Update partial view after submit Ajax.Beginform
提问by Andreas
I am new at .NET mvc.
我是 .NET mvc 的新手。
In a view "DisplayThings" I have something like:
在“DisplayThings”视图中，我有类似的东西：
@foreach (var thing in Model)
{
@Html.Partial("DisplayPartial", thing)
}
In the partial view "DisplayPartial" I have
在局部视图“DisplayPartial”中，我有
@using (Ajax.BeginForm("Afunc", new AjaxOptions ()))
{
@Html.EditorFor(model => model.AstringThing)
@Html.EditorFor(model => model.AintThing)
<input type="submit" name="submit" value="Ajax Post" />
}
At the moment the "Afunc"-Action saves the model to the database and then redirects to a controller action to retrieve all "things" from the database and render the entire "Displaythings" View.
目前，“Afunc”-Action 将模型保存到数据库，然后重定向到控制器操作以从数据库中检索所有“事物”并呈现整个“Displaythings”视图。
My question is: When i press one of the submitbuttons (There is one submitbutton for every "thing" i the list). I want only that partial view to reload/reflect on my change. I dont want to reload the entire "Displaythings" view. How do I do this? If I just return a partial view I lose everything else but that partial view.
我的问题是：当我按下其中一个提交按钮时（列表中的每个“事物”都有一个提交按钮）。我只希望该部分视图重新加载/反映我的更改。我不想重新加载整个“Displaythings”视图。我该怎么做呢？如果我只是返回一个局部视图，除了那个局部视图之外，我会失去其他一切。
If this is a bad approach please give me directions.
如果这是一个不好的方法，请给我指示。
Update:
更新：
I am still doing something wrong as I get the partial view rendered in a new page. My controller :
当我在新页面中呈现部分视图时，我仍然做错了什么。我的控制器：
public ActionResult Afunc(ThingModel thingmodel)
{
// do
return PartialView("DisplayPartial", thingmodel);
}
I have tried using UpdateTargetId and onsuccess both with the same result (A new page)
我尝试使用 UpdateTargetId 和 onsuccess 都得到相同的结果（新页面）

In the AjaxOptionsthat your are simply now passing as new AjaxOptionsyou can specify the target element using the UpdateTargetIdproperty:
在AjaxOptions你的只是现在正在为new AjaxOptions您可以使用指定目标元素UpdateTargetId属性：
<div id="unique_thing_id">
@using (Ajax.BeginForm("Afunc", new AjaxOptions { UpdateTargetId = 'unique_thing_id' }))
{
}
</div>
Above, a container with unique id for every "thing" is represented with <div id="unique_thing_id">. This will be replaced with the repsonse of the request. Change Afuncto render only the particular "thing" partial.
上面，每个“事物”都具有唯一 id 的容器用<div id="unique_thing_id">. 这将替换为请求的响应。更改Afunc为仅呈现特定的“事物”部分。
