How to get the selected radio button value using jquery ?

Demo on jsFiddle: http://jsfiddle.net/yrshaikh/H6bhE/

Html :

<input type="radio" name="gender" value="male">Male
<input type="radio" name="gender" value="female">Female
<input type="radio" name="gender" value="none">I dont want to disclose :)

<input id="submitBtn" type="submit" value="submit" />

Jquery :

$("#submitBtn").bind("click", function(){

    var myRadio = $('input[name=gender]');
    var checkedValue = myRadio.filter(':checked').val();

    alert(checkedValue);

});‚Äč

Another way of doing this would be…

$("input[name='gender']:checked").val()
