alert message for radio button

I am trying to generate a alert message .When radio button does not select. Here is my code.

<form method=post name="spendform" id="spendform">
<input name="price" type="radio" class="invest-coin-check"  id="pricemethod" >
<button type=submit class="btn btn-lg btn-p-h btn-bw" id="mypayment">Make Investmen

t Here is java-script code

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
    $(document).ready(function () {
        $('#mypayment').click(function () {
            if ($('#pricemethod').val() == '') {
                alert('Please Select Payment options');
                return false;
            }
        });
    });
</script>

Here:

$('#mypayment').click(function(){
   if($('#pricemethod').is(':checked')){
      alert('Please Select Payment options');
   }else{
      $('#spendform').submit();
   }
});

.is(':checked') by MH2K9

Use .is(':checked') instead of .val() . .is(':checked') returns true if it is checked, otherwise it returns false .

 $(document).ready(function() { $('#mypayment').click(function(){ if(!$('#pricemethod').is(':checked')){ alert('Please Select Payment options'); return false; } }); }); 
 <script src="https://code.jquery.com/jquery-1.12.4.min.js"></script> <form method=post name="spendform" id="spendform"> <input name="price" type="radio" class="invest-coin-check" id="pricemethod" > <button type=submit class="btn btn-lg btn-ph btn-bw" id="mypayment">Make Investmen</button> </form>
