Javascript Question

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

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:

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


here's the request:

$.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);
}
});


Does anyone have a workaround for this?

thanks

Paul

Answer

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 application/javascript.

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