Question

Answer 1

success and error callbacks can be used in that way. For done and fail, you need to do :

$.ajax({
    type: "POST", 
    url: postUrl,
    data: dataToPost,
}).done(function() {
    alert("Success.");
}).fail(function() {
    alert("Sorry. Server unavailable. ");
});

Or :

$.ajax({
    type: "POST", 
    url: postUrl,
    data: dataToPost,
    success: function() {
            //code here
    }
});
