推荐答案

您实际上并不需要多个表单，也可以使用单个表单实现相同的表单.与往常一样，有多种方法可以实现这一目标.我给他们之一.看看下面的例子...

添加一个名为UserData的类，该类将包含具有验证规则的属性.

You don''t really need to have multiple forms and achieve the same using a single form. As always, there are multiple ways to achieve this. I am giving one of them. Check out the following example...

Add a class called UserData that would contain a property with validation rules.

public class UserData
{
    [Required(ErrorMessage="Name is required")]
    public string Name { get; set; }
}

以下是操作方法(用于初始显示和后操作):

The following are the action methods (for initial display and post action):

public ActionResult MultipleButtons()
{
    return View();
}

[HttpPost]
public ActionResult MultipleButtons(UserData userData, string submit)
{
    // "submit" variable has the button clicked
    if (submit == "Action 1")
    {
         // carry out activities to be performed for 1st button click
    }
    else
    {
         // carry out activities to be performed for 2nd button click
    }

    return View(userData);
}

最后，MultipleButtons视图如下所示:

Finally, the MultipleButtons view looks like this:

@model TestMvcApp3.Controllers.UserData

@using (Html.BeginForm())
{
    @Html.TextBoxFor(m => m.Name) @* Displays a text box and binds it to the "Name" property *@
    @Html.ValidationMessageFor(m => m.Name) @* Display validation messages if any *@

    <input type="submit" value="Action 1" name="submit" /><input type="submit" value="Action 2" name="submit" />
}

希望这会有所帮助！
