AJAX::OnSuccess network failure and status 0
Reported by Radek Pech | April 25th, 2008 @ 08:45 AM | in 1.6.1
The description of OnSuccess (Ajax.Request) says that this event is rised only for the server response 2YZ (i.e. 200, 201, etc.).
But when the request times out (e.g. server is down), it returns readyState == 4 and status == 0 and the OnSuccess is called.
To solve the timeouts, you have to use this code:
new Ajax.Request('/some_url',
{
onFailure: function(transport) {
alert('Error: '+transport.status);
}
onSuccess: function(transport) {
if (transport.status == 0) {
alert('Timeout error');
} else {
alert('Response: '+transport.responseText);
}
}
);
This collides with the advantage gain from using OnSuccess/OnFailure instead of onComplete with status testing.
Tested on FF 2.0.0.14
