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。

Modified version of HttpParamActionAttribute method but with a bug fix for not causing an error on expired/invalid session postbacks. To see if this is a problem with your current site, open the your form in a window and just before you go to click Save or Publish, open a duplicate window, and logout. Now go back to your first window and try to submit your form using either button. For me I got an error so this change solves that problem for me. I omit a bunch of stuff for the sake of brevity but you should get the idea. The key parts are the inclusion of ActionName on the attribute and making sure the name passed in is the name of the View that shows the form
属性类
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class HttpParamActionAttribute : ActionNameSelectorAttribute
{
private readonly string actionName;
public HttpParamActionAttribute(string actionName)
{
this.actionName = actionName;
}
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
if (actionName.Equals(methodInfo.Name, StringComparison.InvariantCultureIgnoreCase))
return true;
if (!actionName.Equals(this.actionName, StringComparison.InvariantCultureIgnoreCase))
return false;
var request = controllerContext.RequestContext.HttpContext.Request;
return request[methodInfo.Name] != null;
}
}
控制器
[Authorize(Roles="CanAddContent")]
public ActionResult CreateContent(Guid contentOwnerId)
{
var viewModel = new ContentViewModel
{
ContentOwnerId = contentOwnerId
//populate rest of view model
}
return View("CreateContent", viewModel);
}
[Authorize(Roles="CanAddContent"), HttpPost, HttpParamAction("CreateContent"), ValidateAntiForgeryToken]
public ActionResult SaveDraft(ContentFormModel model)
{
//Save as draft
return RedirectToAction("CreateContent");
}
[Authorize(Roles="CanAddContent"), HttpPost, HttpParamAction("CreateContent"), ValidateAntiForgeryToken]
public ActionResult Publish(ContentFormModel model)
{
//publish content
return RedirectToAction("CreateContent");
}
View
@using (Ajax.BeginForm("CreateContent", "MyController", new { contentOwnerId = Model.ContentOwnerId }))
{
@Html.AntiForgeryToken()
@Html.HiddenFor(x => x.ContentOwnerId)
<!-- Rest of your form controls -->
<input name="SaveDraft" type="submit" value="SaveDraft" />
<input name="Publish" type="submit" value="Publish" />
}

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)

}
return View();
}
}
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。
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());
}
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。
对于每个提交按钮,只需添加:
$('#btnSelector').click(function () {
$('form').attr('action', "/Your/Action/);
$('form').submit();
});
