How to get the value of a radio button within a radio button group when selected using JQuery

Give all the radio buttons within a group the same name

<input type="radio" name="RADIOGROUP" value="1" />
<input type="radio" name="RADIOGROUP" value="2" />
<input type="radio" name="RADIOGROUP" value="3" />
<input type="radio" name="RADIOGROUP" value="4" />

Now use the following JQuery code to obtain the value for the selected radio button within the Group

$("input[name=RADIOGROUP]").change(function(){
        alert($(this).val());
 });
