By adding a callback argument, you are telling jQuery that you want to make a request for JSONP using a script element instead of a request for JSON using XMLHttpRequest.

JSONP is not JSON. It is a JavaScript program.

Change your server so it outputs the right MIME type for JSONP which is <code>application/javascript</code>.

(While you are at it, stop telling jQuery that you are expecting JSON as that is contradictory: <code>dataType: 'jsonp'</code>).

In my case, I use

<pre><code>$.getJSON(url, function(json) { ... });
</code></pre>

to make the request (to Flickr's API), and I got the same MIME error.
Like the answer above suggested, adding the following code:

<pre><code>$.ajaxSetup({ dataType: "jsonp" });
</code></pre>

Fixed the issue and I no longer see the MIME type error in Chrome's console.

blocks|key|153702|text|如果您的代理服务器或容器在提供.js文件时添加了以下标头，则会强制某些浏览器对MIME类型执行严格检查：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|153703|X-Content-Type-Options:+nosniff|code-block|syntax|javascript|153704|删除此头以阻止Chrome执行MIME检查。|153705|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

If your proxy server or container adds the following header when serving the .js file, it will force some browsers such as Chrome to perform strict checking of MIME types:

<pre><code>X-Content-Type-Options: nosniff
</code></pre>

Remove this header to prevent Chrome performing the MIME check.

blocks|key|155085|text|仅供参考，我在Chrome控制台上也遇到了同样的错误。我认为是我的AJAX函数引起的，但我取消了从/javascripts/ajax-vanilla.min.js到/javascripts/ajax-vanilla.js的精简脚本的注释。但实际上，源文件位于/javascripts/src/ajax-vanilla.js。所以在Chrome中，即使找不到文件，你也会得到糟糕的MIME类型错误。在这种情况下，错误消息被描述为text/plain+bad+MIME类型。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|155086|entityMap^0|1D|W|2A|S|3L|W|5X|A|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

FYI, I've got the same error from Chrome console. I thought my AJAX function causing it, but I uncommented my minified script from <code>/javascripts/ajax-vanilla.min.js</code> to <code>/javascripts/ajax-vanilla.js</code>. But in reality the source file was at <code>/javascripts/src/ajax-vanilla.js</code>. So in Chrome you getting bad MIME type error even if the file cannot be found. In this case, the error message is described as <code>text/plain</code> bad MIME type.

blocks|key|151176|text|我在使用带有自定义404错误页的IIS+7.0时遇到了此错误，尽管我怀疑任何404页都会发生这种情况。服务器返回了无法(正确)执行的具有text/html+mime类型的html+404响应。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|151177|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I encountered this error using IIS 7.0 with a custom 404 error page, although I suspect this will happen with any 404 page. The server returned an html 404 response with a text/html mime type which could not (rightly) be executed.

blocks|key|153720|text|对于记录和谷歌搜索用户，如果您是.NET核心开发人员，则应该手动设置内容类型，因为它们的默认值为null或空：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|153721|var+provider+=+new+FileExtensionContentTypeProvider();

For the record and Google search users,
If you are a .NET Core developer, you should set the content-types manually, because their default value is null or empty:

<pre><code>var provider = new FileExtensionContentTypeProvider();
app.UseStaticFiles(new StaticFileOptions
{
 ContentTypeProvider = provider

I faced this problem when trying to run an existing application on a new IIS 10.0 installation

I'm trying to access a script as JSON via AJAX, which works fine on Safari and other browsers but unfortunately will not execute in Chrome. It's coming with the following error:

<blockquote>
 Refused to execute script from '*' because its MIME type ('application/json') is not executable, and strict MIME type checking is enabled.
</blockquote>

Here's the request:

<pre><code>$.ajax({
 url: "http://some_url/test.json?callback=?",
 type: "GET",
 dataType: 'json',
 cache: true,
 success: function (data, status, error) {
 console.log('success', data);
 },
 error: function (data, status, error) {
 console.log('error', data, status, error);
 }
});
</code></pre>

Does anyone have a workaround for this?

Chrome refuses to execute an AJAX script due to wrong MIME type

我正在尝试通过AJAX访问JSON脚本，它在Safari和其他浏览器上运行良好，但不幸的是不能在Chrome中执行。它会出现以下错误：拒绝执行来自'*‘的脚本，因为其MIME类型('application/json')不可执行，并且启用了严格的MIME类型检查。下面是请求：$.ajax({    url: "http:...
