Question

我想多次将值传递给js函数，但是在调用之后，js函数将使用旧参数执行，然后再次使用新值执行我有html：

<a onclick="deleteConfirm(1,'abc')" href="#" class="badge badge-danger">Delete</a>
<a onclick="deleteConfirm(2,'def')" href="#" class="badge badge-danger">Delete</a>

这是JavaScript：

<script>
function deleteConfirm(id, title) {
        var delmodal = $('#deleteModal');
        delmodal.find('.modal-body').text(title);
        delmodal.modal('show');
        $('#deleteBtn').click(function () {
            delmodal.modal('hide');
            $.ajax({
            type: "POST",
            url: '@Url.Action("DeleteConfirmed", "Admin")',
            contentType: "application/json; charset=utf-8",
            data: JSON.stringify({ id: id }),
            dataType: "json",
                success: function (recData) {
                    var notify = $.notify('<strong>Thành công</strong><br/>' + recData.Message + '<br />', {
                        type: 'pastel-info',
                        allow_dismiss: false,
                    });
                },
                error: function () {
                    var notify = $.notify('<strong>Lỗi</strong><br/>Không xóa được<br />', {
                        type: 'pastel-warning',
                        allow_dismiss: false,
                    });
                }
        });
        });
    }
</script>

第一次单击徽章，值为1，“ abc”，但是第二次单击第二个链接，该值仍为1，“ abc”，此后，它将再次调用新的值2，“ def'。

Answer 1

您可能已经用相同的文件名在浏览器中缓存了JS文件。您可以尝试ctrl + f5重新加载，忽略缓存的内容。

Answer 2

您可以像这样向脚本源链接添加版本

$(".checkbox-menu").on("change", "input[type='checkbox']", function() { // this one to select multiple options as check box
  $(this).closest("li").toggleClass("active", this.checked);
  var sList = "";
  $('input[type=checkbox]').each(function() {
    if (this.checked) {
      sList += $(this).val() + ","
    }
  });

  $("#To").val(sList.slice(0, -1));
});

$(document).on('click', '.allow-focus', function(e) {
  e.stopPropagation();
});

最后，我意识到$（'＃deleteBtn'）。onclick将EventListener添加到元素中。

每次单击#deleteBtn时都会调用它，因此将多个事件侦听器附加到deleteBtn。这就是为什么我的ajax被多次调用的原因。

解决方案（只需将事件移出函数）：

<script>
function deleteConfirm(id, title) {
        var delmodal = $('#deleteModal');
        delmodal.find('.modal-body').text(title);
        delmodal.modal('show');
    }
$('#deleteBtn').click(function () {
        delmodal.modal('hide');
        $.ajax({
        type: "POST",
        url: '@Url.Action("DeleteConfirmed", "Admin")',
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify({ id: id }),
        dataType: "json",
            success: function (recData) {
                var notify = $.notify('<strong>Thành công</strong><br/>' + recData.Message + '<br />', {
                    type: 'pastel-info',
                    allow_dismiss: false,
                });
            },
            error: function () {
                var notify = $.notify('<strong>Lỗi</strong><br/>Không xóa được<br />', {
                    type: 'pastel-warning',
                    allow_dismiss: false,
                });
            }
    });
    });
</script>
