Question

我正在使用ASP.NET MVC4和Entity Framework开发一个Intranet Web应用程序。我有一个视图，它列举了我在数据库中的所有“人”，我可以编辑或删除它们。我正在尝试使用模态表单来确认删除操作（以便使用我的操作“删除”）。但是，为了做到这一点，我必须检索我想要删除的人的ID。

阅读了示例和文档后，我无法找到正确的方法来解除我想要删除的人的ID，以便将其用于我的行动。

我的删除操作：

public ActionResult Delete(long id)
    {
        Person person = db.Persons.Single(p => p.Id_Person == id);
        if (person == null)
        {
            return HttpNotFound();
        }

        db.Persons.DeleteObject(person);
        db.SaveChanges();

        return RedirectToAction("Index");
    }

我的观点（和模态）：

    @model IEnumerable<BuSIMaterial.Models.Person>

@{
    ViewBag.Title = "Index";
}

@using PagedList.Mvc;
@using PagedList;

<link href="/Content/PagedList.css" rel="stylesheet" type="text/css" />


<h2>Index</h2>

<br />

<div class="group">
    <div class ="btn-group">
        <input type="button" value="New person" class="btn" onclick="location.href='@Url.Action("Create")';return false;"/>
        <input type="button" value="Download report" class="btn" onclick="location.href='@Url.Action("PersonReport")';return false;"/>
    </div>
</div>


@using (Html.BeginForm("SelectedPersonDetails", "Person"))
{  
    <form class="form-search">
        <label for="person">Search an employee : </label>
        <input type="text" id="tbPerson" name="tbPerson" class="input-medium search-query">
        <button type="submit" class="btn">Search</button>
    </form>
}

@section Scripts
{
    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/jqueryui")
    @Styles.Render("~/Content/themes/base/css")

    <script type="text/javascript" language="javascript">
        $(document).ready(function () {
            $('#tbPerson').autocomplete({
                source: '@Url.Action("AutoComplete")'
            });
        })

        $('#myModal').modal(options)

    </script>
}

我可以通过data-id ="@item.Id_Person"来获取ID，但我不知道如何使用它来最终调用我的动作。伙计们好吗？

我不确定您是否想使用jQuery之类的东西执行Ajax删除 - 或者如果您只想使用ASP.NET MVC。

如果您想使用Javascript，您将从data-id中提取Id，并使用$.ajax向控制器发送删除请求。

如果你想使用MVC和Ajax，我想你可能需要一个Ajax.ActionLink

如果您只想删除RedirectToAction，那么只需要正常的HTML.ActionLink

MVC 4将数据传递给Bootstrap Modal表单
