从 ajax jQuery 调用传递空的 mvc 模型

>我有一个返回地址输入组的部分视图，一个是加拿大的，一个是美国人。我的部分使用模型来编辑当前数据，但它也处理添加新数据。因此，模型应为空。到目前为止，我无法加载部分。

jQuery中的Ajax调用：

$.ajax({
                    url: 'Views/AddressByCountry',
                    type: 'GET',
                    async: false,
                    data:  { model: null, country: country },
                    contentType: 'application/json; charset=utf-8',
                    success: function(page) {
                        alert(page);
                        $('.addressarea').html(page);
                    }
                });

调用部分的主视图：

@if (@Model == null) //addnew
                                {
                                    <div class="col-md-12">
                                        <div class="row">
                                            <div class="col-md-5 ">
                                                @Html.Partial("AddressByCountry", Model)
                                            </div>
                                            <div class="col-md-7 addressarea">
                                                <input id="CountryChkBox" type="checkbox" name="@country">
                                                <label id="countryLabel" class="no-colon">@((country.ToString()) == "US" ? "Canadian Address" : "USA Address")</label>
                                            </div>
                                        </div>
                                    </div>
                                }

部分视图：

@model MyModel.Contact
@{
     Layout = null;
    var country = TempData["country"];
}
@if (country.ToString() == "US")
{
 <div class="col-md-12">
    <div class="form-inline">
        <div class="form-group">
            @Html.Label("Address", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Address", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">
            @Html.Label("Address2", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Address2", null, new { @class = " form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
    </div>
</div>
<div class="col-md-12">
    <div class="form-inline">
        <div class="form-group">
            @Html.Label("City", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("City", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">
            @Html.Label("State", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("State", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">
            @Html.Label("Zip", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Zip", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
    </div>
</div>
}
else
{
 <div class="col-md-12">
    <div class="form-inline">
        <div class="form-group">
            @Html.Label("Address", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Address", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">
            @Html.Label("Address2", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Address2", null, new { @class = " form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
    </div>
</div>
<div class="col-md-12">
    <div class="form-inline">
        <div class="form-group">
            @Html.Label("City", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("City", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">
            @Html.Label("Province", null, new { @class = "control-label no_wrap" })
            @Html.TextBox("Province", null, new { @class = "form-control ", @onKeyup = "enableButton()", tabindex = "4" })
        </div>
        <div class="form-group">

        </div>
    </div>
</div>
}

控制器：

public ActionResult AddressByCountry(MyModel.Contact model, string country = "US")
    {
        TempData["country"] = country;
        return PartialView("AddressByCountry", model);
    }

联系人类：

 public class Contact 
{
    public bool IsActive { get; set; }
    public int Id { get; set; }
    public string FullName
    {
        get
        {
            if (FirstName != null && LastName != null)
            {
                return LastName + ", " + FirstName;
            }
            else
                return string.Empty;
        }
    }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Address { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Province { get; set; }
    public string Zip { get; set; }
    public string Category { get; set; }
    public List<ContactList> Contacts { get; set; }
    }

从 ajax jQuery 调用传递空的 mvc 模型

尝试像这样调用您的部分视图

@Html.Partial("AddressByCountry", Model == null ? new Contact() : Model)

要在 ajax 调用中传递此模型， 

var getModelData = @Html.Raw(Json.Encode(Model));    
$.ajax({
                    url: 'Views/AddressByCountry',
                    type: 'GET',
                    async: false,
                    data:  { model: getModelData , country: country },
                    contentType: 'application/json; charset=utf-8',
                    success: function(page) {
                        alert(page);
                        $('.addressarea').html(page);
                    }
                });
