ajax

<script>
function getValue(val) {
  //alert(val);
    $.ajax({
    type: "POST",
    url: "<?php echo base_url()?>moderator/RFQ/addrfqoffline",
    data:'reqid='+val,
    success: function(data){
             alert(data);
        $("#txtproduct").html(data);
    }
    });
}
</script>

First create an empty div in the page where you want to display the content.

 <div id="content"></div>

Next, change your controller function like this

function addrfqoffline() {
    $content = "";
    $this->load->helper(array('form', 'url'));
    $content = $this->load->view('moderator/templates/header','',true);
    $content .= $this->load->view('moderator/templates/sidebar','',true);
    $rid = $this->input->post('reqid');        
    $requirement = $this->requirement_model->viewdata($rid);
    $data['customers'] = $this->userdata->usersname();
    $data['merchants'] = $this->merchant_model->merchantname();
    // $data['mroproducts']=$this->mroproduct_model->mroproductname();
    $data['units'] = $this->requirement_model->fetchunits();

    if ($requirement) {
        foreach ($requirement as $reqdata) {
            $dat['reqid'] = $reqdata->rqm_id;
            $dat['service'] = $reqdata->rqm_service;
            $content .= $this->load->view('moderator/mrorfqnew', array_merge($dat, $data),true);
        }
    }
    $content .= $this->load->view('moderator/mrorfq', $data,true);
    $content .= $this->load->view('moderator/templates/footer',true);
    echo $content;// this will echo the view here
}

Now in ajax success,

success: function(data){
    $("#content").html(data);
}

This should help you.
