多个提交按钮与从按钮传递的值

Question

我构建表单的方式是有多个“测试连接”提交按钮和一个“保存”提交按钮，以保存每个测试连接的所有凭据和URL。我看到了一些建议的解决方案，但我不想做一个Ajax或JavaScript。所以我想知道这是否可能。顺便说一下，我想通过提交按钮将值作为枚举值传递给控制器​​，并在控制器中接收该枚举。

我可以很容易地做出多个ActionResults，但它对我来说只是感觉如此复杂，如果我必须改变测试连接中的某些东西，我将不得不改变所有。所以我想在同一个表单中只有一个TestConnection的ActionResult方法和一个Save ActionResult。

当我点击保存按钮时，所有凭证都将作为ApplicationSettings模型发送到控制器。

当我单击测试连接按钮时，我仍然收到ApplicationSettings模型加上DatabaseSystems枚举，并根据接收到的按钮的枚举，我会做必要的连接。

下面是代码片段，但我不能让它们工作。

尝试的方法： 1.空白表单动作，提交按钮的名称相应地为“Save”和“TestConnection”。 - 保存作品。 TestConnection不起作用说无法找到资源。 2.表单操作指向“TestConnection”，TestConnection按钮名称设置为 “database”，值设置为@ DatabaseSystems.xxx，Save按钮设置为“action：Save”，添加Action的ActionResult方法[MultipleButton(Name = "action", Argument = "Save")] - TestConnection工作，保存不起作用的含糊不清的要求。

我似乎无法弄清楚配置，使他们都工作。 :(

控制器

[HttpPost]

    // depending on the DatabaseSystems enum passed, then I'll do the necessary connection check.

ActionResult Save(ApplicationSettings model)

    public string con3_pw { get; set; } 
    public string con3_url { get; set; } 

    ... and many more systems

恩UM与多个不同的参数

public enum DatabaseSystems 
{ 
    System1, 
    System2, 
    System3, 
    ... and many more systems 
} 

Answer 1

终于明白了。虽然@Stephen Muecke并没有真正提供直接的解决方案，但我应该说他让我重新考虑再次使用形式，所以我仍然要感谢他。谢了哥们！下面是我如何解决它：

查看

@using Models.Enums 
@model MyApp.Data.ApplicationSettings 

@Html.AntiForgeryToken() 
@using (Html.BeginForm()) 
{ 
    ... 
    <button type="submit" class="btn btn-warning pull-right" name="database" value="@DatabaseSystems.System1" formaction="Admin/TestConnection" data-toggle="collapse" data-target="#loading"><span class="glyphicon glyphicon-link"></span> Test Connection</button> 
    ... 
    <button type="submit" class="btn btn-warning pull-right" name="database" value="@DatabaseSystems.System2" formaction="Admin/TestConnection" data-toggle="collapse" data-target="#loading"><span class="glyphicon glyphicon-link"></span> Test Connection</button> 
} 

控制器

public ActionResult TestConnection(ApplicationSettings model, DatabaseSystems database) 
{ 
    // at the end, instead of putting return View() or return("Index", model), I used below code 
    return Redirect("/[ControllerName]"); 
{ 

......这样一来，formaction会做的ActionResult方法的调用对我来说，同时保持该按钮的name属性可用于其他用途，例如将其作为参数传递给我的TestConnection方法。

Answer 2

使用单一的动作名称提交给button.and的名字是在这两个按钮相同，但其值不同

进行检查connectin

<button type="submit" class="btn btn-warning pull-right" name="save" value="@DatabaseSystems.System3" data-toggle="collapse" data-target="#loading"><span class="glyphicon glyphicon-link"></span> Test Connection</button> 

用于保存

<button type="submit" class="btn btn-warning pull-right" name="Save" value="save" data-toggle="collapse" data-target="#loading"><span class="glyphicon glyphicon-link"></span> Save</button> 


    [HttpPost] 
    ActionResult Save(ApplicationSettings model,string Save) 
       { 
    if(Save=="Testconnection") 
    { 
    //do your code on save 
    } 
    if(save="Save") 
    { 
    //do your code on save 
    } 
     }
