<p>Here's a nice way to get the checked radio button's value with plain JavaScript:</p>

<pre><code>const form = document.forms.demo;
const checked = form.querySelector('input[name=characters]:checked');

console.log(checked.value);

<pre><code>&lt;form name="demo"&gt;

    Mario
    &lt;input type="radio" value="mario" name="characters" checked&gt;

    Toad

<p>lets suppose you need to place different rows of radio buttons in a form, each with separate attribute names ('option1','option2' etc) but the same class name.

<pre><code>&lt;script type="text/javascript"&gt;

    var ratings = document.getElementsByClassName('ratings'); // we access all our radio buttons elements by class name     
    var radios="";

    var i;
    for(i=0;i&lt;ratings.length;i++){
        ratings[i].onclick=function(){
            var result = 0;
            radios = document.querySelectorAll("input[class=ratings]:checked");
            for(j=0;j&lt;radios.length;j++){

            document.getElementById('overall-average-rating').innerHTML = result; // this row displays your total rating
