> what does asynchronous imply here? Description http://econym.org.uk/gmap/async.htm Implication, you can't use results until after they have returned
Cross-posted in v3 group > You can access the code at > http://web.iiit.ac.in/~vishal.gargug08/test/index.php You have dirn1.loadFromWaypoints([p11.toUrlValue(6),p11.toUrlValue(6)], {getPolyline:true}); dirn2.loadFromWaypoints([p22.toUrlValue(6),p22.toUrlValue(6)], {getPolyline:true}); These only fire off requests to Google's servers, without waiting for a response. So dirn1 fires, followed by dirn2, and then whatever code comes next - but results are not yet available. Note that there are speed limits on the rate at which you can fire requests, to prevent abuse. Firing multiple requests is likely to fail. Search this group for handling multiple requests, or http://econym.org.uk/gmap/geomulti.htm var p1 = dirn1.getPolyline().getVertex(0); There is no polyline yet. If you want to do something with the results from the requests, you need to listen for when they available by setting up a 'load' event listener and using the results only in the callback. http://econym.org.uk/gmap/steps.htm -- You received this message because you are subscribed to the Google Groups "Google Maps API V2" group.
