Answer 1

var rates = document.getElementById('rates').value;

cannot get values of a radio button like that instead use

rate_value = document.getElementById('r1').value;

Answer 2

The one worked for me is given below from api.jquery.com.

HTML

<input type="radio" name="option" value="o1">option1</input>
<input type="radio" name="option" value="o2">option2</input>

JavaScript

var selectedOption = $("input:radio[name=option]:checked").val()

The variable selectedOption will contain the value of the selected radio button (i.e) o1 or o2

Answer 3

HTML CODE:

<input type="radio" name="rdoName" value="YES"/> <input type="radio" name="rdoName" value="NO"/>

JQUERY CODE:

var value= $("input:radio[name=rdoName]:checked").val();

$("#btnSubmit").click(function(){
var value=$("input:radio[name=rdoName]:checked").val();
console.log(value);
alert(value);
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="rdoName" value="YES"/> YES
<input type="radio" name="rdoName" value="NO"/> NO
<br/>
<input type="button"id="btnSubmit"value="Which one Selected"/>

You will get

value="YES" //if checked Radio Button with the value "YES"
value="NO" //if checked Radio Button with the value "NO"

   var rates=document.getElementsByName("rate");
            for (i = 0; i < rates.length; i++) {
            if (rates[i].checked) {
              console.log(rates[i].value);
              rate=rates[i].value;
              document.getElementById("rate").innerHTML = rate;
              alert(rate);
              
            }
          }

        <div id="rates">
          <input type="radio" id="r1" name="rate" value="Fixed Rate"> Fixed Rate
          <input type="radio" id="r2" name="rate" value="Variable Rate"> Variable Rate
          <input type="radio" id="r3" name="rate" value="Multi Rate" checked="checked"> Multi Rate  
        </div>
        </br>
        <div id='rate'>
        </div>

You can also loop through the buttons with a forEach-loop on the elements

    var elements = document.getElementsByName('radioButton');
    var checkedButton;
    console.log(elements);
    elements.forEach(e => {
        if (e.checked) {
            //if radio button is checked, set sort style
            checkedButton = e.value;
        }
    });
