Hi I'm new in codeigniter so this is the problem

I want to add prefix to textbox based on selected value in dropdown menu here's the source

In Controller

function index(){

    $data['title'] = 'SIPPERTIKOMPPAK|Input Barang';

    $data2 =array(

        'kode_barang' => $this->m_master->kode_barang(),

        'get_lokasi' => $this->m_master->get_lokasi(),

        'get_jenis' => $this->m_master->get_jenis()

    );



    $this->load->view('backend/preload/meta',$data);

    $this->load->view('backend/preload/head');

    $this->load->view('backend/preload/sidebar');

    $this->load->view('backend/master/v_masterb',($data2));

}

In Model

function kode_barang(){

        $kode= $this->db->select_max('id_barang')->get('tb_master_barang')->result_array();

        $qkode = array(); 

        foreach($kode as $r) { 

            $qkode = $r['id_barang']+1; 

        }

        $qkode=str_pad($qkode,3, '0' , STR_PAD_LEFT);

        // $qqkode = 'PRINJ'.$qkode;

        return $qkode;

    }

In View

<div class="form-group">

<label for="kode_barang">Kode Barang</label>

<input type="text" class="form-control" name="kode_barang" value="<?php echo $kode_barang; ?>" readonly />

</div>

<div class="form-group">

<label for="get_jenis">Jenis Barang</label>

<?php echo form_dropdown('id_jenis', $get_jenis, '', 'class="form-control"');?>

</div>

I want to add prefix to textbox for example like this

if id_jenis ==1

textbox.value = 'Prefix'+($qkode value from model)

else

textbox.value = 'Prefix'+($qkode value from model)
