嵌套的对象在MVC ajax形式捕捉在控制器

本文关键字:控制器 ajax 对象 MVC 嵌套 | 更新日期: 2023-09-27 18:07:10

In MVC3 Razor:

我试图创建一个表单,动态地,使用多个对象的字段。但是由于某些原因,我在控制器中获得的数据不包含输入值。

FormViewModel.cs

    namespace DynamicForm.Models
    {
        public class FormViewModel
        {
            public Name name = new Name();
            public Address address = new Address();
            public FormViewModel()
            {
            }
        }
public class Name
    {
        [Required()]
        public String first { get; set; }
        [Required()]
        public String last { get; set; }
        public Name()
        {
            first = "";
            last = "";
        }
    }
    public class Address
    {
        public String street1 { get; set; }
        public String street2 { get; set; }
        public Address()
        {
            street1 = "";
            street2 = "";
        }
    }
    }

FormController.cs

[HttpPost()]
        public ActionResult Save(FormViewModel toSave)
        {
            return View();
        }

index.cshtml:

@using DynamicForm;
@using DynamicForm.Models;
@model FormViewModel
@{
    ViewBag.Title = "Form";
}
<h2>Form</h2>
    @using (Html.BeginForm("Save", "Form"))
    { 
        @Html.TextBoxFor(m => m.address.street1)
        @Html.TextBoxFor(m => m.address.street2)
        @Html.TextBoxFor(m => m.name.first)
        @Html.TextBoxFor(m => m.name.last)
        <input type="submit" value="Send" /> 
    }

关于为什么数据没有被填充到FormViewModel对象中的任何想法?

在FormViewModel中,name和address应该是属性。默认的模型绑定器只作用于属性。

public class FormViewModel
{
    public Name Name {get;set;}
    public Address Address {get;set;}
}
