在mvc中刷新部分视图

本文关键字:视图 刷新部 mvc | 更新日期: 2023-09-27 18:20:45

我有一个详细视图,其中将有一个对话,甚至对话中的评论框。我有一个局部视图的评论框。但当决定只刷新创建评论的对话时,出现了问题。我知道我可以在部分视图中绑定以下代码。但我很难调用它的操作方法。所以它将有详细的视图代码,然后下面的代码

<div class="row">
    <div class="panel-group" id="accordion">
        @foreach (var convo in Model.TicketConversation.OrderByDescending(x => x.LastUpdatedTimestamp))
        {
            <div class="col-md-10 col-md-offset-1" style="padding-bottom: 5px;">
                <div class="panel panel-default">
                    <div class="panel-heading removePaddingBottom" data-toggle="collapse" data-target="#accord-convo-@convo.id" style="background-color: inherit;" id="accordHeading-@convo.id" onclick="javascript:showHideLastConvoMsg(@convo.id)">
                        <a style="text-decoration: none !important; color: inherit; width: 100px;">

可以调用哪种方法来获取对话列表??我需要写一个新的动作方法吗。

在mvc中刷新部分视图

您可以创建一个Action方法,该方法返回您所进行对话的部分视图。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);
    }
}

然后从你的cshtml(剃刀视图),你可以称之为第一次加载:

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

然后,为了只刷新对话,您可以使用jQueryajax或get方法。这将只刷新您指定的部分。参见以下示例

<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>

当我需要这样做时,我使用jquery ajax。例如:

我需要在下面动态加载这个div:

按钮视图

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

我在一个事件中调用我的ajax,并在那里加载反结果:

成功ajax

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

部分

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

控制器返回

  return PartialView("_Player", video);
