No need for ajax or special CI feature, just use simple [removed])

I have the impression, that people tend to forget about old school coding whenever they hear "...framework..." ^^

Try something along this lines:

Code:

<5cr1pt >
function update_disc_price()
{
  var new_value = $('price').getValue() - $('discount').getValue();
  $('disc_price').setValue(new_value);
}
</5cr1pt >
&lt;input name="price" id="price" value=""&gt;
&lt;input name="discount" id="discount" value=""&gt;
&lt;input name="disc_price" id="price" value="" /&gt;

Be aware, that this example uses the prototype framework and this can be done with "normal" js aswell, but I'm just to lazy to look the functions

My example propably won't work, but you should be able to work with this...I guess.

You're _really_ over-complicating this. Just use a little bit of old-fashioned [email protected]
