Firstly the javascript you have posted seems to be incorrect - the blocks
of code have mismatched {} , ie onException: is not part of the options
object literal passed to Ajax.Request - but that might have been copy and
pasting problems
- have you confirmed that the ajax response has the a Content-Type:
application/json header?
- if so have you tried to console.log the xhr.ResponseText - the JSON
might be invalid?
- "onsuccess" should be "onSuccess"
- you are doing a strictly equal test (===), you might consider just
checking equal (==) first get it working and then check strict equal
and to answer your main question - the onSuccess is a callback function -
returning a value is not really something to be done for a callback
function - you can set/get other global variables and you should be able to
access the variables in the method you have written
Let me know if anything doesn't make sense
