SweetAlert confirm with Ajax request

Question

I'm new at Javascript - coding it actually for the first time. I'm trying to do a button with delete confirmation with SweetAlert. Nothing happens when I press the button with onclick="confirmDelete()". This code may be just crab, but here it is:

<script type="text/javascript">
    function confirmDelete() {
        swal({
            title: "Are you sure?",
            text: "You will not be able to recover this imaginary file!",
            type: "warning",
            showCancelButton: true,
            confirmButtonColor: "#DD6B55",
            confirmButtonText: "Yes, delete it!",
            closeOnConfirm: false
        )},
            $.ajax({
                url: "scriptDelete.php",
                type: "POST",
                data: {id: 5},
                dataType: "html",
                success: function () {
                    swal("Done!","It was succesfully deleted!","success");
                }
            });
    }
</script>

<a href="#" onclick="confirmDelete()">Delete</a>

Can I add any alert if deleting fails?

Answer 1

If I understand your question correctly, you are asking how to handle error condition in ajax request. Ajax settings has an error attribute and it can be used like this

$.ajax({
  .... other settings you already have
  error: function (xhr, ajaxOptions, thrownError) {
    swal("Error deleting!", "Please try again", "error");
  }
});

Also, you are invoking swal in a wrong way. Swal has a callback like this

swal({settings}, function(isConfirm){});

Overall code would look something like this

function confirmDelete() {
    swal({
        title: "Are you sure?",
        text: "You will not be able to recover this imaginary file!",
        type: "warning",
        showCancelButton: true,
        confirmButtonColor: "#DD6B55",
        confirmButtonText: "Yes, delete it!",
        closeOnConfirm: false
    }, function (isConfirm) {
        if (!isConfirm) return;
        $.ajax({
            url: "scriptDelete.php",
            type: "POST",
            data: {
                id: 5
            },
            dataType: "html",
            success: function () {
                swal("Done!", "It was succesfully deleted!", "success");
            },
            error: function (xhr, ajaxOptions, thrownError) {
                swal("Error deleting!", "Please try again", "error");
            }
        });
    });
}
