我有一个关于使用 ajax 将数据从视图发送到控制器的问题。
这是我的观点：

@model GDMfrontEnd.Models.DeliverableViewModel

@{
    ViewBag.Title = "Create";
}

<div class="row">
<div class="large-12 columns">
<h2>Uploaden!</h2>
@using (Html.BeginForm("Create", "Deliverable", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
        <p><img src="~/Content/images/step1.png" />Selecteer jouw afbeeldingen</p>
        <div class="editor-label">
            @Html.LabelFor(model => model.Thumbnail)
        </div>
        <div class="editor-field">
            @Html.TextBoxFor(model => model.Thumbnail, new { type = "file" })
            @Html.ValidationMessageFor(model => model.Thumbnail)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Image)
        </div>
        <div class="editor-field">
            @Html.TextBoxFor(model => model.Image, new { type = "file" })
            @Html.ValidationMessageFor(model => model.Image)
        </div>

            <div class="editor-label">
            @Html.LabelFor(model => model.VideoUrl)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.VideoUrl)
            @Html.ValidationMessageFor(model => model.VideoUrl)
        </div>

        <p><img src="~/Content/images/step2.png" />Informatie</p>


        <div class="editor-label">
            @Html.LabelFor(model => model.Title)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Title)
            @Html.ValidationMessageFor(model => model.Title)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.Projects)
        </div>
        <div class="editor-field">
             @Html.DropDownListFor(model => model.ProjectID, new SelectList(ViewBag.Projects, "project_id", "project_name", Model.ProjectID))
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Description)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Description)
            @Html.ValidationMessageFor(model => model.Description)
        </div>


        <div class="editor-label">
            @Html.LabelFor(model => model.TagName)
        </div>
        <div class="editor-field">
             <input type="text" id="tags" />
        </div>

        <p>
            <input id="submit" type="submit" value="Create" />
        </p>
}
</div>
</div>

@section Scripts {

                    source: function (request, response) {
                        // delegate back to autocomplete, but extract the last term
                        response($.ui.autocomplete.filter(
                            object.tags, extractLast(request.term)));
                    },
                    focus: function () {
                        // prevent value inserted on focus
                        return false;
                    },
                    select: function (event, ui) {
                        var terms = split(this.value);

                        // add placeholder to get the comma-and-space at the end
                        terms.push("");
                        this.value = terms.join(", ");

                        return false;

                $.ajax({

                    url: "/Deliverable/AddTags",
                    data: terms,
                    contentType: "application/json; charset=utf-8",

                        alert('success');
                    },
                    error: function () {
                        alert('failure');
                    }
                });
            });


    </script>
}

我有一个 html 表单，底部有一个文本框，您可以在其中向文本框添加标签。（标签在数据库中定义）

问题是 ajax 没有做任何事情。他甚至没有进入我的行动方法。

谁能帮我这个？我想将数组项发送到我的控制器中的操作方法。

编辑：

我的行动：

[HttpPost]
    public ActionResult AddTags(List<string> data)
    {
        return View();
    }

我只是在动作开始时有一个断点来检查它是否到达动作但没有结果..

您正在为您的操作设置 HTTPPost 属性，这意味着该操作将仅映射到发布请求。在您的 ajax 脚本中，您通过类型 Get 定义，这意味着将使用 get 请求触发 ajax 请求。

删除该属性或更改请求的类型
