Hi everybody!! I a newbie for CodeIgniter. I would like to ask all you guys.
I have to table in databases,
tb_customer and
tb_customer_site. Firstly, I query customer name to show in first drop-down list (as below code). I want to do that once I select customer name, system should query site name for that customer and show in the second drop-down list without refresh page. I understand that I can use onChange() in 4th parameter of form_dropdown(). I already test by alerting some text but It dose not work.
##My controller
Code:
//Query CUS_CODE and CUS_NAME from TB_CUSTOMER
$query = $this->db->get('tb_customer');
$result = array();
//Assign query result to dropdown list
$result['0'] = '- - - Select One - - -';
foreach($query->result_array() as $row):
$result[$row['CUS_CODE']] = $row['CUS_NAME'];
endforeach;
$data['listCusName'] = $result ;
//Send all parameters to view section
$this->load->view('mrtg_frm',$data);
##My view
Code:
<?
$js = 'onChange="alert("Hello World");"';
echo form_dropdown('mrtgCusName', $listCusName, '0', $js);
?>
Thank you your kind. ^^
