SweetAlert用Ajax请求确认

Question

我是Javascript的新手 - 实际上是第一次编码.我正在尝试使用SweetAlert删除确认按钮.当我按下按钮时没有任何反应onclick="confirmDelete()".这段代码可能只是螃蟹,但这里是:

<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>

如果删除失败,我可以添加任何警报吗？

如果我正确理解你的问题,你就会问如何处理ajax请求中的错误条件.Ajax设置有一个错误属性,它可以像这样使用

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

此外,您正在以错误的方式调用swal.Swal有这样的回调

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

整体代码看起来像这样

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");
            }
        });
    });
}

试试这个代码。它对我来说很好用。

$('.delete-confirm').on('click', function() {
    var postID = $(this).val();
    console.log(postID);
    swal({
        title: "Are you sure?",
        text: "If you delete this post all associated comments also deleted permanently.",
        type: "warning",
        showCancelButton: true,
        closeOnConfirm: false,
        showLoaderOnConfirm: true,
        confirmButtonClass: "btn-danger",
        confirmButtonText: "Yes, delete it!",
    }, function() {
        setTimeout(function() {
            $.post("delete.php", {
                    id: postID
                },
                function(data, status) {
                    swal({
                            title: "Deleted!",
                            text: "Your post has been deleted.",
                            type: "success"
                        },
                        function() {
                            location.reload();
                        }
                    );
                }
            );

        }, 50);
    });
});
