Hi all,
I have this code:
new Ajax.Request(''non_existant.file'', {
onSuccess:function(){alert("yay");},
onFailure:function(){alert("boo");}
});
Why does the onFailure alert never get called? It works fine if I use
a real file (onSuccess gets called).
Thanks,
Douglas
I believe onFailure is only a callback method for errors that happen on
the server (you would have to have caught some kind of error condition
in the server side code and explicitly initiated the onFailure method in
your response), not on the client during the attempted transport/request
to the server...
I think what you want is:
try
{
new Ajax.Request(''non_existant.file'', {
onSuccess:function(){alert("yay");},
onFailure:function(){alert("boo");}
});
}
catch (e)
{
doSomething();
}

Not sure then... I use my own AJAX classes. Hopefully someone else will chime in to help you. -----Original Message----- From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org [mailto:rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Douglas Livingstone Sent: Tuesday, February 14, 2006 10:59 AM To: rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org Subject: Re: [Rails-spinoffs] onFailure fails? 2006/2/14, Ryan Gahl <Ryan.Gahl-nlycWCgr5/vuufBYgWm87A@public.gmane.org>:> I believe onFailure is only a callback method for errors that happenon> the server (you would have to have caught some kind of error condition > in the server side codeI''m looking to catch a 404 error here.

There''s a on404 event you could catch:
new Ajax.Request(''non_existant.file'', {
onSuccess: function(){alert("yay");},
on404: function(){alert("404")}
})

Does anyone know what the serer should respond with to initiate onFailure?

i think the function is triggered at a responsecode < 200 or > 300 eg. 404 brgds On 2/14/06, Robin Haswell <rob-gyMb1R/nBgNh8AIihN9Rc9BPR1lH4CV8@public.gmane.org> wrote:> > Does anyone know what the serer should respond with to initiate onFailure? > > Douglas Livingstone wrote: > > 2006/2/14, Martin Ström <mlists-99Sk8hLoGLv2eFz/2MeuCQ@public.gmane.org>: > >> There''s a on404 event you could catch: > >> > >> new Ajax.Request(''non_existant.file'', { > >> onSuccess: function(){alert("yay");}, > >> on404: function(){alert("404")} > >> }) > >> > >> > > > > Aah, thanks, that''s the trick. onFailure only gets called with a > > remote request.
