创办公共调用 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>
