@akashmanujaya i have done small change to code, try this

function saveData() { var confirmed = document.getElementById('confirmed').checked ? 1 : 0; var id = document.getElementById('id').value; var Condition=$('input[name="Condition"]:checked').val(); //check this line var fd = new FormData(); fd.append('confirmed', confirmed); fd.append('id', id); fd.append('Condition',Condition); //uncomment this line }
