#13917 closed bug (notabug)

jQuery does not parse json when the response to ajax requests is unsuccessful

It does the dataType conversion only if ( status >= 200 && status < 300
status === 304 ) is true otherwise the response is passed as such to the corresponding handler. That is if the request is a failure then the response is not parsed as per the expected dataType.

The parsed data is only passed to the .done() handler anyway. If you want to do it yourself, use dataType: text and call $.parseJSON() on the .responseText regardless of the HTTP code.

As of this commit: https://github.com/jquery/jquery/commit/eebc77849cebd9a69025996939f930cbf9b1bae1 parsed JSON is available in case of failures as the responseJSON field of the jqXHR instance.

$.ajax( /* ... */ ).fail( function( jqXHR ) {
    console.log( jqXHR.responseJSON )
} );

So there's no need to do it the hard way ;)
