Modified version of HttpParamActionAttribute method but with a bug fix for not causing an error on expired/invalid session postbacks. To see if this is a problem with your current site, open the your form in a window and just before you go to click Save or Publish, open a duplicate window, and logout. Now go back to your first window and try to submit your form using either button. For me I got an error so this change solves that problem for me. I omit a bunch of stuff for the sake of brevity but you should get the idea. The key parts are the inclusion of ActionName on the attribute and making sure the name passed in is the name of the View that shows the form

属性类

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class HttpParamActionAttribute : ActionNameSelectorAttribute
{
    private readonly string actionName;

    public HttpParamActionAttribute(string actionName)
    {
        this.actionName = actionName;
    }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        if (actionName.Equals(methodInfo.Name, StringComparison.InvariantCultureIgnoreCase))
            return true;

        if (!actionName.Equals(this.actionName, StringComparison.InvariantCultureIgnoreCase))
            return false;

        var request = controllerContext.RequestContext.HttpContext.Request;
        return request[methodInfo.Name] != null;
    }
}

控制器

[Authorize(Roles="CanAddContent")]
public ActionResult CreateContent(Guid contentOwnerId)
{
    var viewModel = new ContentViewModel
    {
        ContentOwnerId = contentOwnerId
        //populate rest of view model
    }
    return View("CreateContent", viewModel);
}

[Authorize(Roles="CanAddContent"), HttpPost, HttpParamAction("CreateContent"), ValidateAntiForgeryToken]
public ActionResult SaveDraft(ContentFormModel model)
{
    //Save as draft
    return RedirectToAction("CreateContent");
}

[Authorize(Roles="CanAddContent"), HttpPost, HttpParamAction("CreateContent"), ValidateAntiForgeryToken]
public ActionResult Publish(ContentFormModel model)
{
    //publish content
    return RedirectToAction("CreateContent");
}

View

@using (Ajax.BeginForm("CreateContent", "MyController", new { contentOwnerId = Model.ContentOwnerId }))
{
    @Html.AntiForgeryToken()
    @Html.HiddenFor(x => x.ContentOwnerId)

    <!-- Rest of your form controls -->
    <input name="SaveDraft" type="submit" value="SaveDraft" />
    <input name="Publish" type="submit" value="Publish" />
}

Index.cshtml @using （Html.BeginForm（“Index”， “Home”， FormMethod.Post， new { id = “submitForm” }）） { 按钮类型=“提交” id=“btn批准” 名称=“命令” 值=“批准”>批准 按钮类型=“提交” id=“btn拒绝” 名称=“命令” 值=“拒绝”>拒绝 }

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Index(FormCollection frm, string Command)
    {
        if (Command == "Approve")
        {

        }
        else if (Command == "Reject")
        {

        }

        return View();
    }

}

你应该能够为按钮命名并赋予它们一个值;然后将此名称映射为操作的参数。或者，使用2个单独的动作链接或2个表单。

如果您的浏览器支持输入按钮的属性格式操作(IE 10+，不确定其他浏览器)，那么以下应该工作:

@using (Html.BeginForm()){
    //put form inputs here

<input id="sendBtn" value="Send" type="submit" formaction="@Url.Action("Name Of Send Action")" />

<input id="cancelBtn" value="Cancel" type="submit" formaction="@Url.Action("Name of Cancel Action") />

}

这是我发现的最好的方法:

代码如下:

    /// <summary>
    /// ActionMethodSelector to enable submit buttons to execute specific action methods.
    /// </summary>
    public class AcceptParameterAttribute : ActionMethodSelectorAttribute
   {
        /// <summary>
        /// Gets or sets the value to use to inject the index into
        /// </summary>
       public string TargetArgument { get; set; }

       /// <summary>
       /// Gets or sets the value to use in submit button to identify which method to select. This must be unique in each controller.
       /// </summary>
       public string Action { get; set; }

       /// <summary>
       /// Gets or sets the regular expression to match the action.
       /// </summary>
       public string ActionRegex { get; set; }

       /// <summary>
       /// Determines whether the action method selection is valid for the specified controller context.
       /// </summary>
       /// <param name="controllerContext">The controller context.</param>
       /// <param name="methodInfo">Information about the action method.</param>
       /// <returns>true if the action method selection is valid for the specified controller context; otherwise, false.</returns>
       public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo)
       {

           if (controllerContext == null)
           {
               throw new ArgumentNullException("controllerContext");
           }

           Func<NameValueCollection> formGetter;
           Func<NameValueCollection> queryStringGetter;

           ValidationUtility.GetUnvalidatedCollections(HttpContext.Current, out formGetter, out queryStringGetter);

           var form = formGetter();
           var queryString = queryStringGetter();

           var req = form.AllKeys.Any() ? form : queryString;

           if (!string.IsNullOrEmpty(this.ActionRegex))
           {
               foreach (var key in req.AllKeys.Where(k => k.StartsWith(Action, true, System.Threading.Thread.CurrentThread.CurrentCulture)))
               {
                   if (key.Contains(":"))
                   {
                       if (key.Split(':').Count() == this.ActionRegex.Split(':').Count())
                       {
                           bool match = false;
                           for (int i = 0; i < key.Split(':').Count(); i++)
                           {
                               if (Regex.IsMatch(key.Split(':')[0], this.ActionRegex.Split(':')[0]))
                               {
                                   match = true;
                               }
                               else
                               {
                                   match = false;
                                   break;
                               }
                           }

                           if (match)
                           {
                               return !string.IsNullOrEmpty(req[key]);
                           }
                       }
                   }
                   else
                   {
                       if (Regex.IsMatch(key, this.Action + this.ActionRegex))
                       {
                           return !string.IsNullOrEmpty(req[key]);
                       }
                   }

               }
               return false;
           }
           else
           {
               return req.AllKeys.Contains(this.Action);
           }
       }
   }

享受一个没有代码气味的多提交按钮的未来。

谢谢你！

使用自定义助手(创建一个“Helpers.”文件)。cshtml" App_Code文件夹内，在你的项目的根)用javascript重写(在一个'onclick'事件)表单的'动作'属性，你想要的东西，然后提交它。

助手可以是这样的:

@helper SubmitButton(string text, string controller,string action)
{   
    var uh = new System.Web.Mvc.UrlHelper(Context.Request.RequestContext);
    string url = @uh.Action(action, controller, null);   
    <input type=button  onclick="(
                                       function(e)
                                                 {
                                                   $(e).parent().attr('action', '@url'); //rewrite action url
                                                   //create a submit button to be clicked and removed, so that onsubmit is triggered
                                                   var form = document.getElementById($(e).parent().attr('id'));
                                                   var button = form.ownerDocument.createElement('input');
                                                   button.style.display = 'none';
                                                   button.type = 'submit';
                                                   form.appendChild(button).click(); 
                                                   form.removeChild(button);              
                                                  }
                                      )(this)" value="@text"/>
}

然后把它用作:

@Helpers.SubmitButton("Text for 1st button","ControllerForButton1","ActionForButton1")
@Helpers.SubmitButton("Text for 2nd button","ControllerForButton2","ActionForButton2")
...

在你的表单里面。
