JQuery的Ajax和ASP.NET MVC3导致空参数 [英] JQuery Ajax and ASP.NET MVC3 causing null parameters

问题描述

这个问题已经被问过很多次，但我没有找到解决方案，似乎工作。让我觉得这可能是一个新的问题，也许一些具体的事情到ASP.NET MVC 3。

This question has been asked many times but none of the solutions I found seem to be working. Makes me think this could be a new issue, and maybe something specific to ASP.NET MVC 3.

我使用JQuery Ajax来作出一个ASP.NET MVC 3控制器的简单调用。像这样

I am using JQuery Ajax to make a simple call to an ASP.NET MVC 3 controller. Like so

var addressInfo = { 
    Address1: "423 Judy Road",
    Address2: "1001",
    City: "New York",
    State: "NY",
    ZipCode: "10301",
    Country: "USA" 
};

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: JSON.stringify(addressInfo),
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',
    success: function () {
        alert("success");
    },
    error: function () {
        alert("error");
    }
});

控制器看起来像这样

The controller looks like this

[HttpPost]
public ActionResult Check(AddressInfo addressInfo)
{
    // Do something and return Json(something)
}

这是不行的，但它应该基于Scottgu的的JavaScript和AJAX技术的改进一节<一href="http://weblogs.asp.net/scottgu/archive/2010/07/27/introducing-asp-net-mvc-3-$p$pview-1.aspx">post

This does not work, though it should have based on the "JavaScript and AJAX Improvements" section of Scottgu's post

我已经试过这许多不同的变化，例如：

I have tried many different variations of this, for example:

var args = new Object();
args.addressInfo = { 
    Address1: "423 Judy Road",
    Address2: "1001",
    City: "New York",
    State: "NY",
    ZipCode: "10301",
    Country: "USA" 
};

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: JSON.stringify(args),
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',
    success: function () {
        alert("success");
    },
    error: function () {
        alert("error");
    }
});

然后两个以上直接与JSON对象的：

And then both of the above directly with the JSON object:

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: args,
    success: function () {
        alert("success");
    },
    error: function () {
        alert("error");
    }
});

无工作。如果我只有我传递给控制器​​的字符串，该工程。但只要我介绍对象，我不能让它的工作。

None work. If I only have a string that I pass to the controller, that works. But as soon as I introduce an object, I cannot get it to work.

任何人都知道可能是什么问题。

Anyone know what might be the issue.

非常感谢寻找到这！

推荐答案

您code似乎不错，它应该工作。我刚刚测试了以下在一个新的应用程序没有问题。

Your code seems fine and it should work. I've just tested the following in a new application without problems.

型号：

public class AddressInfo 
{
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
    public string Country { get; set; }
}

控制器：

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Check(AddressInfo addressInfo)
    {
        return Json(new { success = true });
    }
}

查看：

<script type="text/javascript">
    var ai = {
        Address1: "423 Judy Road",
        Address2: "1001",
        City: "New York",
        State: "NY",
        ZipCode: "10301",
        Country: "USA"
    };

    $.ajax({
        url: '/home/check',
        type: 'POST',
        data: JSON.stringify(ai),
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            alert(data.success);
        },
        error: function () {
            alert("error");
        }
    });
</script>
