IE prompts to open or save json result from server
提问by iLemming
Internet explorer in compatibility mode gets the data from the server in an ajax callback method, and pops-up a dialog if I want to save the data or open. How to get rid of that?
兼容模式下的浏览器通过ajax回调的方式从服务器获取数据，如果我想保存数据或打开，会弹出一个对话框。如何摆脱它？
client says:
客户说：
$.ajax({
type:'POST',
data: $("#UIdlgHolder > form").serialize(),
url: $("#UIdlgHolder > form").attr("action"),
success: function (data, textStatus, jqXHR) {
{
alert(data.message);
}
}
server answers:
服务器回答：
return new JsonResult { Data = new { result = false, message = "Yay!" } };

Sounds like this SO question may be relevant to you:
听起来这个SO问题可能与您有关：
How can I convince IE to simply display Application json rather than offer to download
我怎样才能说服 IE 简单地显示应用程序 json 而不是提供下载
If not:
如果不：
Have you tried setting the dataType expected in the ajax options? i.e. dataType: 'json'
您是否尝试过在 ajax 选项中设置预期的数据类型？即数据类型：'json'
Have you tried other content types such as 'application/json' or 'text/javascript'
您是否尝试过其他内容类型，例如“application/json”或“text/javascript”

Even though it's not supposedly the correct way, setting the content type to text/html made IE deal with this correctly for me:
尽管这不是正确的方法，但将内容类型设置为 text/html 使 IE 为我正确处理：
return Json(result, "text/html");
Works in all the version that F12 tools gives you in IE9.
适用于 F12 工具在 IE9 中为您提供的所有版本。

If using MVC, one way of handling this is to implement a base controller in which you override(hide) the Json(object) method as follows:
如果使用 MVC，处理此问题的一种方法是实现一个基本控制器，您可以在其中覆盖（隐藏）Json(object) 方法，如下所示：
public class ExtendedController : Controller
{
protected new JsonResult Json(object data)
{
if (!Request.AcceptTypes.Contains("application/json"))
return base.Json(data, "text/plain");
else
return base.Json(data);
}
}
Now, your controllers can all inherit ExtendedController and simply call return Json(model);...
现在，您的控制器都可以继承 ExtendedController 并简单地调用return Json(model);...
- without modifying the response content type for those browsers which play nicely (not <=IE9 !)
- without having to remember to use
Json(data, "text/plain")in your various Ajax action methods
- 无需修改那些运行良好的浏览器的响应内容类型（不是 <=IE9 ！）
- 无需记住
Json(data, "text/plain")在您的各种 Ajax 操作方法中使用
This works with json requests which would otherwise display the "Open or Save" message in IE8 & IE9 such as those made by jQuery File Upload
这适用于 json 请求，否则会在 IE8 和 IE9 中显示“打开或保存”消息，例如jQuery 文件上传

Sadly, this is just another annoying quirk of using Internet Explorer.
遗憾的是，这只是使用 Internet Explorer 的另一个恼人的怪癖。
The simple solution is to run a small .reg file on your PC, to tell IE to automaticallyopen .json files, rather than nag about whether to open/save it.
简单的解决方案是在您的 PC 上运行一个小的 .reg 文件，告诉 IE自动打开 .json 文件，而不是唠叨是否打开/保存它。
I've put a copy of the file you'll need here:
我已经把你需要的文件的副本放在这里：
You'll need to have Admin rights to run this.
您需要具有管理员权限才能运行它。

I changed the content-type to "text/html" instead of "application/json" server side before returning the response. Described it in a blog post, where other solutions have also been added:
在返回响应之前，我将内容类型更改为“text/html”而不是“application/json”服务器端。在博客文章中对其进行了描述，其中还添加了其他解决方案：

Have you tried to send your ajax request using POST method ? You could also try to set content type to 'text/x-json' while returning result from the server.
您是否尝试过使用 POST 方法发送 ajax 请求？您还可以尝试在从服务器返回结果时将内容类型设置为“text/x-json”。

Is above javascript code the one you're using in your web application ? If so - i would like to point few errors in it: firstly - it has an additional '{' sign in definition of 'success' callback function secondly - it has no ')' sign after definition of ajax callback. Valid code should look like:
上面的 javascript 代码是您在 Web 应用程序中使用的代码吗？如果是这样-我想指出其中的一些错误：首先-它在“成功”回调函数的定义中具有附加的“{”符号，其次-在定义ajax回调之后没有“）”符号。有效代码应如下所示：
$.ajax({
type:'POST',
data: 'args',
url: '@Url.Action("PostBack")',
success: function (data, textStatus, jqXHR) {
alert(data.message);
}
});
try using above code - it gave me 'Yay' alert on all 3 IE versions ( 7,8,9 ).
尝试使用上面的代码 - 它在所有 3 个 IE 版本（ 7,8,9 ）上给了我'Yay'警报。

I faced this while using jQuery FileUpload plugin.
我在使用jQuery FileUpload 插件时遇到了这个问题。
Then I took a look in their documentation, most exactly in the Content-Type Negotiation sectionand followed their suggestion for Ruby/Rails.
然后我查看了他们的文档，最准确的是在Content-Type Negotiation 部分，并遵循了他们对Ruby/Rails的建议。
render(json: <some-data>, content_type: request.format)
Which fixed the issue for me.
这为我解决了这个问题。
Quick Explanation: for old IE/Opera versions, this plugin will use an iframe with text/plainor text/htmlcontent-type, so if you force the response to json, browser will try download it. Using the same content-type as in the request will make it work for any browser.
快速说明：对于旧的 IE/Opera 版本，此插件将使用带有text/plain或text/html内容类型的 iframe ，因此如果您强制响应为json，浏览器将尝试下载它。使用与请求中相同的内容类型将使其适用于任何浏览器。

In my case, IE11 seems to behave that way when there is some JS syntax error in the console (doesn't matter where exactly) and dataType: 'json'has no effect at all.
就我而言，IE11 似乎在控制台中出现一些 JS 语法错误时（与确切位置dataType: 'json'无关）时表现得那样，并且根本没有任何影响。
