以JSON（无AJAX）的形式提交表单

Is it possible to submit form data as JSON, without using AJAX?

是否可以在不使用AJAX的情况下以JSON形式提交表单数据？

I've tried changing the enctype:

我试过更改enctype：

<form enctype="application/json"></form>

But that's not a valid value according on w3schools

但根据w3schools，这不是一个有效的价值

The reason I would like this behaviour is that the requested URL will return a file, which I obviously can't do anything with if I use AJAX. I would like to send JSON data marked as Content-Type: application/json so that ASP.NET MVC will use its JSON binding.

我想要这种行为的原因是请求的URL将返回一个文件，如果我使用AJAX，我显然无法做任何事情。我想发送标记为Content-Type：application / json的JSON数据，以便ASP.NET MVC将使用其JSON绑定。

Yes, you can serialize form like an object with plugin. I write a sample for you;

是的，您可以使用插件将表单序列化为对象。我为你写了一个样本;

//Head

//头

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="jquery.serialize-object.js"></script>

You can download plugin from here

你可以从这里下载插件

//Form

//形成

<form id="frm">
<input type="text" name="Model[Firstname]">
<input type="text" name="Model[Lastname]">
<input type="text" name="ModelDetail[PhoneNumber]">
...
<button type="button" onclick="sendForm()">Send</button>
</form>

//JS

// JS

function sendForm(){
model_data = $("#frm").serializeObject();
$.ajax({
url: 'YOUR_SERVICE_URL',
type: 'POST',
contentType: 'application/json',
data: JSON.stringify(model_data),
dataType: 'json',
success:function(e){
    // I know, you do not want Ajax, if you callback to page, you can refresh page here
   }
});

Good luck!

祝你好运！

Could you use JSON.stringify() to serialize your client side object and then stuff that into a hidden input and submit your form...and then in the controller side pull it back out of the Request.Form and deserialize it into your object?

您可以使用JSON.stringify（）来序列化您的客户端对象，然后将其填充到隐藏的输入中并提交您的表单...然后在控制器端将其拉出Request.Form并将其反序列化为您的对象？

[Edit] Just saw in the comment section underneath of the original question that this was essentially a duplicate post and that this * worked as a solution.

you can try;

你可以试试;

// html

<form type="POST" action="/Home/Test">
<input id="foo" value="hede">
</form>

// dto

public class TestInDto{
 public string foo {get;set;}
}

// home controller

//家庭控制器

[HttpPost]
void Test(TestInDto inDto){
 var foo = inDto.foo;

}

As per W3C standards you can't pass the data like JSON using

根据W3C标准，您无法使用JSON等数据传递

<form enctype="application/json"></form>

Description

描述

User agents that implement this specification will transmit JSON data from their forms whenever the form's enctype attribute is set to application/json. During the transition period, user agents that do not support this encoding will fall back to using application/x-www-form-urlencoded. This can be detected on the server side, and the conversion algorithm described in this specification can be used to convert such data to JSON.

只要表单的enctype属性设置为application / json，实现此规范的用户代理就会从其表单传输JSON数据。在过渡期间，不支持此编码的用户代理将回退到使用application / x-www-form-urlencoded。这可以在服务器端检测到，并且本规范中描述的转换算法可用于将这些数据转换为JSON。

The path format used in input names is straightforward. To begin with, when no structuring information is present, the information will simply be captured as keys in a JSON object

输入名称中使用的路径格式很简单。首先，当没有结构化信息时，信息将被简单地捕获为JSON对象中的键

You can send the request by AJAX and then generate a file downloading URL in the controller and send it back in the AJAX response. Then you can just open up that URL in another window. This would be a complete AJAX-based solution so you can use JSON.

您可以通过AJAX发送请求，然后在控制器中生成文件下载URL并将其发送回AJAX响应中。然后，您可以在另一个窗口中打开该URL。这将是一个完整的基于AJAX的解决方案，因此您可以使用JSON。

Try this simple store your POST array in variable and then encode it as json obj. like this-->

尝试将这个简单的POST数组存储在变量中，然后将其编码为json obj。像这样 - >

$postarray=($_POST);
$jsondata=json_encode($postarray);

$ postarray =（$ _ POST）; $ jsondata = json_encode（$ postarray）;

Sorry its for PHP

对不起它的PHP
