在单个表单中使用两个提交按钮

I have a form with two submit buttons in my asp.net mvc (C#) application. When i click any submit button in Google Chrome, by default the value of submit button is the first submit button's value.

我的asp.net mvc(C#)应用程序中有一个带有两个提交按钮的表单。当我点击谷歌浏览器中的任何提交按钮时,默认情况下,提交按钮的值是第一个提交按钮的值。

Here is the html:

这是html:

 <input type="submit" value="Send" name="SendEmail" />
 <input type="submit" value="Save As Draft" name="SendEmail" />
 <input type="button" value="Cancel" />

When i click the Save As Draft button, in the action of the controller, it gets "Send" as the value for SendEmail.

当我单击“另存为草稿”按钮时,在控制器的操作中,它将获得“发送”作为SendEmail的值。

Here is the action:

这是行动:

public ActionResult SendEmail(string SendEmail, FormCollection form)
 {
       if(SendEmail == "Send")
       {
          //Send Email
       }
       else
       {
          //Save as draft
       }
       return RedirectToAction("SendEmailSuccess");
 }

When i get the value from FormCollection, it shows "Send". i.e. form["SendEmail"] gives Send

当我从FormCollection获取值时,它显示“发送”。即form [“SendEmail”]给出发送

What may be the problem or work around i need to do to get the actual value of the clicked submit button?

我需要做什么才能获得点击提交按钮的实际值?

Try this instead:

试试这个:

<input type="submit" value="Send" name="send" />
<input type="submit" value="Save As Draft" name="save" />

and:

public ActionResult SendEmail(string send, FormCollection form)
{
    if (!string.IsNullOrEmpty(send))
    {
        // the Send button has been clicked
    } 
    else
    {
        // the Save As Draft button has been clicked
    }
}

Hidden Html elements will be submitted with your form, so you could add a hidden element and modify it on button click before submission. Return true to continue with form submission.

隐藏的Html元素将与您的表单一起提交,因此您可以在提交之前添加隐藏元素并在按钮单击时进行修改。返回true表示继续提交表单。

@Html.Hidden("sendemail", true)
<input type="submit" value="Send"
       onclick="$('#sendemail').val(true); return true" />
<input type="submit" value="Save As Draft"
       onclick="$('#sendemail').val(false); return true;" />

Now you can just pull the value out of your form collection.

现在,您可以从表单集中提取值。

public ActionResult SendEmail(FormCollection form)
{
   if(Boolean.Parse(form["sendemail"]))
   {
      //Send Email
   }
   else
   {
      //Save as draft
   }
   return RedirectToAction("SendEmailSuccess");
}

Rather than using the FormCollection directly though, the best practice would be to create a view model that contains the specified property.

但不是直接使用FormCollection,最佳做法是创建包含指定属性的视图模型。

View Model

public class FooViewModel
{
  public bool SendEmail { get; set; }
  // other stuff
}

HTML

// MVC sets a hidden input element's id attribute to the property name, 
// so it's easily selectable with javascript
@Html.HiddenFor(m => m.SendEmail)

// a boolean HTML input can be modified by setting its value to
// 'true' or 'false'
<input type="submit" value="Send"
       onclick="$('#SendEmail').val(true); return true" />
<input type="submit" value="Save As Draft"
       onclick="$('#SendEmail').val(false); return true;" />

Controller Action

public ActionResult SendEmail(FooViewModel model)
{
   if(model.SendEmail)
   {
      //Send Email
   }
   else
   {
      //Save as draft
   }
   return RedirectToAction("SendEmailSuccess");
}

work around: use javascript for submiting the form instead of submit buttons
