@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
}
