Question

II创建了一个动态表单，允许用户向表中添加行，其中包含用于输入的输入。

我想将字段数组绑定到操作中的模型。

我相信我已按照正确的命名程序进行任何其他行＆＃34; fieldName [0]＆＃34;

我创建了一个条目并发布到了操作但绑定没有发生

我检查了请求的标题，可以看到发布的信息

这里是表单数据：

CompanyAllId[0]: 0
EmployeeId[0]: 0
Name[0]: Test Name
Position[0]: Manager
MonthlyEarnings[0]: 10000
startDate[0]: 02/04/2018 17:58:00
EmploymentType[0]: Full Time

这是我的观点

<form asp-action="SaveEmployee">
    <table class="table table-bordered table-hover table-striped" id="employee-table">
        <thead>
            <tr>
                <th>
                    Name
                </th>
                <th>
                    Position
                </th>
                <th>
                    Monthly Earnings
                </th>
                <th>
                    Start Date
                </th>
                <th>
                    Employment Type
                </th>

        </thead>
        <tbody class="table-body">
            @for (int i = 0; i < Model.Count; i++)
            {
                <tr class="table-row" data-id="0">
                    @Html.Hidden("CompanyAllId[" + i + "]", Model[i].CompanyAllId)
                    @Html.Hidden("EmployeeId[" + i + "]", Model[i].EmployeeId)
                    <td> @Html.TextBox("Name[" + i + "]", Model[i].Name)</td>
                    <td>@Html.TextBox("Position[" + i + "]", Model[i].Position)</td>
                    <td>@Html.TextBox("MonthlyEarnings[" + i + "]", Model[i].MonthlyEarnings)</td>
                    <td>@Html.TextBox("startDate[" + i + "]", Model[i].startDate)</td>
                    <td>@Html.TextBox("EmploymentType[" + i + "]", Model[i].EmploymentType)</td>
            </tr>
        }
        </tbody>
    </table>
    <button class="clone-button btn btn-flat btn-primary">Add Row</button>
    <button type="submit" class="btn btn-flat btn-primary">Save</button>
</form>

控制器操作

[HttpPost]
[Authorize]
public async Task<IActionResult> SaveEmployee(List<Models.CompanyViewModels.Employees.Employee> vm)
{

    return View();
}

我相信我已遵循正确的命名

不，你没有。您必须为元素提供索引，而不是属性因此，如果您的参数名为vm：

@Html.Hidden("vm[" + i + "].CompanyAllId", Model[i].CompanyAllId)
@Html.Hidden("vm[" + i + "].EmployeeId", Model[i].EmployeeId)
<td> @Html.TextBox("vm[" + i + "].Name", Model[i].Name)</td>
<td>@Html.TextBox("vm[" + i + "].Position", Model[i].Position)</td>
<td>@Html.TextBox("vm[" + i + "].MonthlyEarnings", Model[i].MonthlyEarnings)</td>
<td>@Html.TextBox("vm[" + i + "].startDate", Model[i].startDate)</td>
<td>@Html.TextBox("vm[" + i + "].EmploymentType", Model[i].EmploymentType)</td>

所以，你应该最终得到像......

vm[0].CompanyAllId: 0
vm[0].EmployeeId: 0
vm[0].Name: Test Name
vm[0].Position: Manager
vm[0].MonthlyEarnings: 10000
vm[0].startDate: 02/04/2018 17:58:00
vm[0].EmploymentType: Full Time

ASP核心文本框数组在操作中没有绑定
