jQuery.getJSON（）。错误（）没有在404错误上执行

Question

This is a brief outline of my code:

$.getJSON(json_url, function(data) {
    // application logic
}).error(function() {
    console.log("error");
});

The problem is that when the server returns a 404 error, it does not appear to be handled as there is no console.log() saying error, but there is a GET request failure with a code of 404 (Not Found) showing up in the console.

I am using jQuery 1.9.0.

Is there some simple error I am making?

Answer 1

Due to the nature of JSONP requests, the error callback is not called for those.

From the docs :

When data is retrieved from remote servers (which is only possible using the script or jsonp data types), the error callbacks and global events will never be fired.
