[Rails-spinoffs] Re: Opera and responseText Not working

[Colin Mollenhour]

It's too bad little things like this hold it back from being more usable, because I think Opera really is a great browser, better than IE and Safari in many ways and ahead of Firefox in some ways back in it's 1.x days.  It's future lies mostly in handheld devices since it is so lightweight and renders so quickly and they seem to be focusing on that anyway. I've run into very few cases that I have to do anything special to get Opera to work, so if it is deployed widely on handheld and other non-PC/Mac devices there is a good reason to support it. It even has the small screen view (Shift+F11) available in the standard desktop version which would make development for handhelds even easier. Is Opera's bug reporting system web-based? I'd like to watch the progress of it if you can give me a link or discussion board or something.  I don't really know much more than you about it, I just took your page and used quirksmode's ajax example as a skeleton to make a *very* barebones request function that alerted each bit of progress during the request, not even loading the Prototype library at all to quell any doubts as to Prototype's responsibility. Thanks, Colin [EMAIL PROTECTED] wrote: Wow glad to see that I'm not crazy =) I don't really know if I want to create such a lengthy workaround in my application for Opera. I like the browsers but lets face it, almost no one uses it and if is not supporting Ajax properly then there isn't much i am willing to do. I submitted a bug report to Opera but i think a lot of people are under the impressions that its a implementation issue due to some kind of browser checking in the code. I will leave that page on our servers in case you would like to submit another more detailed bug report as you seem to know a bit more about this than i do. Thanks again for you help. -Alex On Feb 14, 2:09 pm, Colin Mollenhour <[EMAIL PROTECTED]> wrote: 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.
