如何保存c＃asp.net中的特殊字符

Question

我有这JS代码以保存用户输入的数据。所有数据在var JsonData = JSON.stringify(data);。我输入了一个特殊字符Task (& sign)[Task Value is (A & B)]。但在我的控制器中，它在&标志前削减了数据。

$('#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" 
    }); 
}); 

这里是我的控制器代码，我把一个断点，并调试它为什么在这个代码ovt = jss.Deserialize<OvertimeRequest>((string)overtimeRequest);在它到达后直接到catch。正如我上面提到的那样，它会在&之前削减数据。

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."; 
     } 
    }

，因为你正在做一个GET请求，你正在失去的数据。当您进行GET调用时，数据将作为查询字符串发送，并且&在查询字符串中时具有特殊含义。它是不同querystring项目的分隔符。

你应该做的是，进行POST调用服务器。也不需要像模型绑定器那样明确地执行反序列化。只需创建一个C＃POCO类，它代表您正在发送的数据的结构，并将其用作您的操作方法参数。

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 
    } 
}); 

现在请确保您使用我们作为参数

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

我弄明白感谢所有谁看到我的帖子创建的视图模式。

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