You're quite right -- makeRequest is a vital function for most OpenSocial applications, and a number of usage examples are available. In addition to Raman's link, check out the following pages for snippets demonstrating makeRequest:
http://code.google.com/p/opensocial-resources/wiki/GadgetsMakeRequest http://code.google.com/apis/opensocial/articles/makerequest.html On your back-end, all you need is a script that accesses data from your database and returns the data as XML, JSON, or plain text. Then you point makeRequest at this script, specify the content type, and it will retrieve the data and invoke its callback when the data is available. Let me know if you have any more questions on this. - Jason On Sep 11, 11:09 pm, Ramanpreet Singh <[EMAIL PROTECTED]> wrote: > Hi Kogan > > I am sure this will get you > started.http://code.google.com/apis/opensocial/docs/0.7/devguide.html#Remote_... > > Raman > > Kogan wrote: > > Hi again, > > > I have a question regarding "makeRequest" now - > > I read the article about it, but I didn't quite understand it all the > > way: > > > because it seems to me that this is the most important and most used > > method I'll ever use (because most of the > > time I'll address my DataBase, for example) - and I didn't find a > > SIMPLE example on how to retrieve something from my DataBase do it. > > I guess I need to understand better how are these asynchronous calls > > handled on my back end server ?(is there a reading material about > > that?) and then maybe the picture will be clearer... > > > As you can see, I need some clarifications > > (maybe some of the questions above are quite trivial, sorry about that > > too) > > > :) > > > Thanks, > > Kogan. > > > On Jul 29, 2:07 am, Jason <[EMAIL PROTECTED]> wrote: > > >> My reply in the thread below might help explain things a bit: > > >>http://groups.google.com/group/opensocial-orkut/browse_thread/thread/... > > >> In general, yes, you can build an OpenSocial application entirely with > >> JavaScript inside a gadget (XML) wrapper.
