How to get value from controller with jquery - keziaendhy - 06-27-2017
Controller :
function auto_barang(){
$id=$this->input->post('id');
$res= $this->barang_model->get_autocomplete($id);
//foreach ($res as $rows){
// $hasil['stock']=$rows['stock'];
//}
//$this->output->set_content_type('application/json');
$this->output->set_output(json_encode($res));
}
Script :
<script>
$(document).ready(function(){
$("#barang").change(function(){
$.post("<?php echo base_url()."index.php/pembelian/auto_barang"; ?>",
{
id:$("#barang option
elected").val()}, function(data){
alert(data);
});
});
</script>
Output :
[{"id":"2","nama":"Lenovo ideapad 200","harga_beli":"2000000","harga_jual":"2500000","stock":"5"}]
How to if I just want to take stock value? Thank you !

Try this:
PHP Code:
$this->output->set_content_type('application/json')
echo json_encode($res);

Oh! I did not know that (set_content_type).
Is that important?
When I ajax with a json response in the controller I just json_encode the array and echo it. It has all worked fine up till now.
Should I be setting the content type as well?
Paul.
PS the gaps in my knowledge continue to amaze me :-)

The newer browser should know what type it is but I use it just to be safe.

If you just need one field then just output that one field
$this->output->set_output(json_encode($res['stock']));

I always do things like get result from query as array such as result_array() for multi dimension or single array like row_array() then simply
For example , in your case, I would do this
$res= $this->barang_model->get_autocomplete($id); //assume you get row_array as return
then
echo json_encode($res);
OR I usually wrap it up with success and message, data like this:
echo json_encode(array('success'=>1, 'message'=>'anything you want to read', 'data'=>$res));
My frontend at ajax, I often using
Code:
$.post(yoururl,{optionaldata},function(result){
//you can check result data here
},'json') //make sure you have 'json' to indicate that you need json as content type !
.done(function(result){
//I often do this here
if(result.success===1){
console.log(JSON.stringify(result.data));//show all your json string as data
console.log(JSON.stringify(result.data.stock)); //will show your stock value !
}
})
.fail(function(result){
//action for failures so on
});
