ASP.NET Core-将Enum参数从razor View传递给formaction [英] ASP.NET Core - pass enum parameter from razor View to formaction

问题描述

我们的团队继承了我们正在努力改进的系统.

Our team has inherited a system that we're trying to improve as we go along.

在剃刀视图中我们注意到的一件事是，许多情况下编写了不同的控制器动作，看起来它们可以被参数化.

One thing we've noticed in our razor Views is many cases where different Controller Actions are written, that look like they could be parameterised.

例如，我们有点像这样...

for example, we have something a bit like this...

ProcessSubmissionView.cshtml

<button class="btn" type="submit" id="process-english-submission" formaction="ProcessWelshSubmission" formmethod="post">Process Welsh Submission</button>

<button class="btn" type="submit" id="process-welsh-submission" formaction="ProcessEnglishSubmission" formmethod="post">Process English Submission</button>

...我们更喜欢这样写，即调用一个动作( ProcessSubmission )，但是要有一个参数-在这种情况下，是一个'Nationality'枚举:

...that we'd prefer to write like this, i.e. call a single action (ProcessSubmission), but with a parameter - in this case, a 'Nationality' enum:

<button class="btn" type="submit" id="process-english-submission" formaction="ProcessSubmission" TODO PARAM= Nationality.English formmethod="post">Process English Submission</button>

<button class="btn" type="submit" id="process-welsh-submission" formaction="ProcessSubmission" TODO PARAM= Nationality.Welsh formmethod="post">Process Welsh Submission</button>

鉴于我们有一个 Nationality 枚举，我们应该在上面所说的 TODO PARAM = Nationality.English/Welsh 的那部分输入什么?

Given we have a Nationality enum, what should we put in the part above where it says TODO PARAM= Nationality.English/Welsh?

推荐答案

您可以在< button type ="submit"上使用 name 和 value 属性"> .

You can use the name and value attrbutes on <button type="submit">.

<button type="submit" name="@Html.NameFor( m => m.Nationality )" value="@( nameof(MyEnum.English) )">english</button>
