Adding radio buttons

Adding radio buttons

I want to be able to have a yes or a no selection option for each question and then I will use c# to get that selected value. Not sure how to do modify jquery code to work with more radio buttons...Anyone guide me please? Thanks!

<label   class = "label_radio r_on"   for = "radio-01" > <input   name = "sample-radio"   id = "radio-01"   value = "1"   type = "radio" checked = ""   /> Yes. </label>
<label   class = "label_radio"   for = "radio-02" > <input   name = "sample-radio"   id = "radio-02"   value = "2"   type = "radio"   />  No. </label>
    <script>
       
function setupLabel() {
           
if ($('.label_radio input').length) {
                $
('.label_radio').each(function () {
                    $
(this).removeClass('r_on');
               
});
                $
('.label_radio input:checked').each(function () {
                    $
(this).parent('label').addClass('r_on');
               
});
           
};
       
};
        $
(document).ready(function () {
            $
('.label_check, .label_radio').click(function () {
                setupLabel
();
           
});
            setupLabel
();
       
});
   
</script>
