Callback

The function passed as a callback will receive the newly selected value as the first parameter:

$("select").selecter({
	callback: selectCallback
});

function selectCallback(value, index) {
    alert("OPTION SELECTED: " + value + ", INDEX: " + index);
}
Demo
get selecter_callback_value

Disabling

Selecter will automatically detect disabled fields, but you can always manually trigger the disable or enable event:

$("select").selecter("disable");

$("select").selecter("enable");
