下拉列表值更改后的MVC3填充数据

Question

我的表格包含一些用于填充数据的文本。 我想在下拉列表更改后在文本框中填充数据。

MyView.chstml

@model BloodBank.Models.NewCamp

@{
  ViewBag.Title = "New Camp";
  Layout = "~/Views/Shared/_Layout - Menu.cshtml";
}

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

<script type="text/javascript">
$(function () {
    $("select#OrganisationID").change(function (evt) {

        if ($("select#OrganisationID").val() != "0") {

            $.ajax({
                url: "GetOrganizationInfo?orgID=" + $("select#OrganisationID").val(),
                type: 'POST',
                data: { OS: $("select#OrganisationID").val() },
                success: function (response) {
                    $("select#OrganisationID").replaceWith(response)
                },
                error: function (xhr) {
                    alert("Something went wrong, please try again");
                }
            });
        }
    });
});
</script>

我的行动

    [Authorize]

        {
            var model = (new UserManager()).GetCampPersonOrganisationDetailsByOrganisationID(orgID);
            Models.NewCamp newcampModel = new Models.NewCamp();

            if (model.Count > 0)
            {
                newcampModel.CampID = model[0].CampID;

                newcampModel.Phone = model[0].Phone;

                var organisations = this.GetOrganisations(model[0].BloodBankID);
                if (organisations != null)
                    ViewBag.OrganisationList = new SelectList(organisations, "OrganisationID", "NameCity");
            }

                return View("NewCamp", newcampModel);
        }
        else
            return View();
    }

我无法在表格中填写数据。 我不明白为什么我无法填充数据。 脚本或代码是否有变化？ 在下拉列表值更改后，是否有任何示例来填充数据？

---------更新------------

我曾在一个示例项目中尝试过类似的事情。 在这里，我可以获取值并显示在文本框中，但是每次从下拉菜单中选择操作系统时 ，都会在同一视图上添加一个视图 ，如下面的屏幕截图所示。

Answer 1

您发布的代码中唯一的缺陷可能是缺少；

success: function (response) {
    $("select#OrganisationID").replaceWith(response);
},

Answer 2

大家好，我已经解决了我的问题。 无需创建任何javascript 。 我没有使用javascript就解决了这个问题。

@Html.DropDownListFor(m => m.OrganisationID, (SelectList)ViewBag.OrganisationList, new { onchange = "document.location.href = 'NewCamp?orgID=' + this.options[this.selectedIndex].value;" })
