change

The change event is fired when slider changes its value.
The new slider value is transmitted as an event argument - event.value.

<input id="slider" value="30" />

<script type="text/javascript">

     $(function () {
        $("#slider").shieldSlider({
            events: {
                change: function (event) {
                    alert("Slider value: " + event.value);
                }
            }
        });
     });

</script>
