Javascript / jQuery example error

Dear FlightAware staff,

I am interested in using FlightXML API to show the real time flight location on a map.

I tried the example listed in the below page for REST / JSON using Javascript / jQuery.
Used the exact same code, just with my username and API key
flightaware.com/commercial/flig … t#examples

However I keep getting the following error for any flight I input
Failed to decode route: [object Object]

could you please advise what the problem is?
thank you so much for your help!


 This example uses:
 * the FlightXML2 FlightInfoEx and DecodeFlightRoute functions over REST:
 * Google Maps API:
 * jQuery, hosted by Google API

To help diagnose, you can try changing the error message to log the variable in a more displayable way.

alert('Failed to decode route: ’ + $(data).serialize());

However, keep in mind that not all flight routes can actually be decoded by DecodeFlightRoute, and may still legitimately result in an error.

Thank you very much for your prompt reply bovineone.

I planned to use FlightXML API to track the live location of the air plane for shipment tracking purpose.

Since DecodeFlightRoute function does not guarantee results, could you please suggest some other function I can use for this purpose?

InFlightInfo will return the current position (lat, lon, altitude, etc) of a flight. flightaware.com/commercial/fligh … FlightInfo
