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

Another (apparently older) option is to use the format: "document.nameOfTheForm.nameOfTheInput.value;" e.g. document.mainForm.rads.value;

document.mainForm.onclick = function(){
    var radVal = document.mainForm.rads.value;
    result.innerHTML = 'You selected: '+radVal;
}

You can refer to the element by its name within a form. Your original HTML does not contain a form element though.
