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JQuery方法使用扩展方法:
public static MvcHtmlString SubmitButtonFor<TController>(this HtmlHelper helper, Expression<Action<TController>> action, string value) where TController : Controller
{
RouteValueDictionary routingValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action);
var onclick = string.Format("$('form').first().attr('action', '/{0}')", string.Join("/", routingValues.Values.ToArray().Where(x => x != null).Select(x => x.ToString()).ToArray()));
var html = "<input type=\"submit\" value=\"" + value + "\" onclick=\"" + onclick + "\" />";
return MvcHtmlString.Create(html);
}
你可以这样使用它:
@(Html.SubmitButtonFor<FooController>(c => c.Save(null), "Save"))
它是这样渲染的:
<input type="submit" value="Save" onclick="$('form').first().attr('action', '/Foo/Save')" >
其他回答
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。
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。
Eilon建议你可以这样做:
If you have more than one button you can distinguish between them by giving each button a name: <input type="submit" name="SaveButton" value="Save data" /> <input type="submit" name="CancelButton" value="Cancel and go back to main page" /> In your controller action method you can add parameters named after the HTML input tag names: public ActionResult DoSomeStuff(string saveButton, string cancelButton, ... other parameters ...) { ... } If any value gets posted to one of those parameters, that means that button was the one that got clicked. The web browser will only post a value for the one button that got clicked. All other values will be null. if (saveButton != null) { /* do save logic */ } if (cancelButton != null) { /* do cancel logic */ }
我喜欢这个方法,因为它不依赖于提交按钮的值属性,这个属性比分配的名称更有可能改变,并且不需要启用javascript

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());
}
[HttpPost]
public ActionResult ConfirmMobile(string nameValueResend, string nameValueSubmit, RegisterModel model)
{
var button = nameValueResend ?? nameValueSubmit;
if (button == "Resend")
{
}
else
{
}
}
Razor file Content:
@using (Html.BeginForm()
{
<div class="page registration-result-page">
<div class="page-title">
<h1> Confirm Mobile Number</h1>
</div>
<div class="result">
@Html.EditorFor(model => model.VefificationCode)
@Html.LabelFor(model => model.VefificationCode, new { })
@Html.ValidationMessageFor(model => model.VefificationCode)
</div>
<div class="buttons">
<button type="submit" class="btn" name="nameValueResend" value="Resend">
Resend
</button>
<button type="submit" class="btn" name="nameValueSubmit" value="Verify">
Submit
</button>
</div>
</div>
}
