@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
}
