问你如何处理ASP.NET MVC框架中的多个提交按钮？

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>

<input type="submit" name="submitButton" value="Send" />

<input type="submit" name="submitButton" value="Cancel" />

<% Html.EndForm(); %>

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"));

    }

}

<% 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(); %>

// 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());

}
