Resource interpreted as other but transferred with MIME type text/javascript?

Question

I keep getting "Resource interpreted as other but transferred with MIME type text/javascript.", but everything seems to be working fine. This only seems to be happening in Safari 4 on my Mac.

I was advised to add "meta http-equiv="content-script-type" content="text/javascript" to the header, although that did nothing.

Answer 1

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.

Answer 2

i received this error due tu a missing element which a jquery plugin tried to call via js var btnChange i commented the none needed (and non existent) images out and the warning (google chrome dev tools) was fixed:

$(mopSliderName+" .sliderCaseRight").css({backgroundImage:"url("+btnChange.src+")"});

The (webkit-based) browser is issuing a warning that it has decided to ignore the mimetype provided by the webserver - in this case text/javascript - and is applying a different mimetype - in this case "other".

It's a warning which users can typically ignore, but a developer might find useful when looking for clues to a problem. For this example it might explain why some javascript wasn't being executed.

Answer 4

Your web server is sending the content with a certain MIME type. For example, a PNG image would be sent with the HTTP header Content-type: image/png. Configure your web server or script to send the proper content type.

Answer 5

It does cause issues if your are calling a javascript that adds functionality, it is likely to fail, as it does for me. No real answers yet.

Answer 6

I was getting this error due to a script with bad permissions bringing up a HTTP 403 error. I gave it read and execute rights across the board and it worked.

Answer 7

There is a setting for the Apache MIME module where it misses adding the type for javascript, to resolve it, simply open the .htaccess file OR httpd.conf file, add the following lines

<IfModule mod_mime.c>
  AddType text/javascript .js
</IfModule>

Restart the apache server, issue will be resolved.
