oper.yahoo.net/common/json.html#callbackparam' onclick="window.open('http://developer.yahoo.net/common/json.html#callbackparam');return false;">tutorial provided by Yahoo! for a good overview of how this transport mechanism works. Note, as indicated in the tutorial above, the server is responsible for writing out not just the data, but also a JavaScript function call that tells the client that the response has arrived. The client passes the name of the function to call as the "callback" URL parameter.
NOTE: if you use this DataSource to contact Yahoo web services, remember to include output=json in the dataURL, as well as a Yahoo developer ID.
