我有一个代码，我试图调用aweetalert，注意它使用的是sweetalert，而不是sweetAlert2。
这里是代码
JS代码

function showMessage() {
    swal({
        title: "",
        html: 'Update <b>data.</b>',
        type: "warning",
        showCancelButton: true,
        confirmButtonColor: "##EF5350",
        confirmButtonText: "Yes, Proceed",
        cancelButtonText: "Cancel",
        reverseButtons: true
    },function(isConfirmed) {
        alert(isConfirmed)
        if (isConfirmed) {
            alert($(".openStandings").attr('data-href'));
            $.ajax({
                type: "POST",
                url: $(".openStandings").attr('data-href'),
                success: function(data) {
                alert(data);
                if (data.toLowerCase().indexOf("error") >= 0) {
                    swal({
                        title: "Oops",
                        text: data,
                        type: "error",
                        showCancelButton: false,
                        confirmButtonColor: "##EF5350",
                        confirmButtonText: "OK",
                        closeOnConfirm: true
                    });
                } else {
                    swal({
                        title: "Great",
                        text: data,
                        type: "success",
                        showCancelButton: false,
                        confirmButtonColor: "##EF5350",
                        confirmButtonText: "OK",
                        closeOnConfirm: true
                    });
                }
            }
            })
        }
    })
}

对象首先是swal工作，但当它进入回调时，什么也没有发生
