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。

如果您的浏览器支持输入按钮的属性格式操作(IE 10+,不确定其他浏览器),那么以下应该工作:
@using (Html.BeginForm()){
//put form inputs here
<input id="sendBtn" value="Send" type="submit" formaction="@Url.Action("Name Of Send Action")" />
<input id="cancelBtn" value="Cancel" type="submit" formaction="@Url.Action("Name of Cancel Action") />
}

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。
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')" >
[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>
}
//model
public class input_element
{
public string Btn { get; set; }
}
//views--submit btn can be input type also...
@using (Html.BeginForm())
{
<button type="submit" name="btn" value="verify">
Verify data</button>
<button type="submit" name="btn" value="save">
Save data</button>
<button type="submit" name="btn" value="redirect">
Redirect</button>
}
//controller
public ActionResult About()
{
ViewBag.Message = "Your app description page.";
return View();
}
[HttpPost]
public ActionResult About(input_element model)
{
if (model.Btn == "verify")
{
// the Verify button was clicked
}
else if (model.Btn == "save")
{
// the Save button was clicked
}
else if (model.Btn == "redirect")
{
// the Redirect button was clicked
}
return View();
}
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();
}
