How to get radio button selected value using javascript

See my sample here:

Markup

<input type="radio" value="1" name="choice">1</input>
<input type="radio" value="2" name="choice">2</input>
<input type="radio" value="3" name="choice">3</input>
<br/>
You selected: 
<label id="choiceLabel"></label>

JS

(function (){
    var radios = document.getElementsByName('choice');
    console.log(radios);
    for(var i = 0; i < radios.length; i++){
        radios[i].onclick = function(){
            document.getElementById('choiceLabel').innerText = this.value;
        }
    }
})();

I googled "get radio button value javascript" and quickly found this

javascript - How to get value of selected radio button? - Stack Overflow[^]

Please do basic research before asking a question, if that link doesn't help you there are many more if you google yourself.

var valueSelected=document.querySelector('input[name="my_input_radio_name"]:checked').value;

you could use Jquery to simplify your code

$('nameofradibutton).On('click', function() {

 // your algo
});

You can radio value with js

var myRadio = document.getElementsByName("your-radio-name").value;
//Console the value
console.log(myRadio)
