是否有一些简单的方法来处理来自同一个表单的多个提交按钮?例如:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" value="Send" />
<input type="submit" value="Cancel" />
<% Html.EndForm(); %>

知道如何在ASP中做到这一点吗?NET框架测试版?我在谷歌上搜索的所有例子中都有单个按钮。

我的解决方案是使用2个asp面板:

< asp:面板ID = " . . "DefaultButton = " ID_OF_SHIPPING_SUBMIT_BUTTON "…> < / asp:面板>

这是我发现的最好的方法:

http://iwayneo.blogspot.co.uk/2013/10/aspnet-mvc-action-selector-with-list.html

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!

您可以像前面提到的那样检查动作中的名称,但是您可能会考虑这是否是好的设计。考虑动作的职责,不要将这种设计过多地与按钮名称等UI方面结合起来,这是一个好主意。所以考虑使用两种形式和两种动作:

<% Html.BeginForm("Send", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Send" />
<% Html.EndForm(); %>

<% Html.BeginForm("Cancel", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Cancel" />
<% Html.EndForm(); %>

此外,在“取消”的情况下,您通常只是不处理表单,而是转到一个新的URL。在这种情况下,你根本不需要提交表单,只需要一个链接:

<%=Html.ActionLink("Cancel", "List", "MyController") %>

你可以这样写:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Send" />
<input type="submit" name="button" value="Cancel" />
<% Html.EndForm(); %>

然后在页面中检查name == "Send"或者name == "Cancel"…

我的解决方案是使用2个asp面板:

< asp:面板ID = " . . "DefaultButton = " ID_OF_SHIPPING_SUBMIT_BUTTON "…> < / asp:面板>

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。
