如何在ASP.NET MVC页面上动态显示字段列表并将输入值传递回后端？

Question

I have a scenario which requires the admin user to identify a number of parameters at the back end and let end user to input value for these parameters, sending back.

I am wondering is there any solution to this kind of scenario? My guess, java script would be required.

Thank you.

You need to make a HTML Form. A form will be rendered to the user, and when the user submits the form, the entered information will be sent back to the server.

This page is a decent tutorial on how to make a HTML form using ASP.NET MVC.

You have to create a model (class) with the properties you want the user to submit.

public class MyModel
{
    public Int32 RandomNumber { get; set; }
}

Then, you will create two MVC actions. One, for requesting the form page, which will return a ViewResult with an empty model. The other will be the submit action, and will require a parameter with the model. This will be sent via the user's submission of the form:

public class FooController : Controller
{
    [HttpGet]
    public void Create()
    {
        return this.View("~/Views/FooController/Create.cshtml", new MyModel() );
    }
    [HttpGet]
    public void Create(MyModel model)
    {
        //Do something with model information, such as save to database
    }
}

The ViewResult will need to return a CSHTML page that creates a form for this model.

@model MyModel

@using(Html.BeginForm("Create", "Foo", FormMethod.Post))
{
    @Html.TextBoxFor( m => m.RandomNumber )
}
