Thank you for taking the time to post that test page. I haven't tested
this in any older version of Opera but it seems to be that Opera is
quite behind on their Ajax support. I couldn't find much info on it but
this is definitely just an Opera limitation. I even hacked up the
quirksmode Ajax functions and monitored every last detail of the
XMLHttpRequest and Opera doesn't follow a lot of the specs.. for
example, on asynch calls it completely skips the Receiving (3)
readyState. I also tried Content-Type: text/xml and neither the
responseText nor responseXML are given any useful values for anything
but 200. There's nothing you can do about this other than write a patch
for Opera and I have no idea where to start there..
However, a completely viable option would be to use a custom header. I
tested this and Opera does set them and retrieve them correctly for all
response statuses. You could use Prototype's current JSON convention or
make up your own...
PHP:
header('X-JSON: ({"key":"Your value"})'); //Prototype already supports this
header('X-responseText: Some text here'); //make sure this is escape
properly if necessary
Javascript:
onFailure: function(transport, json){
alert(json.key); //"Your value"
var responseText = (transport.responseText ? transport.responseText
: transport.getResponseHeader('X-responseText'));
alert(responseText);
}
There is nothing Prototype can do about this and I don't warrant any
such hacks be implemented, I think you'll just have to live with it
until Opera gets their XMLHttpRequest support complete. I recommend the
JSON approach as PHP has a nice json_encode and Prototype already
supports it, all of your encoding will be handled for you.
