Javascript – “Resource interpreted as script but transferred with MIME type text/html.”

http-headersjavascriptjquerymacossafari

Sorry if this is actual duplicate but I haven't managed to find answer for my problem.

I load the script with jQuery's $.getScript. But it causes the following error:

Resource interpreted as script but transferred with MIME type text/html.

The problem appears only in Safari under Mac OS

If to look on headers received from the server, they contain Content-Type:application/x-javascript, so I really don't understand what the problem is.

Resource interpreted as script but transferred with MIME type text/html.

Technically that's not an error but a notice / warning and should not cause any issues in particular; if anything it's a good indication that some browsers may choose to ignore such a response.

The correct Content-Type response header for JavaScript according to the RFC is:

Content-Type: application/javascript

Previous values of text/javascript and application/x-javascript are either obsolete or deprecated respectively; that said, IE <= 8 will only accept the former so be careful when making any changes to your documents.

The most common way to get the error is with the following code:

<img src="" class="blah" />

A blank url is a shortcut for the current page url, so a duplicate request is made which returns content type html. The browser is expecting an image, but instead gets html.

Html – Resource interpreted as other but transferred with MIME type text/html

Thanks to Pekka for asking me to show the code -- I noticed several problems, made changes, and one of them (I suspect I know which) has fixed the problem:

$.ajax({
    url: url, 
    dataType: 'html',            //  <-- changed the dataType to "html"
    async: true,
    success: function(data) {
        callback(data);
    },
    error: function(request, status, error) {
        callback(undefined);
    }
});
