c# - 两种形式和一种视图模型

Question

我在一页中有两个表格。两者都有自己的属性和提交操作，但在两种表单中都有一些共同的属性。

有没有办法使用一个视图模型来构建具有两个表单的视图，该视图模型与视图中的两个表单共享属性？

实际上我有重复的字段，我必须使用 jquery 复制两个字段中值的更改。

谢谢。

Answer 1

you can use HtmlPrefix to achieve this.

1. I have created a model as

   public class TestModel
   {
     [Required]
     public int Id { get; set; }
     [Required]
     public string Name { get; set; }
   }
   

2. In Controller we need to have one GetMethod but two post method for each form, but with different BindPrefix

   public ActionResult TestLoad()
   {
       TestModel model = new TestModel();
       return View(model);
   }
   
   public ActionResult TestA([Bind(Prefix = "A")]TestModel model)
   {
       return View("TestLoad",model);
   }
   public ActionResult TestB([Bind(Prefix="B")]TestModel model)
   {
       return View("TestLoad",model);
   }
   

   3. In the view. Here also we need to Specify binding prefix

   <table>
    <tr>
     <td>
       @{Html.ViewData.TemplateInfo.HtmlFieldPrefix="A";}
       @{Html.RenderPartial("PartialA");}
     </td>
     <td>
       @{Html.ViewData.TemplateInfo.HtmlFieldPrefix="B";}
       @{Html.RenderPartial("PartialB");}
     </td>
   </tr>
   </table>
   

   4. Both partial view are exactly same , except that they post data to different actions (as defined in controller)

   5. Now if you run the project you should get appropriate output.
