以下是我的视图代码，我将列表从控制器传递到视图，在这里我通过 foreach 迭代该列表我想在提交表单时将相同的视图模型列表传递给操作
@model IEnumerable<AskQuestionViewModel>
.
.
.
<table class="table table-bordered">
<thead>
<tr>
<td>Question</td>
<td>Yes</td>
<td>No</td>
</tr>
</thead>
<tbody>
@foreach (var q in Model)
{
<tr>
<td>@q.Question</td>
@if (q.Answer == true)
{
<td><input type="radio" name="@q.QuestionID" value="true" checked />/td>
}
else
{
<td><input type="radio" [email protected] value="true" required /></td>
}
@if (q.Answer == false)
{
<td><input type="radio" [email protected] value="false" checked /></td>
}
else
{
<td><input type="radio" [email protected] value="false" required /></td>
}
</tr>
}
以下是动作代码
[HttpPost]
public ActionResult AskQuestions(List<AskQuestionViewModel> askQVM)
{
...
}
我在 askQVM 中为空
这是回发所需要的。
<table class="table table-bordered">
<thead>
<tr>
<td>Question</td>
<td>Yes</td>
<td>No</td>
</tr>
</thead>
<tbody>
@using (Html.BeginForm("AskQuestions", "Questions", FormMethod.Post))
{
for (int i = 0; i < Model.Count; i++)
{
var yesOptions = Model[i].Answer ? new { @checked = "checked" } : null;
var noOptions = Model[i].Answer ? null : new { @checked = "checked" };
<tr>
<td>
@Model[i].Question
@Html.HiddenFor(model=>Model[i].QuestionID)
@Html.HiddenFor(model=>Model[i].Question)
</td>
<td>@Html.RadioButtonFor(model => Model[i].Answer, true, yesOptions)</td>
<td>@Html.RadioButtonFor(model => Model[i].Answer, false, noOptions)</td>
</tr>
}
<button type="submit">Submit</button>
}
</tbody>
