onclick 按钮保存数据 .cshtml

Question

我有一个 asp.net mvc razor 文件。按钮需要向数据库发送数据。这是我的代码。数据库已连接并在服务器上运行。我只是无法获得将数据发送到数据库的按钮。我尝试过使用 javascript 的 onclick 事件，但似乎没有任何效果。有人可以解释我应该怎么做吗？这是我第一次使用 .cshtml，我真的不知道如何解决这个问题。

问题已解决。 我使用了错误的名称..我在 .cshtml 的 C# 部分中提到了输入的 id 而不是名称..

@{
Validation.RequireField("achternaam", "Achternaam is verplicht.");
Validation.RequireField("voornaam", "Voornaam is verplicht.");
Validation.RequireField("organisatie", "Organisatie is verplicht.");
Validation.RequireField("email", "Email is verplicht.");
Validation.RequireField("datum", "Datum is verplicht.");
Validation.RequireField("tijd", "Tijd is verplicht.");

var achternaam = "";
var voornaam = "";
var organisatie = "";
var email = "";
var datum = "";
var tijd = "";

if (IsPost && Validation.IsValid())
{
    achternaam = Request.Form["achternaam"];
    voornaam = Request.Form["voornaam"];
    organisatie = Request.Form["organisatie"];
    email = Request.Form["email"];

    tijd = Request.Form["tijd"];


    using (var db = new Blub._1.Database.blubEntities())
    {
        // Insert

Answer 1

我认为您必须有一个带有如下操作的表单标签：

<form method="post" action="/ControllerName/ActionName">

或者按照#Kypaz 的建议使用助手：

@using (Html.BeginForm("ActionName", "ControllerName", null (adapt to route), FormMethod.Post))
{

 <input type="submit" value="Submit"/>  

}

Answer 2

最好的方法是使用 url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >
