is my pagination html
<div class="pagination">Showing 1 to 5 of 8 | <b>1</b> <a onclick="$.post('http://localhost:8080/ajax/index.php/posts/ajaxPaginationData/5', {'page' : 5}, function(data){
$('#postList').html(data); }); return false;" href="javascript:void(0);">2</a> <a onclick="$.post('http://localhost:8080/ajax/index.php/posts/ajaxPaginationData/5', {'page' : 5}, function(data){
$('#postList').html(data); }); return false;" href="javascript:void(0);">></a> </div>
Now On Change of country dropdown I want to get list with that Id
<select id="country">
<option value="0">select</option>
<option value="1">USA</option>
<option value="2">UK</option>
</select>

Pass the value of your dropdown in function
function ajaxPaginationData($country)
{
$page = $this->input->post('page');
if(!$page){
$offset = 0;
}else{
$offset = $page;
}
$totalRec = count($this->post->getRows());
//pagination configuration
$config['first_link'] = 'First';
$config['div'] = 'postList'; //parent div tag id
$config['base_url'] = base_url().'index.php/posts/ajaxPaginationData';
$config['total_rows'] = $totalRec;
$config['per_page'] = $this->perPage;
$this->ajax_pagination->initialize($config);
$data['posts'] = $this->post->getRows(array('start'=>$offset,'limit'=>$this->perPage));
$this->load->view('posts/ajax-pagination-data', $data, false);
}
And use $country to select the data from table with where condition.
