Simple ajax functionality in CI

Well, if all you want to do is fetch a name, you don't need ajax, just do this

Code:

<input name="cname" type="text" value="<?php echo $name;?>" />

, but I don't htink it's just what you meant. Ajax request you'd get like this:

Code:

$(document).ready(function() {
        $('input[name="cbutton"]').bind('click', function() { //bind your element to a click event
            $.get("controllername/ajaxrequest", function(data){ //get your data, use post instead if you're sending anything
                $('input[name="cname"]').val(data.name); //in the end, assign the value to the element, use just data in case you don't json_encode it on the other end
            }, 'json');
        });
    });

and for controller:

Code:

public function ajaxrequest()
    {
        $data['name']="Somename";
        echo json_encode($data); //comes in handy to use json when you deal with more than one variable, for just this one you could just echo;
    }

you could simplify this quite a bit if you used id in addition to name tag in your inputs. It's also a bit faster, cause the selector engine does less work.
