为每个带有ID的产品制作页面

我的问题是,我想以最简单的方式为每个ID都存储在数据库中的产品制作一个页面

示例:

首页/产品/“数据库中的产品ID”

并且此链接必须显示产品的“详细信息” ^

目的是当我添加新产品时,会自动创建一个带有产品ID的新页面。

控制器中的操作代码:

[HttpPost]
    public ActionResult AddArticle(NewsData art)
    {
        var ArticleID = art.ArticleID;

        using (MatrodyEntities db = new MatrodyEntities())
        {
            db.NewsData.Add(art);
            db.SaveChanges();
        }

        return View(art);
    }

RouteConfig:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

好的,因此,为了基于参数建立CRUD操作的链接,您可以使用AJAX通过参数来发布数据,也可以使用Html.ActionLink而不是POST而是创建一个锚标签。

1)使用带有参数的ActionLink:

@foreach (var item in Model)
    {
        <tr>
        //Additional data
            <td>
                @Html.ActionLink("Delete", "Home", new { id = item.id})
            </td>
        </tr>
    }

在您的Home控制器中:

public ActionResult Delete(int id) {//Your logic}

请注意,如果您使用默认的RouteConfig,请确保将id作为参数发送,或者可以根据需要创建自己的路由。

2)您还可以使用AJAX POST到Controller。您可以执行以下操作:

@foreach (var item in Model)
    {
        <tr>
        //Additional data
            <td>
               <a href="#" data-id="@item.id" onclick="confirmDelete(this)"></a>
            </td>
        </tr>
    }

在您的AJAX中:

    function confirmDelete(event) {
        var recordToDelete = $(event).attr("data-id"); //Get our current file id here

        if (confirm("Are you sure you want to delete this record") == true) {
            //Prepare our data
            var json = {
                id: recordToDelete
            };

            $.ajax({
                url: '@Url.Action("DeleteFile", "Home")',
                type: "POST",
                dataType: "json",
                data: { "json": JSON.stringify(json) },
                success: function (data) {
                    if(data == "success") {
                        alert("Successfully deleted selected file");
                        location.reload();
                    }                        
                },
                error: function (data) {
                    alert("Could not delete selected file. Please try again!");
                },
            });
        }
    };

最后在您的控制器中:

//Delete a file based on the ID that you get from your View
[HttpPost]
public JsonResult DeleteFile(string json)
{
    var serializer = new JavaScriptSerializer();
    try
    {               
        dynamic jsondata = serializer.Deserialize(json, typeof(object));
        string id = jsondata["id"];
        if(id != "")
        {             
            int getid = Convert.ToInt32(id);
            //Call your db or your logic to delete the file
            DatabaseAccess data = new DatabaseAccess();
            string result = data.DeleteFile(getid);

            if(result.Equals("Success"))
            {
                return Json("success", JsonRequestBehavior.AllowGet);
            }
            else
            {
                return Json("fail", JsonRequestBehavior.AllowGet);
            }                     
        }
        else
        {
            return Json("notfound", JsonRequestBehavior.AllowGet);
        }
    }
    catch
    {
       return Json("dberror", JsonRequestBehavior.AllowGet);
    }
}
