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。

视图中的代码是:

<script language="javascript" type="text/javascript">
    function SubmeterForm(id)
    {
        if (id=='btnOk')
            document.forms[0].submit(id);
        else
            document.forms[1].submit(id);
    }
</script>


<% Html.BeginForm("ObterNomeBotaoClicado/1", "Teste01", FormMethod.Post); %>
<input id="btnOk" type="button" value="Ok" onclick="javascript:SubmeterForm('btnOk')" />
<% Html.EndForm(); %>
<% Html.BeginForm("ObterNomeBotaoClicado/2", "Teste01", FormMethod.Post); %>
<input id="btnCancelar" type="button" value="Cancelar" onclick="javascript:SubmeterForm('btnCancelar')" />
<% Html.EndForm(); %>

在Controller中,代码是:

public ActionResult ObterNomeBotaoClicado(string id)
{
    if (id=="1")
        btnOkFunction(...);
    else
        btnCancelarFunction(...);
    return View();
}

我来派对已经很晚了,但现在开始… 我的实现借用了@mkozicki,但需要更少的硬编码字符串来出错。需要4.5+框架。实际上,控制器方法名应该是路由的关键。

标记。按钮名称必须以“action:[controllerMethodName]”为键

(注意使用c# 6的API名称,提供了对希望调用的控制器方法名称的特定类型引用。

<form>
    ... form fields ....
    <button name="action:@nameof(MyApp.Controllers.MyController.FundDeathStar)" type="submit" formmethod="post">Fund Death Star</button>
    <button name="action:@nameof(MyApp.Controllers.MyController.HireBoba)" type="submit" formmethod="post">Hire Boba Fett</button>
</form>

控制器:

namespace MyApp.Controllers
{
    class MyController
    {    
        [SubmitActionToThisMethod]
        public async Task<ActionResult> FundDeathStar(ImperialModel model)
        {
            await TrainStormTroopers();
            return View();
        }

        [SubmitActionToThisMethod]
        public async Task<ActionResult> HireBoba(ImperialModel model)
        {
            await RepairSlave1();
            return View();
        }
    }
}

属性的魔法。注意使用CallerMemberName功能。

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class SubmitActionToThisMethodAttribute : ActionNameSelectorAttribute
{        
    public SubmitActionToThisMethodAttribute([CallerMemberName]string ControllerMethodName = "")
    {
        controllerMethod = ControllerMethodName;
        actionFormat = string.Concat(actionConstant, ":", controllerMethod);
    }
    const string actionConstant = "action";
    readonly string actionFormat;
    readonly string controllerMethod;

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        var isValidName = false;
        var value = controllerContext.Controller.ValueProvider.GetValue(actionFormat);

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

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。

如果你对HTML 5的使用没有限制,你可以使用带有formaction的<button>标签:

<form action="demo_form.asp" method="get">
   First name: <input type="text" name="fname" /><br />
   Last name: <input type="text" name="lname" /><br />
   <button type="submit">Submit</button><br />
   <button type="submit" formaction="demo_admin.asp">Submit as admin</button>
</form>

参考:http://www.w3schools.com/html5/att_button_formaction.asp

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());
}
