将复杂的 JSON 映射到 MVC Action 参数中的列表

发布于 2024-11-01 04:05:19 字数 799 浏览 1 评论 0原文

我有这样的类

public class someList
{
   public string strOne {get; set;}
   public string strTwo {get; set;}
}
public class Entity
{
    public string EntityMember;
    public List<someList> entityList;
}

然后我有一个控制器和操作，

public ActionResult MyControllerAction(Entity objEntity)

如何使用 JSON 数据从浏览器发布表单，以便它与我的实体对象映射。这是我当前用于提交表单的 javascript 函数，

function submitForm() {
    var Entity = {};
    var eList= new Array();

    eList[0] = { strOne: "91", strTwo: "12" };
    eList[1] = { strOne: "92", strTwo: "12" };

    Entity = { EntityMember: "Member Value", entityList: eList };
    $.post("/MyController/MyControllerAction", Entity);
}

但它不起作用。我能够获取 EntityMember 的值，但无法获取 List 对象。

有什么想法吗？

I have classes like this

public class someList
{
   public string strOne {get; set;}
   public string strTwo {get; set;}
}
public class Entity
{
    public string EntityMember;
    public List<someList> entityList;
}

Then I have a controller and action,

public ActionResult MyControllerAction(Entity objEntity)

How to post the form from browser with JSON data so that it maps with my Entity object. Here is my currenct javascript function for submitting the form,

function submitForm() {
    var Entity = {};
    var eList= new Array();

    eList[0] = { strOne: "91", strTwo: "12" };
    eList[1] = { strOne: "92", strTwo: "12" };

    Entity = { EntityMember: "Member Value", entityList: eList };
    $.post("/MyController/MyControllerAction", Entity);
}

But it is not working. I am able to get the value of EntityMember but the List object does not come.

Any ideas?

如果这是针对 asp.net mvc 3，则需要对实体进行 stringfied

$.ajax({                                                    
        url: "/MyController/MyControllerAction",                                       
        type: "POST",                                           
        data: JSON.stringify(Entity),                          
        dataType: "json",                                       
        contentType: "application/json; charset=utf-8",         
        success: function (data) {                              
            ....                                     
        }                                                       
    });

如果这是针对 asp.net mvc 2，您还需要注册 json 提供程序，请参考此 link

你的不起作用的原因是jquery 的内置序列化格式已更改 http://api.jquery.com/jQuery.param/

您需要将其设置为使用传统方式：

jQuery.ajaxSettings.traditional = true;

或使用不同的序列化方法。（在上面，我使用 stringify 函数进行 JSON 绑定，这是 JSON.org 的 json2.js 的一部分）

if this is for asp.net mvc 3, entity needs to be stringfied

$.ajax({                                                    
        url: "/MyController/MyControllerAction",                                       
        type: "POST",                                           
        data: JSON.stringify(Entity),                          
        dataType: "json",                                       
        contentType: "application/json; charset=utf-8",         
        success: function (data) {                              
            ....                                     
        }                                                       
    });

if this is for asp.net mvc 2, you will also need to register the json provider, please reference this link

The reason yours doesn't work is that jquery's built-in serialization format has been changed http://api.jquery.com/jQuery.param/

you will need to either set it to use traditional way:

jQuery.ajaxSettings.traditional = true;

or use a different serialization method. (In above, I used stringify function for JSON binding, part of JSON.org's json2.js)
