成功后清除字段 [英] Clear fields after success

问题描述

我有一个页面，其中有2个输入type = text.

I have a page with 2 input type=text..

@model MVC3.ViewModel.TalkToUsVM

@using (Html.BeginForm())
{
    <ul>
        <li>@Html.TextBoxFor(m => m.TalkToUsRequest.Name)</li>
        <li>@Html.TextBoxFor(m => m.TalkToUsRequest.Email)</li>
    </ul>

    <input type="submit" value="Save"/>
}

在我的控制器中，我这样做:

in my controller I do this:

[HttpPost]
public ActionResult Create(TalkToUsRequest talkToUsRequest)
{
    var vm = new TalkToUsVM();

    if (TryValidateModel(talkToUsRequest))
    {
        vm.Result = "Success";

        return View("Create",vm);
    }

    vm = new TalkToUsVM
    {
        Result = "Errrooooooor",
        TalkToUsRequest = talkToUsRequest
    };

    return View(vm);
}

所以是问题..当我的模型有效时，我将结果设置为成功"，此时vm.TalkToUsRequest为null ..但是，呈现页面时，所有字段的值都与提交时的值相同..即使我设置vm.TalkToUsRequest = null！ 如何清除此字段?

so the problem.. when my model is valid, I set the result to "Success" and in this point vm.TalkToUsRequest is null.. but when page is rendered, all fields are with the same value that when I submited.. even I setting vm.TalkToUsRequest = null!! How can I clear this fields?

推荐答案

因此，在这种情况下，如果您返回同一视图，则必须清除模型状态. 尝试以下操作:

So in this scenario you have to clear your model state if you return back to the same view. Try following:

    ModelState.Clear();
    return View(vm);
}
