Add the class "pnradio" to the radio buttons, then switch with .attr('id')
<input type="radio" id="sampleradio1" class="pnradio" />
<input type="radio" id="sampleradio2" class="pnradio" />
$('.pnradio').click(function() {
switch ($(this).attr('id')) {
case 'sampleradio1':
alert("xxx");
break;
case 'sampleradio2':
alert("xxx");
break;
}
});
