Question

我有一个详细视图，其中会话，甚至会话中的评论框。我在局部视图中有一个评论框。但是在决定刷新关于创建评论的对话时遇到了问题。我知道我可以在局部视图中绑定下面的代码。但是我很难为它调用动作方法。所以它将有详细信息查看代码，然后是代码

<div class="row">

可以调用哪个方法来获取会话列表？我需要写一个新的动作方法。

Answer 1

您可以创建一个Action方法，返回您所拥有的对话的部分视图。例如：

public class SomeCtrlController : Controller
{
    public PartialViewResult Conversation(int id)
    {
        List<Conversation> conversations = new List<Conversation>();
        //Use id to create your Model and pass it to Partial View
        conversations = PopulateConversations(id);

        // The below code search for Conversation.cshtml inside Views\SomeCtrl folder
        return PartialView(conversations);
    }
}

然后从您的cshtml（剃刀视图）中，您可以像第一次加载一样调用它：

@{ Html.RenderAction("Conversation", "SomeCtrl", new { id = 1 /*this will be id for which conversion have to load */ });}

然后要刷新对话，您可以使用jQuery ajax或get方法。这将仅刷新您指定的部分。见下面的例子

<script>
    var conversationData = {
        "id": 1 /*this will be id for which conversion have to load */
    };
    $.get("/SomeCtrl/Conversation", conversationData,
          function (returnedHtml) {
              $("#placeHolderDivToHaveConversation").html(returnedHtml);
          });
</script>

Answer 2

当我需要这样做时，我使用jquery ajax。例如：

我需要动态加载以下div：

按钮视图

  <button id="buscarVideos" class="btn">Buscar</button>

我在一个事件中调用我的ajax并在那里加载de result：

成功ajax

 $("#partial_video").html(data);

部分

 <div class="col-lg-12">
            <div id="partial_video">
              @*@Html.Partial("_Player")*@
          </div>
   </div>

返回控制器：

  return PartialView("_Player", video);

刷新mvc中的局部视图
