Question

我具有POST功能，我需要将JS的值从JS发送到Controller。字符串和整数值没有问题，但在服务器端没有达到double值，但是当我在本地尝试时，它正在工作。为什么会这样呢？

这是我的JS和控制器代码

var cmbvdf = $('#cmbvolDec').data('kendoComboBox');
var cmbvdfval = cmbvdf.value();
var cmbadf = $('#cmbamtDec').data('kendoComboBox');
var cmbadfval = cmbadf.value();
var cmbCur = $('#cmbCurrency').data('kendoComboBox');
var cmbcurrency = cmbCur.value();
var cmtheme = $('#cbmTheme').data('kendoComboBox');
var cmbvaltheme = cmtheme.value();
var cmblang = $('#cmbLanguage').data('kendoComboBox');
var cmbvallang = cmblang.value();
var custname = $("#txtCustName").val();
var websitetitle = $("#txtWebName").val();
var zoom = $("#txtZoom").val();


var lat1 = $("#txtLat1").val();
var lon1 = $("#txtLon1").val();
        var url = '../Setting/SaveRecords';
        $.ajax({
            type: "POST",
            url: url,
            data:JSON.stringify({ 'volumeDecimalFactor': cmbvdfval, 'amountDecimalFactor': cmbadfval, 'currency': cmbcurrency, 'theme': cmbvaltheme, 'language': cmbvallang, 'customerName': custname, 'lat1': lat1, 'lon1': lon1, 'web': websitetitle, 'zoom': zoom }),
            contentType: 'application/json, charset=utf-8',
            traditional: true,
            success: function (data) {
                //do something
            }
        });

这是我的C＃控制器

    public ActionResult SaveRecords(string volumeDecimalFactor, string amountDecimalFactor, string currency, string theme, string language, string customerName, double? lat1, double? lon1, string web, double? zoom)
    {
         //when i'm on my local machine i can get double values without problem.
         //when i published on server i cannot get values and return to me null!
    }

这是从Google Chrome网络标签页请求有效载荷

amountDecimalFactor: "2"
currency: "4"
customerName: "Fuel Card System"
language: "1"
lat1: "41.071789"
lon1: "28.980325"
theme: "4"
volumeDecimalFactor: "2"
web: "WebProject"
zoom: "5.2

请注意，我的本地PC和服务器在不同的国家/地区。

为避免这种情况，请始终在一个字符串中生成JSON并将其发送到Controller。就您而言，您可以执行以下操作：

<script type="text/javascript">
var cmbvdf = $('#cmbvolDec').data('kendoComboBox');
var cmbvdfval = cmbvdf.value();
var cmbadf = $('#cmbamtDec').data('kendoComboBox');
var cmbadfval = cmbadf.value();
var cmbCur = $('#cmbCurrency').data('kendoComboBox');
var cmbcurrency = cmbCur.value();
var cmtheme = $('#cbmTheme').data('kendoComboBox');
var cmbvaltheme = cmtheme.value();
var cmblang = $('#cmbLanguage').data('kendoComboBox');
var cmbvallang = cmblang.value();
var custname = $("#txtCustName").val();
var websitetitle = $("#txtWebName").val();
var zoom = $("#txtZoom").val();


var lat1 = $("#txtLat1").val();
var lon1 = $("#txtLon1").val();

  var json = {
              cmbvdfval : cmbvdfval,
              cmbadfval : cmbadfval,
              cmbcurrency : cmbcurrency ,
              cmbvaltheme : cmbvaltheme ,
              cmbvallang : cmbvallang ,
              custname : custname ,
              websitetitle : websitetitle  ,
              zoom : zoom ,
              lat1 : lat1 ,
              lon1 : lon1 
             };

    $.ajax({
        url: '@Url.Action("SaveRecords", "Setting")',
        type: 'post',
        dataType: "json",
        data: { "json": JSON.stringify(json)},
        success: function (result) {
             //do something
        },
        error: function (error) {
             console.log(error)
        }
      });

</script>

您可以像这样获得Controller中的值：

using System.Web.Script.Serialization;

[HttpPost]
public ActionResult SaveRecords(string json)
{

        var serializer = new JavaScriptSerializer();
        dynamic jsondata = serializer.Deserialize(json, typeof(object));

        //Get your variables here from AJAX call
        var zoom = jsondata["zoom"];
        var lat1 =jsondata["lat1"];

        //Do something with your variables here    

    return Json("Success");
}

MVC控制器无法从Ajax POST请求获取双精度值
