how to use multiple submit button in mvc with c#.

推荐答案

尝试一下.您可以通过将name属性设置为所有提交按钮相同来获取button的值

Try this. You can take the value of button by setting the name attribute as same to all the submit button

@using (Html.BeginForm("Create", "Home", FormMethod.Post, new { id = "submitForm" }))
{
@Html.TextBoxFor(m => m.Name, new { maxlength = 50 })

 <button type="submit" id="btnSave" name="command" value="Save">Save</button>
 <button type="submit" id="btnSubmit" name="command" value="Cancel"/>
}

public ActionResult Create(YourModel obj,string command)
{

//from here you can get the value of button you click
if(command="Save")
{

}
else if(command=="Cancel")
{
}
else
{
return RedirecToAction("Index");
}
return View();

}

1)肮脏的一个

1) Dirty one

<input type="submit" id="Submit1" name="btnSubmit", value="action:First" />
<input type="submit" id="Submit2" name="btnSubmit", value="action:Second" />

[HttpPost]
public ActionResult MyAction(string btnSubmit, MyFormModel model)
{
  switch (btnSubmit) {
    case "action:First":
      /* Your code */
      break;
    case "action:Second":
      /* Your code */
      break;
  }

2)更好-将上面的代码重构为attribute

2) Nicer - refactor code above to attribute
Like idea from
http://blog.maartenballiauw.be/post/2009/11/26/Supporting-multiple-submit-buttons-on-an-ASPNET-MVC-view.aspx[^]

Rephrasing code in article above:

    [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)
    {
        bool isValidName = false;
        string 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;
    }
}

和您的代码

and your code

[HttpPost]
 [MultipleButton(Name = "action", Argument = "First")]
 public ActionResult First(MyFormModel model) { ... }

 [HttpPost]
 [MultipleButton(Name = "action", Argument = "Second")]
 public ActionResult Second(MyFormModel model) { ... }
