Heh, well...
If we define a successful response as one defined by HTTP/1.1
standards, then any 2xx/3xx based response should be considered
successful. However, I can see that if you are interacting with a
layer such as $.ajax() that specified an expected dataType as a return
that it should reasonably error to some degree.
It is definitely a tangential issue - And is most likely apparent to
any RESTful applications that would rely on status codes to manipulate
client-side interaction.
Perhaps, a solution would be to have the option of defining callbacks
per status code.
E.g. $.ajax(..., {
'onStatusCode':
{ '200': {
'dataType': 'json',
'success': function(data) { },
'error': function(data) { }
}
'204': {
'success': function () {
}
}
}
}
- Or something that degree that would allow a 'lower-level' of
interaction with how $.ajax() would handle responses.
