我的工作与ASP.NET-MVC。我尝试发布在阿贾克斯的数组,但我不知道如何得到它在我的控制器。这是我的code:

I work with ASP.NET-MVC. I try to post an array in ajax but I don't know how to get it in my controller. Here is my code :

阿贾克斯

var lines = new Array();
lines.push("ABC");
lines.push("DEF");
lines.push("GHI");
$.ajax(
{
    url: 'MyController/MyAction/',
    type: 'POST',
    data: { 'lines': lines },
    dataType: 'json',
    async: false,
    success: function (data) {
        console.log(data);
    }
});

myController的

MyController

public JsonResult MyAction(string[] lines)
{
    Console.WriteLine(lines); // Display nothing
    return Json(new { data = 0 });
}

为什么我看不到我的台词?如何正确发布此数组,并用它在MyAction的?

Why I can't see my lines ? How to properly post this array and use it in MyAction ?

推荐答案

设置的contentType:应用/ JSON的选项, JSON.stringify 的参数:

var lines = new Array();
lines.push("ABC");
lines.push("DEF");
lines.push("GHI");
$.ajax(
{
    url: 'MyController/MyAction/',
    type: 'POST',
    data: JSON.stringify({ 'lines': lines }),
    dataType: 'json',
    contentType: 'application/json',
    async: false,
    success: function (data) {
        console.log(data);
    }
});

您还可以设置你得到,如果它是有道理的商业案例对象的类型。例如:

You can also set the type of objects you're getting if it makes sense in your business case. Example:

public JsonResult MyAction(string[] lines)
{
    Console.WriteLine(lines); // Display nothing
    return Json(new { data = 0 });
}

和,一些比较实用与您所发送的内容:

And, something more practical with what you're sending in:

public class MyModel {
    string[] lines;
}

最后:

public JsonResult MyAction(MyModel request)
{
    Console.WriteLine(string.Join(", ", request.lines)); // Display nothing
    return Json(new { data = 0 });
}
