为什么Request [“parameter”]在webmethod中为null?

标签: asp.net request jtable

我正在使用asp.net。使用jTable,如果我将listaction放到某个页面(并在pageload中添加代码),它工作正常。如果我将webmethod添加到同一页面的代码后面的listaction代码中,那么获取

  

HttpContext.Current.Request [“frmdate”] = null

HTML代码

 <div id="dSaleBillContainer" style="padding-top: 115px;"></div>

jTable代码

 $('#dSaleBillContainer').jtable({
                title: 'Sale Bills (User : <label id="user"></label>)',
                paging: true,
                pageSize: 10,
                pageSizes: [10, 25, 50, 75],
                sorting: true,
                defaultSorting: 'S01F01 DESC',
                selecting: true, //Enable selecting
                multiselect: true, //Allow multiple selecting
                selectingCheckboxes: true, //Show checkboxes on first column
                selectOnRowClick: false,
                openChildAsAccordion: true,
                actions: {
                    listAction: 'dSaleBills.aspx/List'
                    //listAction: 'GetSalesBill.aspx?Mode=List' - this way working perfect with same code which is calling another page and issue is with same page code behind webmethod

                },
               .......
        });

我如何填充数据,实际上这种方法是否正常工作

 $('#btnLoad').click(function (e) {
            debugger;
            e.preventDefault();
            $('#dSaleBillContainer').jtable('load', {
                user: $('#ddlsbUsers').val(),
                frmdate: $('#<%=txtFrmDate.ClientID %>').val(),
                todate: $('#<%=txtToDate.ClientID %>').val(),
                route: $('#ddlRoute').val() == "0" ? $('#ddlRoute').val() : $('#ddlRoute option:selected').text(),
                searchText: $('#<%= txtSearchText.ClientID %>').val()
            });
            var ddlsbUsers = $("[id*=ddlsbUsers]");
            $("#user").html(ddlsbUsers.find("option:selected").text());
        });

        //Load all records when page is first shown
        $('#btnLoad').click();

webmethod代码

 [System.Web.Services.WebMethod]
        public static String List()
        {
            string Result;
            string a = HttpContext.Current.Request["frmdate"];
            string frmdate = HttpContext.Current.Request["frmdate"].ToString();
        }

这是什么解决方案?

有没有更好的解决方案呢?答案对我很有帮助.........
