How to get value of selected radio button?

Question

I want to get the selected value from a group of radio buttons.

Here\'s my HTML:

Answer 1

directly calling a radio button many times gives you the value of the FIRST button, not the CHECKED button. instead of looping thru radio buttons to see which one is checked, i prefer to call an onclick javascript function that sets a variable that can later be retrieved at will.

which calls:

var currentValue = 0;
function handleClick(myRadio) {
    currentValue = myRadio.value;
    document.getElementById("buttonSubmit").disabled = false; 
}

additional advantage being that i can treat data and/or react to the checking of a button (in this case, enabling SUBMIT button).
