Wrong arguments to window.onerror when using dataTables 1.10.19 (and 1.10.20)

davispuh

See example here: https://jsfiddle.net/z81kdfjv/1/

But basically

$('#test').DataTable({
          processing: true,
          serverSide: true,
          ajax: "?test",
        });

window.onerror = function(message, source, lineno, colno, error) {
    console.log("message: " + message);
    console.log("source: " + source);
    console.log("lineno: " + lineno);
}

In console there will be

message: [object Object]
source: [object Object]
lineno: 7

_fnLog( oSettings, 0, 'Ajax error', 7 ) will call _fnCallbackFire( settings, null, 'error', [ settings, tn, msg ] );
Which will cause $(settings.nTable).trigger( e, args ); to be called with these args.

Thank you for this. I'll look into that for the next patch release of DataTables.

I've just been looking into and I've not actually managed to recreate the error with the linked test case - the window.onerror doesn't get triggered at all - which is what I would expect here, the alert is shown instead. Is there something else that needs to be done?
