David Findley在他的ASP上写了3种不同的选择。网络博客。

阅读文章的多个按钮以相同的形式查看他的解决方案，以及每个方案的优缺点。恕我直言，他提供了一个非常优雅的解决方案，利用属性，你装饰你的行动。

我已经为HtmlHelper创建了一个ActionButton方法。它将在OnClick事件中生成带有javascript的普通输入按钮，将表单提交给指定的控制器/动作。

像这样使用辅助器

@Html.ActionButton("MyControllerName", "MyActionName", "button text")

这将生成以下HTML

<input type="button" value="button text" onclick="this.form.action = '/MyWebsiteFolder/MyControllerName/MyActionName'; this.form.submit();">

下面是扩展方法代码:

VB。网

<System.Runtime.CompilerServices.Extension()>
Function ActionButton(pHtml As HtmlHelper, pAction As String, pController As String, pRouteValues As Object, pBtnValue As String, pBtnName As String, pBtnID As String) As MvcHtmlString
    Dim urlHelperForActionLink As UrlHelper
    Dim btnTagBuilder As TagBuilder

    Dim actionLink As String
    Dim onClickEventJavascript As String

    urlHelperForActionLink = New UrlHelper(pHtml.ViewContext.RequestContext)
    If pController <> "" Then
        actionLink = urlHelperForActionLink.Action(pAction, pController, pRouteValues)
    Else
        actionLink = urlHelperForActionLink.Action(pAction, pRouteValues)
    End If
    onClickEventJavascript = "this.form.action = '" & actionLink & "'; this.form.submit();"

    btnTagBuilder = New TagBuilder("input")
    btnTagBuilder.MergeAttribute("type", "button")

    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript)

    If pBtnValue <> "" Then btnTagBuilder.MergeAttribute("value", pBtnValue)
    If pBtnName <> "" Then btnTagBuilder.MergeAttribute("name", pBtnName)
    If pBtnID <> "" Then btnTagBuilder.MergeAttribute("id", pBtnID)

    Return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal))
End Function

c# (c#代码只是从VB DLL中反编译的，所以它可以得到一些美化…但是时间太短了:-)

public static MvcHtmlString ActionButton(this HtmlHelper pHtml, string pAction, string pController, object pRouteValues, string pBtnValue, string pBtnName, string pBtnID)
{
    UrlHelper urlHelperForActionLink = new UrlHelper(pHtml.ViewContext.RequestContext);
    bool flag = Operators.CompareString(pController, "", true) != 0;
    string actionLink;
    if (flag)
    {
        actionLink = urlHelperForActionLink.Action(pAction, pController, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    else
    {
        actionLink = urlHelperForActionLink.Action(pAction, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    string onClickEventJavascript = "this.form.action = '" + actionLink + "'; this.form.submit();";
    TagBuilder btnTagBuilder = new TagBuilder("input");
    btnTagBuilder.MergeAttribute("type", "button");
    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript);
    flag = (Operators.CompareString(pBtnValue, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("value", pBtnValue);
    }
    flag = (Operators.CompareString(pBtnName, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("name", pBtnName);
    }
    flag = (Operators.CompareString(pBtnID, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("id", pBtnID);
    }
    return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal));
}

这些方法具有各种参数，但是为了便于使用，您可以创建一些重载，只使用所需的参数。

我建议感兴趣的人看看Maarten Balliauw的解决方案。我认为它非常优雅。

如果链接消失，它将使用应用于控制器操作的MultiButton属性来指示该操作应该与哪个按钮单击相关。

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();
}

下面是基于Maarten Balliauw的帖子和评论，针对多个提交按钮问题的一个非常干净的基于属性的解决方案。

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultipleButtonAttribute : ActionNameSelectorAttribute
{
    public string Name { get; set; }
    public string Argument { get; set; }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        var isValidName = false;
        var keyValue = string.Format("{0}:{1}", Name, Argument);
        var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);

        if (value != null)
        {
            controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
            isValidName = true;
        }

        return isValidName;
    }
}

剃须刀:

<form action="" method="post">
 <input type="submit" value="Save" name="action:Save" />
 <input type="submit" value="Cancel" name="action:Cancel" />
</form>

和控制器:

[HttpPost]
[MultipleButton(Name = "action", Argument = "Save")]
public ActionResult Save(MessageModel mm) { ... }

[HttpPost]
[MultipleButton(Name = "action", Argument = "Cancel")]
public ActionResult Cancel(MessageModel mm) { ... }

更新:Razor页面提供相同的功能开箱即用。对于新的开发来说，它可能更可取。

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();
    }

}
