[Proto-Scripty] Re: checked !status in line 1496? (prototype-1.6.1.RC3)
Yes! The core devs do need to address whether or not this
Ajax.Request#getStatus() behavior will be fixed.
All non-HTTP requests (namely file:) return a status of 0. A function like
the following needs to be added, probably in Ajax.Request#getStatus()
isHttp: function() {
var pcol = String(this.url).match(/^([a-z]+)?\:/i);
if (!pcol) {
return window.location.protocol.match(/^https?\:/);
}
if (pcol[1] == 'http') {
return true;
}
},
In my opinion, the status should be zero only on failure and an
onNetworkError or the like should be fired in place of on0 (Firing on0
seems kludgey). Other error status codes (such as 12002, 12007, 12029,
12030, 12031, 12152 and 13030) need to be mapped to a status of 0 and fire
onNetworkError (see "Ajax: the Complete Reference" by Thomas Powell -
http://books.google.com/books?id=p9hrjVMAeYkC&pg=PA180 )
Then, as you mentioned, Ajax.Request#success() would then be return
(status> = 200 && status <300);
With the current state of Prototype, you'll need to manually interpret a
success as a failure when the request is HTTP.

> Looks like success() returns TRUE all the time as foolged said. Yes, if getStatus returns 0 (either because the HTTP status code really came back from the browser as 0, or because the browser didn't supply one at all), then success will return true. This has been noted before.[1][2] I'd love to hear from one of the core devs (NOT just someone active on this list like myself) *why* zero is considered success, because it doesn't make sense to me. The server being offline is certainly not a successful outcome. Most of the contributors to Prototype are not dumb, it's there for a reason, I just want to know what the reason is since they didn't feel it deserved a comment in the source.
