ASP.NET MVC当作ajaxForm不能正常更新局部视图 [英] ASP.NET MVC AjaxForm not updating partial view properly

问题描述

我不知道我做错了。我以前从未有过这个问题，或者也许我有，但我从来没有注意到。我有一个局部视图的页面。当页面被提交时，该模型被检查，看它是否具有一个ID。如果这样做，更新记录。如果不是，它会创建一个新的。 pretty标准。一旦完成，该模型被返回到视图。我似乎具有的问题是，它没有被更新的任何改变模型。这只是被张贴相同的模型。好了，所以这里是一些code。我创建了一个全新的项目，它仍然无法正常工作。

I'm not sure what I am doing wrong. I have never had this problem before or maybe I have, but I've never noticed. I have a page with a partial view. When the page is submitted, the model is checked to see if it has an ID. If it does, it updates the record. If not, it creates a new one. Pretty standard. Once it is done, the model is returned back to the view. The problem I seem to be having is that it isn't updated with any changes to the model. It is just the same model that was posted. Okay so here is some code. I created a brand new project and it still doesn't work.

另外，我用萤火虫来看看原始数据回来，它仍然是相同的模型。

Also, I used Firebug to look at the raw data coming back and it is still the same model.

下面是控制器：

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Test()
{
    return this.View(new Test());
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult TestDetailPost(Test testin)
{
    Test test = new Test();
    test.Id = "1";
    test.Name = "Guy";

    return this.PartialView("TestDetail", test);
}

下面是测试的观点：

@model WebAppTest.Models.Test
@using (Ajax.BeginForm("TestDetailPost", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "TestDetail" }))
{
    <p><input type="submit"/></p>
    <div id="TestDetail">
        @{ Html.RenderPartial("TestDetail", Model); }
    </div>
}

下面是测试详细信息查看：

Here is the "Test Detail" view:

@model WebAppTest.Models.Test
<p>@Html.TextBoxFor(a => a.Id)</p>
<p>@Html.TextBoxFor(a => a.Name)</p>

和模型：

public class Test
{
    public string Id { get; set; }

    public string Name { get; set; }
}

所以，我发现是，如果我从TestDetailPost动作去掉测试TESTIN，则返回我创建的模型。如果我不这样做，它只是返回被张贴相同的模型。当然，我没有做任何数据库保存或任何内容，code以上仅仅是试图找出为什么发生这种情况。

So what I have found is that if I remove the "Test testin" from the TestDetailPost action, it returns the model I created. If I don't, it just returns the same model that was posted. Of course, I am not doing any DB saves or anything, the code above is just for trying to figure out why this is happening.

下面是我在用的细节：

MVC5
jQuery的1.11.1
jquery.unobtrusive阿贾克斯

MVC5 jQuery 1.11.1 jquery.unobtrusive-ajax

我已经更新使用的NuGet到最新版本的所有文件。

I have updated all files to the latest version using NuGet.

推荐答案

呼叫 ModelState.Clear（）; 在你的操作方法如下图所示：

Call ModelState.Clear(); in your action method like below:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult TestDetailPost(Test testin)
{
   ModelState.Clear();
   Test test = new Test();
   test.Id = "1";
   test.Name = "Guy";

   return this.PartialView("TestDetail", test);
}
