jquery ajax 为什么没执行......................................................新手在线求解

$(".titleBack").each(function () {

                $(this).bind("click", function () {

                    

                    var titleId = $(this).attr('id');

                    $.ajax({

                        type: "post",

                        url: "../CallingPage/titleBackColorCalling.aspx?iTitle='" + titleId + "'",

                        data: null,

                        datatype: "json"

                    });

                });

            });

            



            $(".format").each(function () {

                $(this).bind("click", function () {

                    

                    var formatId = $(this).attr('id');

                    $.ajax({

                        type: "post",

                        url: "../CallingPage/reviseFormatCalling.aspx?formatName='" + formatId + "'",

                        data: null,

                        datatype: "json"

                    });

                });

            });

titleBack 和 format 是<a>的class属性
为什么 format 执行了
titleBack 没有执行titleBackColorCalling.aspx页面


------最佳解决方案--------------------
如果路径都没问题的话,请检查 titleBackColorCalling 名称和aspx.cs的命名
