传递嵌套复杂的JSON到MVC控制器 [英] Passing NESTED Complex json to MVC Controllers

问题描述

注意：这可能是促使一些，以纪念这是一个已经回答的问题，但它不是，我一直在寻找的答案相当长一段时间。这是<一个修改后的版本href="http://stackoverflow.com/questions/24027245/mvc-any-version-pass-nested-complex-json-object-to-controllers">MVC （所有版本） - 传递复杂的嵌套JSON对象控制器的，这也没有得到回答。

NOTE: It might be urging for some to mark this as an already answered question BUT it is not, I have been searching for an answer for quite a while. This is a modified version of "MVC (Any Version) - Pass Nested Complex JSON object to Controllers", which also has not been answered.

问题：是否有可能通过后jQuery的Ajax调用的JSON数据到一个MVC控制器，你逝去的数据是一个复杂类型更复杂的类型呢？实施例数组的数组

Question: Is it possible to post a JSON data through jQuery ajax call to a MVC Controller where the data you are passing is a complex type with more complex types in it? Example an array of arrays.

var arrayOfarrays = [];
var simpleArray = [];

simpleArray[simpleArray.length] = simpleArray.length + 1;
simpleArray[simpleArray.length] = simpleArray.length + 1;
simpleArray[simpleArray.length] = simpleArray.length + 1;
simpleArray[simpleArray.length] = simpleArray.length + 1;
simpleArray[simpleArray.length] = simpleArray.length + 1;

arrayOfarrays[arrayOfarrays.length] = simpleArray;
arrayOfarrays[arrayOfarrays.length] = simpleArray;
arrayOfarrays[arrayOfarrays.length] = simpleArray;
arrayOfarrays[arrayOfarrays.length] = simpleArray;
arrayOfarrays[arrayOfarrays.length] = simpleArray;

以上是我的数据。正如你看到的，一个 simpleArray 是一个单纯的阵列和 arrayOfarrays 是一个数组的数组这是一个方式嵌套的复杂类型

The above is my data. As you see, a simpleArray is a mere array and the arrayOfarrays is an array of arrays which is in a way a nested complex type

$.ajax({
    url: '/Home/Save',
    data: {arrayData:simpleArray, arrayOfarrayData:arrayOfarrays},
    type: 'POST',
    dataType: 'json',
    traditional:true,
    cache: false,
    success: function (result) {
    }
});

以上片段是我的jQuery Ajax调用控制器 /主页/保存这里下面是控制器本身。请注意，我试图使用和不使用传统：真正的选项

The above snippet is my jQuery ajax call to the controller /Home/Save and here below is the controller itself. Note that I have tried with and without the traditional:true option.

[HttpPost]
public JsonResult Save(int[] arrayData, int[][] arrayOfarrayData)
{
    return Json("received");
}

这是我所观察到的：

• 使用传统：真正的我收到 arrayData 这是一个简单的数组的 /主页/保存控制器，但 arrayOfarrayData 是空
• 没有传统：真正的我接受 arrayData 为空但 arrayOfarrayData 被接收为5个元素的数组，但该元素不是子阵列信息，你会期望，但其空

• With traditional:true I receive the arrayData which is a simple array in the /Home/Save controller but the arrayOfarrayData is empty
• Without traditional:true I receive arrayData as null but arrayOfarrayData is received as an array of 5 elements but the elements are not the sub-array information you would expect but its empty

<强> PS：阵列的阵列仅仅是一个例子，不NESTED复杂类型似乎工作。或者有没有解决这个办法吗？

PS: An array of array is only an example, no NESTED complex type seem to work. Or is there any way around this?

推荐答案

我想你需要字符串化您的数据。

I think you need to stringified your data

var dataToSend={
          'arrayData':simpleArray, 
          'arrayOfarrayData':arrayOfarrays
};

$.ajax({
    url: '/Home/Save',
    data: JSON.stringify(dataToSend),
    type: 'POST',
    contentType: 'application/json',
    dataType: 'json',
    traditional:true,
    cache: false,
    success: function (result) {
    }
});
