将 ID 从 Foreach 传递到 Html.BeginForm

Question

我需要我的模型中的 ID @item.errorId 在提交表单时循环 foreach 以传递，因为必须将提交的表单跟踪回确切的行。

我尝试创建一个单页应用程序。

这是我创建表格的 CSHTML

   <tbody>
            @foreach (var item in Model.LogItems)
            {
                <tr href="#/" onclick="createTicket('@HttpUtility.JavaScriptStringEncode(item.Type)', '@HttpUtility.JavaScriptStringEncode(item.TimeUtc.ToString())', '@HttpUtility.JavaScriptStringEncode(item.Host)', '@HttpUtility.JavaScriptStringEncode(item.Message)', '@HttpUtility.JavaScriptStringEncode(item.Source)', '@HttpUtility.JavaScriptStringEncode(item.User)', '@HttpUtility.JavaScriptStringEncode(item.AllXml)', '@HttpUtility.JavaScriptStringEncode(item.ErrorId.ToString())')" style="cursor: pointer">
                    <td scope="row"> @(rowNo += 1) </td>
                    <td style="white-space: nowrap;">
                        @item.TimeUtc
                    </td>
                    <td style="word-wrap:break-word; max-width: 250px;">
                        @item.Type
                    </td>
                    <td>@item.Host</td>
                    <td style="max-width: 200px; word-wrap:break-word;"> @item.Message</td>
                    <td>
                        @item.Source
                    </td>
                    @if (item.User != "")
                    {
                        <td>@item.User</td>
                    }
                    else
                    {
                        <td><i>null</i></td>
                    }
                    <td>@item.AllXml.Split('"')[1].Split('"')[0]...</td>
                    <td style="white-space: nowrap;"> <button class="btn btn-link btn-xs">Dismiss</button></td>
                </tr>
            }
        </tbody>

Javascript 处理将值传递给innerHtml 并显示“窗口”的 onClick

  function createTicket(type, time, host, message, source, user, xml, errorid) {        

        if (ticketSwitch == true) {
                popup.style.visibility = "visible";
                cardHeader.innerHTML = type;
                timeForLogs.innerHTML = time;
                cardHost.innerHTML = host;
                cardMessage.innerHTML = message;
                cardSource.innerHTML = source;
                cardUser.innerHTML = user;
                cardText.innerText = xml;
                id.innerHTML = errorid;
                ticketSwitch = false;
            }
}

点击行后，我们得到这个

我们可以点击门票标签

这是 CSHTML BeginForm

 @using (Html.BeginForm("Index", "Ticket", FormMethod.Post))
            {
                <div>
                    <br />
                    <div style="background-color:#2C3E5070; color: white; padding: 3px; border-radius:3px; font-weight: 300;">
                        <a style="font-size: 0.9em">Create Issue</a>
                    </div>
                    <br />
                    <form>
                        <span style="font-size: 0.8em">Project<sup class="star">*</sup></span> @Html.DropDownListFor(m => model.fields.project.key, (IEnumerable<SelectListItem>)ViewBag.Projects, "<select>", new { @class = "form-control input-sm my-size-text-area input-background" })
                        <br />
                        <span style="font-size: 0.8em">Issue type</span> @Html.DropDownListFor(m => model.fields.issuetype.name, new List<SelectListItem> { new SelectListItem { Text = "Bug", Value = "Bug" }, new SelectListItem { Text = "Feature", Value = "Feature" }, new SelectListItem { Text = "Task", Value = "Task" }, }, new { @class = "form-control input-sm my-size-text-area input-background" })
                        <br />
                        <span style="font-size: 0.8em">Assignee<sup class="star">*</sup></span> @Html.DropDownListFor(m => model.fields.assignee.name, (IEnumerable<SelectListItem>)ViewBag.Users, "<select>", new { @class = "form-control input-sm my-size-text-area input-background" })
                        <br />
                        <span style="font-size: 0.8em">Summary<sup class="star">*</sup></span>@Html.TextBoxFor(m => model.fields.summary, new { @class = "form-control input-sm my-size-text-area input-background" })
                        <br />
                        <div class="form-group">
                            <span style="font-size: 0.8em">Description<sup class="star">*</sup></span> @Html.TextAreaFor(m => model.fields.description, 5, 60, new { @class = "form-control my-size-text-area input-background" })
                        </div>
                        <br />
                        <input style="font-size: 0.8em !important;" onclick="loadingOverlay()" id="Submit" class="btn btn-primary float-right" type="submit" value="Create" />
                    </form>
                </div>
            }

在提交票证时，我想将从 foreach 获得的 ID 传递到处理我的 POST 请求的控制器中。

最近我要做的就是将它作为一个值传递给

@using (Html.BeginForm("Index", "Ticket", FormMethod.Post))

但这总是会从最后一个 foreach 项目传递 id。

感谢所有帮助

试试这个。

1. 将errorid分配给cshtml中的隐藏字段

@Html.HiddenFor(model => m.errorId)

1. 访问控制器中的隐藏字段值。
