Hi Handoyo!

Well I wasn't able to fully understand the question since title says Ajax and in text you have not mentioned any ajax.

Well I'll explain how to use ajax with CodeIgniter. I'll be assuming u use JQuery and CodeIgntier.

Using Ajax with CodeIgniter is fairly simple. All you have to do is call the proper controller from Jquery.

for eg.

<input type="text" name="val1" />
<input type="text" name="val2" />
<input type="text" name="val3" id="val3" />
<input type="button" id="button" />

above is your view code now jquery:

$('#button').click(function(){
$.ajax({
url: 'http://domain/index.php/controller',
...
...
success: function(val){
$('#val3').val(val);
}
});
});

in codeigniter controller you can fetch the values and return result as a number by echoing it.

function controller()
{
 $val1 = $this->input->post('val1');
 $val2 = $this->input->post('val2');
 echo $val1 + $val3;
}

Thats it.
