jQuery的岗位阵列 - ASP.Net MVC 4 [英] jQuery post array - ASP.Net MVC 4

问题描述

我已经花了8个小时左右今天试图弄清楚这一点。我已经看到很多的解决方案，但不能得到相同的结果。我有它的一切做是比较新的ASP.Net预感。

I have spent 8 hours or so today trying to figure this out. I have viewed lots of solutions but cannot get the same results. I have a hunch it has everything to do with being relatively new to ASP.Net.

下面是我试过，没有运气模仿的最新问题。
=>张贴数组作为JSON到MVC控制器

Here is the latest question I tried mimicking with no luck. =">Post Array as JSON to MVC Controller

<一个href=\"http://stackoverflow.com/questions/320291/how-to-post-an-array-of-complex-objects-with-json-jquery-to-asp-net-mvc-control\">How发布使用JSON，jQuery的复杂对象的数组ASP.NET MVC控制器？

问题的基本流程：
我有JSON对象的数组，我想传递给我的控制器。当我通过它显示的数据可以说，例如3个项目，但它们的值不通过或它只是显示没有获得通过。萤火虫显示它通过它，所以我认为东西是不正确的设置和它不允许它正确地设置该变量了C＃的一面。

Basic Rundown of Problem: I have an array of json objects I would like to pass to my controller. When I pass the data it shows lets say for example 3 items, but their values are not passed or it just shows nothing was passed. Firebug shows it passed it so I assume that something is not setup right and its not allowing it to set that variable up correctly on the C# side.

我已经尝试了一些东西，生病一一列举如下：
设置1：
我试图嘲弄我的第二个链接看到：

I have tried a few things and ill list them below: Setup 1: I tried mocking what I seen at the second link:

$.ajax({
        type: 'Post',
        cache: false,
        url: '/Workflow/Home/UpdateStepPositions',
        data: { 'steps': ['1','2','3'] },
        async: false,
        success: function (data) {
            console.debug(data);
        },
        error: function (data) {
            console.debug(data);
        }
    });

 Controller
 [HttpPost]
    public ActionResult UpdateStepPositions(string[] steps){

        var bresults = new {
            Success = false,
            Message = "Unable to update step positions."
        };

        return Json(bresults);
    }

我甚至不能得到简单的设置工作。它获得的功能和显示没有什么通过....

I couldn't even get that simple setup working.. It gets to the function and shows there was nothing passed....

设置2：

 list = new Array();
    list.push({ "step": 1, "position": 1 });
    list.push({ "step": 2, "position": 2 });
    list.push({ "step": 3, "position": 3 });

    $.ajax({
        type: 'Post',
        cache: false,
        url: '/Workflow/Home/UpdateStepPositions',
        data: JSON.stringify({ 'steps': list }),
        async: false,
        success: function (data) {
            console.debug(data);
        },
        error: function (data) {
            console.debug(data);
        }
    });

    Controller
   [HttpPost]
    public ActionResult UpdateStepPositions(List<UpdatedSteps> steps){
        var bresults = new {
            Success = false,
            Message = "Unable to update step positions."
        };

        return Json(bresults);
    }

   Class
   public class UpdatedSteps {
    public string Step { get; set; }
    public string Position { get; set; }
}

任何人都可以照到什么，我丢失或点我在正确的方向轻一些？希望它的东西简单，只是一个新手的错误！

Can anyone shine some light on what I'm missing or point me in the right direction? Hopefully its something simple and just a newbie mistake!

推荐答案

MVC检测到它的contentType所接收的数据类型。在这里工作的例子：

MVC detects what type of data it receive by contentType. Here is working example:

$(function () {
    $.ajax({
        type: 'Post',
        dataType: 'json',
        url: '/Workflow/Home/UpdateStepPositions',
        data: JSON.stringify({ steps: ['1', '2', '3'] }),
        contentType: 'application/json; charset=utf-8',
        async: false,
        success: function (data) {
            console.debug(data);
        },
        error: function (data) {
            console.debug(data);
        }
    });
});

现在一切OK与要求：

Content-Type:        application/json; charset=utf-8
X-Requested-With:    XMLHttpRequest

和响应：

Content-Type:        application/json; charset=utf-8
