创建公共调用 jQuery Ajax 带返回值

     <script type="text/javascript">        /* 请求Ajax 带返回值，并弹出提示框提醒        --------------------------------------------------*/        function getAjax(url, parm, callBack) {            $.ajax({                type: 'post',                dataType: "text",                url: url,                data: parm,                cache: false,                async: false,                success: function (msg) {                    callBack(msg);                }            });        }           /*删除        /*url:        表示请求路径        --------------------------------------------------*/        function DeleteData(url, id) {            var parm = 'active=Del&id=' + id;            if (id == undefined || id == "") {                showAlertMsg('请选择要删除一行');            } else {                showConfirmMsg("此操作不可恢复，确定要删除吗？", function (r) {                    if (r) {                        getAjax(url, parm, function (rs) {                            if (parseInt(rs) > 0) {                                showOverAlertMsg("删除成功！", 2000, 4);                            } else if (parseInt(rs) == 0) {                                showOverAlertMsg("该数据被关联,无法删除！", 2000, 3);                            }                            else {                                showOverAlertMsg("删除失败！", 2000, 5);                            }                        });                    }                });            }        }        先看式如何调用      //删除      function DeleteOnclick() {            DeleteData('SysMenu_List.aspx', Menu_Id);        }    </script>
