Question

我尝试从Jquery中的控制器操作中读取Kendo Dropdownlist。代码是

$("#CountryName").kendoDropDownList({
    dataTextField: "Description",
    dataValueField: "Id",
    dataSource: {
        transport: {
            read: {
                dataType: "jsonp",
                url: "Shared/CountryAjax"
            }
        }
    }
});

[HttpPost]
public ActionResult CountryAjax(string countryId)
{
    var countries = this._decodeBL.GetAllCountriesList();

    return new JsonResult
    {
        Data = new SelectList(countries, "Id", "Description", "Canada")
    };
}

但它永远不会执行CountryAjax。我需要帮助。感谢。

Answer 1

我发现你的代码中有两个错误。首先，您应该在服务器方法中使用[HttpGet]注释。其次，您不应该在服务器方法中接收countryId。

请参阅下面的固定代码。

$("#CountryName").kendoDropDownList({
    dataTextField: "Description",
    dataValueField: "Id",
    dataSource: {
        transport: {
            read: {
                dataType: "jsonp",
                url: "Shared/CountryAjax"
            }
        }
    }
});


[HttpGet]
public ActionResult CountryAjax()
{
    var countries = this._decodeBL.GetAllCountriesList();

    return new JsonResult
    {
        Data = new SelectList(countries, "Id", "Description", "Canada")
    };
}

 $("#selectYears").kendoDropDownList({
        dataTextField: "Text",
        dataValueField: "Value",
        //dataSource: data2,
        dataSource: {
            transport: {
                read: {
                    type: "GET",
                    dataType: "json",
                    url: '@Url.Action("GetYears", "NewHome")'
                }
            }
        },
        index: 0,
        change: onChange
    });

   return new JsonResult
        {
            Data = new SelectList(years, "newHomeIndexid", "selectedYear"),
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
