Question

我构建表单的方式是有多个“测试连接”提交按钮和“保存”提交按钮，以保存每个测试连接的所有凭据和URL。我见过一些建议的解决方案，但我不想做ajax或javascript。所以我想知道这是否可行。顺便说一句，我想通过提交按钮将值传递给控制器作为枚举值，并在我的控制器中接收枚举。

我可以很容易地制作多个ActionResults，但它对我来说感觉很复杂，如果我必须在测试连接中改变一些东西，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。

单击“保存”按钮时，所有凭据都将作为ApplicationSettings模型发送到控制器。

当我单击Test Connection按钮时，我仍然会收到ApplicationSettings模型和DatabaseSystems枚举，并且根据从按钮收到的枚举，我会进行必要的连接。

以下是代码段，但我无法让它们正常工作。

尝试过的方法： 1.空白表单操作，提交按钮的名称为“保存”和“TestConnection”。 - 保存工作。 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”，同时值设置为@ DatabaseSystems.xxx，Save按钮设置为“action：Save”，ActionResult方法为Save添加[MultipleButton(Name = "action", Argument = "Save")] - TestConnection工作，Save不起作用说不明确的请求。

我似乎无法弄清楚配置是否同时起作用。：（

Answer 1

对多个提交按钮使用具有不同参数的单个动作名称。并且两个按钮中的名称相同但值不同

用于检查连接

<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
     }
      }

Answer 2

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编队，所以我还是要感谢他。谢了哥们！以下是我如何解决它：

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> }

<强>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，formaction将为我调用ActionResult方法，同时保持按钮的name属性可用于其他目的，例如将其作为参数传递给我的TestConnection方法。

多个提交按钮，其值从按钮
