Question

我在下面有这个JS代码来保存用户输入的数据。所有数据均见var JsonData = JSON.stringify(data);。我在Task (& sign) [Task Value is (A & B)]中输入了一个特殊字符。但是在我的控制器中，它会在&符号之前剪切数据。

$('#btn_SubmitOT').live('click', function () {
    if (lastSel != -1) {
        $('#' + lastSel + '_isValidated').val(true);
        //            $('#' + lastSel + '_RequestedBy').val();
        var datefiled = $('#ot_dateFiled').val().
        $('#' + lastSel + '_OTDateApplied').val(datefiled);
        jQuery('#grdOTApplication').saveRow(lastSel, false, 'clientArray');
    }
    var task = $("#task_ot").val();
    //var data = $("#grdOTApplication").jqGrid('getRowData');
    var data = {
        DateFiled: $("#ot_dateFiled").val(),
        DateofOvertime: $("#ot_dateOfOT").val(),
        EmployeeId: $("#empApplicants").val(),
        In1: $("#from_sup").val() + $("#from_AM_PM").val(),
        Out1: $("#to_sup").val() + $("#to_AM_PM").val(),
        EstimatedHours: $("#estimateHrsWrk_ot").val(),
        SpecificTask: task,
        ApprovedBy: $("#approveofficial").val() != null ? $("#approveofficial").val() : 0,
        RecommendedBy: $("#recommenders").val() != null ? $("#recommenders").val() : 0,
        SupervisedBy: $("#immediatesupervisor").val() != null ? $("#immediatesupervisor").val() : 0,
        IsCOC: $('#cmbCO').val() == 1 ? true : false
    }


    var JsonData = JSON.stringify(data);

    var urlPA = '../Request/saveOvertimeRequest?overtimeRequest=' + JsonData + '&_role = 3;

    $.ajax({
        type: "GET",
        url: urlPA,
        success: function (response) {
            alert(response);
            $("#grdOTApplication").trigger("reloadGrid", [{
                current: true
            }]);
            $("#grdOTHistory").trigger("reloadGrid", [{
                current: true
            }]);
            $("#ot_dateOfOT").val("");
            $("#from_sup").val("__:__");
            $("#to_sup").val("__:__");
            $("#estimateHrsWrk_ot").val("");
            $("#task_ot").val("");
        },
        error: function (response) {
            alert("Error");
        },
        datatype: "text"
    });
});

这是我的控制器代码我放了一个断点并调试它为什么在它到达此代码ovt = jss.Deserialize<OvertimeRequest>((string)overtimeRequest);后它指向catch。正如我在上面提到的那样，它会在&符号之前剪切数据。

public String saveOvertimeRequest(String overtimeRequest, int _role)
    {
        Nullable<DateTime> MyNullableDate = null;
        try
        {
            Int32 requestedBy = Convert.ToInt32(HttpContext.Current.Session["PersonId"]);
            Int32 empId = Convert.ToInt32(HttpContext.Current.Session["EmpId"]);

            OvertimeRequest ovt = new OvertimeRequest();
            JavaScriptSerializer jss = new JavaScriptSerializer();
            ovt = jss.Deserialize<OvertimeRequest>((string)overtimeRequest);
            ovt.IsFromESS = true;
            ovt.RequestedBy = requestedBy;
            if (_role == 3 || ((ovt.SupervisedBy == 0 || ovt.SupervisedBy == null) && ovt.RecommendedBy > 0 && ovt.ApprovedBy > 0))
            {
                ovt.SupervisedBy = null;
                ovt.DateSupervised = DateTime.Now;

            }
            if (_role == 4 || ((ovt.SupervisedBy == 0 || ovt.SupervisedBy == null) && (ovt.RecommendedBy == 0 || ovt.RecommendedBy == null) && ovt.ApprovedBy > 0))
            {
                ovt.SupervisedBy = null;
                ovt.DateSupervised = DateTime.Now;
                ovt.RecommendedBy = null;
                ovt.DateRecommend = DateTime.Now;

            }
            if (_role == 5 || ((ovt.SupervisedBy == 0 || ovt.SupervisedBy == null) && (ovt.RecommendedBy == 0 || ovt.RecommendedBy == null) && (ovt.ApprovedBy == 0 || ovt.ApprovedBy == null)))
            {
                ovt.SupervisedBy = null;
                ovt.DateSupervised = DateTime.Now;
                ovt.RecommendedBy = null;
                ovt.DateRecommend = DateTime.Now;
                ovt.ApprovedBy = null;
                ovt.DateApproved = DateTime.Now;
                ovt.IsPosted = true;
                ovt.DatePosted = DateTime.Now;
            }
            try
            {
                db.AddToOvertimeRequests(ovt);
                db.SaveChanges();
            }
            catch (Exception)
            {
                throw;
            }
          }
        catch (Exception e)
        {
            return "An error has occured while sending your request.";
        }
    }

您正在丢失数据，因为您正在执行GET请求。当你进行GET调用时，数据将作为查询字符串发送，&在查询字符串中具有特殊含义。它是不同查询项目的分隔符。

您应该做的是，对服务器进行POST调用。此外，没有必要明确地进行反序列化，因为模型绑定器会为您执行此操作。只需创建一个C＃POCO类，它表示您要发送的数据结构，并将其用作操作方法参数。

public class OverTimeViewModel
{
  public DateTime DateFiled { set;get;}
  public DateTime DateofOvertime { set;get;}
  public int EstimatedHours { set;get;}
  //Add other properties here
}

并在javascript代码中，使用POST作为ajax方法。

var viewModel = {
                  DateFiled: '12/12/2012'
                  EstimatedHours : 10
                } ;
// values hard coded for demo. Replace with real values
$.ajax({
    type: "POST",
    url: urlPA,
    data : viewModel 
    success: function (response) {
      //do something with the response
    }
});

现在确保使用我们创建的视图模型作为参数

public ActionResult SaveOvertimeRequest(OverTimeViewModel model)
{
  //check model.DateField etc and use 
}

感谢所有查看我帖子的人。

我使用此代码var task =escape($("#task_ot").val());
