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。

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。

以下是最适合我的方法:

<input type="submit" value="Delete" name="onDelete" />
<input type="submit" value="Save" name="onSave" />


public ActionResult Practice(MyModel model, string onSave, string onDelete)
{
    if (onDelete != null)
    {
        // Delete the object
        ...
        return EmptyResult();
    }

    // Save the object
    ...
    return EmptyResult();
}

对于每个提交按钮,只需添加:

$('#btnSelector').click(function () {

    $('form').attr('action', "/Your/Action/);
    $('form').submit();

});

给你的提交按钮一个名字,然后在你的控制器方法中检查提交的值:

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

发布到

public class MyController : Controller {
    public ActionResult MyAction(string submitButton) {
        switch(submitButton) {
            case "Send":
                // delegate sending to another controller action
                return(Send());
            case "Cancel":
                // call another action to perform the cancellation
                return(Cancel());
            default:
                // If they've submitted the form without a submitButton, 
                // just return the view again.
                return(View());
        }
    }

    private ActionResult Cancel() {
        // process the cancellation request here.
        return(View("Cancelled"));
    }

    private ActionResult Send() {
        // perform the actual send operation here.
        return(View("SendConfirmed"));
    }

}

编辑:

要将此方法扩展到本地化站点,请将您的消息隔离在其他地方(例如将资源文件编译为强类型资源类)

然后修改代码,使其像这样工作:

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

你的控制器应该是这样的:

// Note that the localized resources aren't constants, so 
// we can't use a switch statement.

if (submitButton == Resources.Messages.Send) { 
    // delegate sending to another controller action
    return(Send());

} else if (submitButton == Resources.Messages.Cancel) {
     // call another action to perform the cancellation
     return(Cancel());
}

基于mkozicki的答案,我提出了一个有点不同的解决方案。我仍然使用ActionNameSelectorAttribute,但我需要处理两个按钮“保存”和“同步”。它们做的几乎是一样的,所以我不想有两个动作。

属性:

public class MultipleButtonActionAttribute : ActionNameSelectorAttribute
{        
    private readonly List<string> AcceptedButtonNames;

    public MultipleButtonActionAttribute(params string[] acceptedButtonNames)
    {
        AcceptedButtonNames = acceptedButtonNames.ToList();
    }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {            
        foreach (var acceptedButtonName in AcceptedButtonNames)
        {
            var button = controllerContext.Controller.ValueProvider.GetValue(acceptedButtonName);
            if (button == null)
            {
                continue;
            }                
            controllerContext.Controller.ControllerContext.RouteData.Values.Add("ButtonName", acceptedButtonName);
            return true;
        }
        return false;
    }
}

view

<input type="submit" value="Save" name="Save" />
<input type="submit" value="Save and Sync" name="Sync" />

控制器

 [MultipleButtonAction("Save", "Sync")]
 public ActionResult Sync(OrgSynchronizationEditModel model)
 {
     var btn = this.RouteData.Values["ButtonName"];

我还想指出,如果动作做不同的事情,我可能会遵循mkozicki的帖子。

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。
