ASP.NET MVC 3 Razor: Passing Data from View to Controller
提问by Kyle M
I'm brand new to all things .NET. I have a very basic web page with an HTML form. I want 'onsubmit' to send the form data from the View to the Controller. I've seen similar posts to this but none have answers involving the new-ish Razor syntax. What do I do with 'onsubmit', and how do I access the data from the Controller? Thanks!!
我对 .NET 的所有事物都是全新的。我有一个带有 HTML 表单的非常基本的网页。我希望“onsubmit”将表单数据从视图发送到控制器。我看过类似的帖子，但没有一个涉及新式 Razor 语法的答案。我如何处理“onsubmit”，以及如何从 Controller 访问数据？谢谢！！

You can wrap your view controls you want to pass in Html.Beginform.
您可以将要传递的视图控件包装在 Html.Beginform 中。
For example:
例如：
@using (Html.BeginForm("ActionMethodName","ControllerName"))
{
... your input, labels, textboxes and other html controls go here
<input class="button" id="submit" type="submit" value="Submit" />
}
When Submit button is pressed everything inside of of that Beginform will be submitted to your "ActionMethodName" method of the "ControllerName" controller.
当按下提交按钮时，Beginform 内部的所有内容都将提交给“ControllerName”控制器的“ActionMethodName”方法。
ON the controller side you can access all received data from the view like this:
在控制器端，您可以像这样从视图中访问所有接收到的数据：
public ActionResult ActionMethodName(FormCollection collection)
{
string userName = collection.Get("username-input");
}
collection object above will contain all your input entries that we submitted from the form. You can access them by name just like you would access any array: collection["blah"] or collection.Get("blah")
上面的集合对象将包含我们从表单提交的所有输入条目。您可以像访问任何数组一样按名称访问它们： collection["blah"] 或 collection.Get("blah")
You can also pass parameters to your controllers directly without sending the entire page with FormCollection:
您还可以直接将参数传递给您的控制器，而无需使用 FormCollection 发送整个页面：
@using (Html.BeginForm("ActionMethodName","ControllerName",new {id = param1, name = param2}))
{
... your input, labels, textboxes and other html controls go here
<input class="button" id="submit" type="submit" value="Submit" />
}
public ActionResult ActionMethodName(string id,string name)
{
string myId = id;
string myName = name;
}
Or you can combine both of these methods and pass specific parameters along with the Formcollection. It's up to you.
或者，您可以将这两种方法结合起来，并与 Formcollection 一起传递特定参数。由你决定。
Hope it helps.

Defining a form in the following way:
通过以下方式定义表单：
@using (Html.BeginForm("ControllerMethod", "ControllerName", FormMethod.Post))
@using (Html.BeginForm("ControllerMethod", "ControllerName", FormMethod.Post))
Will make a call to the method "ControllerMethod" in the controller "ControllerName". In the method you can accept a model, or other data types as inputs. See thistutorial for examples using forms and razor mvc.
将调用控制器“ControllerName”中的方法“ControllerMethod”。在该方法中，您可以接受模型或其他数据类型作为输入。有关使用表单和 razor mvc 的示例，请参阅本教程。
