(mvc 3 + razor)应用程序中的问题 [英] Problem in (mvc 3 + razor ) application

问题描述

我的应用程序是在mvc 3 + razor中开发的，我有两页用于添加细节和编辑细节，并且在两页上都有一个名为Estimation的按钮，当我单击该按钮时，我会打开一个Estimation表单的模型jquery弹出窗口. > 当我选择年份时，估算页面的年份会下降，我会通过以下脚本填充所有费率.

My application developed in mvc 3 + razor , I have two page add detail and edit detail , and a button named Estimation on both page , When i click on the button i open a model jquery popup of Estimation form.
Estimation page having a dropdown of year''s when i select year i populate all rates by following script.

<script type ="text/javascript">

    $(function () {
        $('#RatePeriodid').change(function () {
            var selectedValue = $(this).val();
            $.ajax({
                type: "POST",
                url: '../WebServices/AddSOP.asmx/PopulateEstimationRates',
                data: "{Period_id:'" + selectedValue + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                async: false,
                success: function (msg) {
                   
                    var data = msg.d;
                    $('#Standerd_Weekday_Rate').val(data.Standerd_Weekday_Rate);
                     .................................
		     and so on 
                   
                },
                error: function (msg) {
                    alert("Error");


                }
            });

        });
    });
     
</script> 

我的问题是，当我从添加详细信息页面打开弹出窗口时，一切正常，但是当我从编辑详细信息页面打开弹出窗口，并从下拉列表中选择一年时，我的ajex脚本给出了错误消息.而且我的Web服务(../WebServices/AddSOP.asmx/PopulateEstimationRates)没有调用.
我的代码有什么问题?

My problem is when i open popup from add detail page all things are working fine , but when i open popup from edit detail page , and select an year from dropdown my ajex script giving error message. And my web service (../WebServices/AddSOP.asmx/PopulateEstimationRates) not calling .
What is the wrong with my code ?
