Question

我有ComicPanel的编辑页面，其中包含ComicPanelText列表。

我想添加一个新的ComicPanelText，所以我需要一个“添加”按钮，但是提交按钮会转到我的EditController。如何添加新的提交按钮来确定在控制器中按下了哪个按钮？

查看/共享/ EditorTemplates / ComicPanelText.cshtml

@model ComicNet.Models.ComicPanelText

    <tr>
        <td></td>
        <td>
            @Html.HiddenFor(x => x.ComicPanelTextId)
            @Html.TextBoxFor(x => x.ComicText)
        </td>
    </tr>

查看/ ComicPanels / Edit.cshtml

@model ComicNet.Models.ComicPanel

@{
    ViewBag.Title = "Edit";
}

<h2>Edit</h2>

<form action="" method="post" enctype="multipart/form-data">
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true);

    <table>
        <tr>
            <td>
                @Html.LabelFor(m => m.Name)
            </td>
            <td>
                @Html.EditorFor(m => m.Name)
            </td>
        </tr>

        <tr>
            <td>
                @Html.LabelFor(m => m.PanelNumber)
            </td>
            <td>
                @Html.EditorFor(m => m.PanelNumber)
            </td>
        </tr>
        <tr>

            <td>
                <img src='@Html.DisplayFor(model => model.Url)' width="200" height="200" />

我猜您可以将按钮名称传递给Controller

  <input name="submit" type="submit" id="addText" value="Add" />



   public ActionResult Edit(ComicPanel comicPanel, string submit)
    {
        if(submit == "Add")
        {
            var newComicPanelText = new ComicPanelText();
            comicPanel.ComicPanelTexts.Add(newComicPanelText);
            db.Entry(newComicPanelText).State = EntityState.Added;
            db.Entry(comicPanel).State = EntityState.Modified; 
            db.SaveChanges();
            return View(comicPanel);
        }
