【问题描述】：
我有一个数据库，我想用填充符fill 填写-method。我希望从我的MVC-project 中的Index-view 调用这个method。我已经测试了method 每次运行index.cshtml 时都会运行它，它会填充table。唯一的问题是，如果我refreshindex-page，table 再次被完全相同的data 填充。这导致我得到了每件物品中的两个。
所以我得出的结论是，我想将我的filler()-method 绑定到索引页面上的一个按钮以填充table。那么我的问题是：
如何直接将方法绑定到我的project 中的按钮？
额外信息：
填充方法在其自己的名为 DBFiller.cs 的类中，当我将其设置为在索引启动时运行时，我在 actionresult 的 controller 中添加了 DBfiller.filler()。
代码：

itemDb.registerItem(item12);
userDb.setIn(user1);
userDb.setIn(user2);
userDb.setIn(user3);
}
}
}
我尝试将它添加到我的用户控制器的索引启动器中：
namespace Oblig1.Controllers
{
public class UserController : Controller
{
public ActionResult Index()
{
var model = new UserBLL();
var filler = new DBFiller();
filler.Filler();
List<Item> allItems = model.getItems();
return PartialView(allItems);
}
}
}
Index.cshtml 如果有帮助的话：
@using Oblig1
@model IEnumerable<Oblig1.Model.Item>
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
<br />
<br />
<br />
<head>
<title>Index</title>
<script src="~/Scripts/jquery-1.7.1.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
</head>
@if (Model != null)
{
<div class="row">
@foreach(var item in Model)
{
<div class="col-sm-6 col-md-3">
<div class="thumbnail">
<img src="@item.pictureURL" alt="...">
<div class="caption">
<h3>@item.itemname</h3>
<p>Antall på lager: @item.currentstock<br />kr @item.itemprice,00</p>
<button class="btn btn-success">@Html.ActionLink("Add to Cart", "AddToCart", new { id = item.itemid }, null)</button>
</div>
</div>
</div>
}
</div>
}
JS 尝试填充调用：
@model IEnumerable<Oblig1.Model.Item>
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
<br />
<br />
<br />
<head>
<title>Index</title>
<script src="~/Scripts/jquery-1.7.1.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script type="text/jscript">
$('#fill').click(function () {
var url = "/UserController/Filler";
$.post( url);
});
</script>
</head>
<button class="btn btn-success" id="fill" value="Fill Database"> </button>
控制器：
public ActionResult Filler()
{
var filler = new DBFiller();
filler.Filler();
return View("Index");
}
