Question

我在索引页面上的.NET应用程序中实现了一个保存按钮。当我点击它，它加载，但不保存任何东西。我只是使用索引页面的复选框。如果我取消选中并保存它，它会保存，但也会取消选中该行中的所有其他内容。当我尝试检查某些东西时没有任何反应。这是我正在使用的代码：

Index.cshtml

@using (Html.BeginForm("save", "drnos"))
{
    <input type="submit" value="Save" />
}

我的一个复选框字段的示例：

<td>
    @Html.EditorFor(modelItem => item.Soft)
    @Html.ValidationMessageFor(modelItem => item.Soft)
</td>

drnosController.cs

[HttpPost]
public ActionResult save(Doctor doc)
{
    System.Diagnostics.Debug.WriteLine("Save Called");
    db.Entry(doc).State = EntityState.Modified;
    db.SaveChanges();
    return RedirectToAction("Index");  
}

以下是整个HTML文件：

@model PagedList.IPagedList<drnosv6.Models.Doctor>
@using PagedList.Mvc;

<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />


@{
    ViewBag.Title = "Index";
}

<h2>Doctors</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm()) //insert the search bar
{
    <p>
        Find by First Name, Last Name, or RVH ID: @Html.TextBox("SearchString")

        <input type="submit" value="Search" />

    </p>
}

@using (Html.BeginForm("save", "drnos"))
{
    <input type="submit" value="Save" />
}

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('tr:even').addClass('alt-row-class');
    });

</script>

<p>    
</p>

<p>Click on a column header to sort by that column</p>

    <tr>

Answer 1

您的BeginForm或ActionLink必须指向ActionResult Edit。

Answer 2

提交表单时，只提交在该表单中声明的输入。您的表单中只有提交按钮，因此没有其他字段可以填写您的Doctor结构。您需要将保存按钮放在与所有其他字段相同的表单上。

ASP.NET MVC保存按钮加载但不起作用
