问题描述

这是观点:



This is the view :

@foreach (var module in Model)
    {
        if (module.Placeholder == "head")
        {
            
            Html.RenderAction(module.Control, "ContentHtml", module.Content);





        }


        <br />
    }









这是控制器:







And this is the controller :

public ActionResult Tabelar2(string content)
      {

              var movies = db.ContentHtmls.Where(s => s.Content.Contains(content));





          return View(movies);
      }







仅当我设置内容'test1时才有效'在url中,示例localhost:58881 / Home / About / test1,我想要的是如何在此行中将module.Content字段读入数据库




This works only when i set the content 'test1' in the url , example localhost:58881/Home/About/test1 , what I want is how to read the module.Content field into database in this row

Html.RenderAction(module.Control, "ContentHtml", module.Content);

,然后将该值传递给控制器​​

, and then pass that value into the controller

public ActionResult Tabelar2(string content)

,因此它只显示带有该值的新闻内容。这行

, so it can show only the News with that content. This line

Html.RenderAction(module.Control, "ContentHtml", module.Content);

转到ContentHtml控制器,转到基于module.Control的特定Action,在本例中为Tabelar2,路由值应该是module.Content。



我尝试了什么:



我刚刚解释了上面的问题

goes to ContentHtml controller , to the certain Action based on module.Control , in this case Tabelar2 , and the route values should be the module.Content.

What I have tried:

I just explained the problem above

推荐答案

您需要将POST BACK数据封装在FORM中。



You need to encapsulate the POST BACK data in a FORM.

@using (Html.BeginForm()) {
    <p>
        <!-- Fields to post back go here -->
        <input type="submit" value="Delete" /> |
    </p>
}
