Get selected radio button value in javascript

I have dynamically created radio buttons and have assigned them ids. Now when i try,

function updateAO(id2) {
    var status = $('input[name=id2]:checked').val();
    alert(status);
}

It prints undefined. Can anyone please tell how to get this value. Thanks in advance!!

To get the selected radio button value use 

function updateAO(id2) {
    var status = $('input[name=id2]:checked').val();
    alert(status);
}

To select normal radio button use

function updateAO(id2) {
    var status = $('input[name=id2]').val();
    alert(status);
}

The :checked selector will only select inputs currently checked, if the passed input isnt checked at the time, status will remain unset, try changing your JS to:

function updateAO(id2) {
    var status = $('input[name='+id2+']').val();
    alert(status);
}

You're not using your parameter correctly.

var status = $('input[name="' + id2 + '"]:checked').val();
