将javascript对象中的数组传递给mvc控制器

问题描述

我有一个像这样的javascript对象:

I have a javascript object like:

var data={
 Manager:name,
 ID:id,
 EmployeeNames:arrayEmployees
};

如您所见，name和id是简单的字符串，而EmployeeNames是一个数组对象.我有这样的ajax呼叫:

As you can see, name and id are simple strings but EmployeeNames is an array object. I have the ajax call like this:

 $.ajax({
      type: "POST",
      url: "GetManagerEmployees",
      content: "application/json;",
      dataType: "json",
      data: data,
      success:
      error:
});

在控制器中，我有一个方法GetManagerEmployees(Data data)，其参数类型为Data，其中包含所有属性:

In the controller I have a method GetManagerEmployees(Data data) with parameter of type Data which contains all the properties:

public class Data
{
    public string Manager { get; set; }
    public int id { get; set; }
    public List<string> EmployeeNames { get; set; }

我在控制器中获取data.EmployeeNames为null，这是怎么回事?你能帮我吗?

I'm getting data.EmployeeNames as null in my controller, what am I doing wrong here? Can you please help me on this?

推荐答案

仅使用此结构创建了一个项目，并且可以正常工作:

Just created a project with this structure and It's working:

请注意，jquery ajax调用上的radius:true:

Note that traditional:true on the jquery ajax call:

此外，您不需要列表.只需在模型中使用简单的字符串数组即可.

Also, you don't need a List for that. Just use a simple string array in your model.

JavaScript

$("#myBtn").click(function () {

                var arrayEmployees = new Array();

                arrayEmployees.push("Name1");

                var data = {
                    "Manager": 'John',
                    "id": 1,
                    "EmployeeNames": arrayEmployees
                };

                $.ajax({
                    type: "POST",
                    traditional:true,
                    url: "PostManager",
                    content: "application/json;",
                    dataType: "json",
                    data: data,
                    success: function () {
                    }
                });
            });

控制器/型号

[HttpPost]
public void PostManager(Data  data)
{

}

public class Data
{
    public string Manager { get; set; }
    public int id { get; set; }
    public string[] EmployeeNames { get; set; }
}
