Question

我正在尝试通过Ajax将List发送给我的acton。此刻，我正在为我的行动获取数据，但恢复的数据是胡言乱语，例如evrything是NULL，有5个元素，而不是一个。我需要通过jquery收集数据，因为我想动态扩展这个列表。

我认为根本问题是我的JSON与我的行动期望的JSOn有所不同 - 但我是新手，并没有看到错误。发送给操作的JSON是：

    {
    "ideas": [
        {
            "name": "[0].ID",
            "value": "1"
        },
        {
            "name": "[0].Name.EnglishText",
            "value": "New Idea"
        },
        {
            "name": "[0].Name.GermanText",
            "value": "Neue Idee"
        },
        {
            "name": "[0].Description.EnglishText",
            "value": "1"
        },
        {
            "name": "[0].Description.GermanText",
            "value": "1"
        }
    ]
}

我尝试构建我的列表的JSOn版本，如下所示：实际上完全不同:(

"[{
    "ID":0,
    "Name":
    {
        "EnglishText":"English",
        "GermanText":"Ger"
    },
    "Description":
    {
        "EnglishText":null,
        "GermanText":null
    },
    "Project":null
}]"

让我解释一下：该网站如下：

 <div id="collapseIdeas" class="panel-collapse collapse">
            <div class="panel-body">
                @for (int i = 0; i < Model.Count(); i++)
                {
                    <div class="panel panel-default">
                        <div class="panel-heading">@Model[i].Name.GetText()</div>
                        <div class="panel-body">
                            @Html.HiddenFor(mbox => Model[i].ID)

                            <div class="form-group">
                                @Html.LabelFor(m => Model[i].Name, htmlAttributes: new { @class = "control-label col-md-2" })
                                <div class="col-md-10">
                                    @Html.EditorFor(model => Model[i].Name, new { htmlAttributes = new { @class = "form-control" } })
                                    @Html.ValidationMessageFor(model => Model[i].Name, "", new { @class = "text-danger" })
                                // warning: abbreviated, originally 5 inputs in this panel-body
                                </div>
                            </div>
                        </div>
                        <div class="panel-footer">
                            <button type="button" id="ButtonDeleteIdea" class="btn btn-danger" value="@Model[i].ID">@CreateRes.DeleteIdea</button>
                        </div>
                    </div>
                }
            </div>
            <div class="panel-footer">
                <button type="button" class="btn btn-primary ButtonAddIdea">@CreateRes.AddIdea</button>
            </div>

使用的Ajax调用：

$(function () {
    $(".ButtonAddIdea").click(function () {
        var data = testFct();
        alert(data);
        $.ajax(
            {
                type: "POST",
                url: window.AddAnotherIdea,
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
                data: data,
            }).done(function (html) {
                $("#IdeaList").replaceWith(html);
            });
    });
});

function testFct() {
    var list = $("#IdeaList :input")
    var test = list.serializeArray()
    things = JSON.stringify({ 'ideas': test });
    return things
}

接收方法：

[HttpPost]
public async Task<PartialViewResult> AddAnotherProjectIdea(List<ProjectIdea> ideas)
    {
    // gets called, and the List is not null - but the list appears to contain only
    // gibberish, with every value 0 or NULL. 
    //Also there are 5 elements, there should be only one
    }

Jquery Ajax到MVC会产生意想不到的结果
