Question

Does this look like it should work? I’m wanting to generate directions from one latitude/longitude to another latitude/longitude.

var dirMap = new GMap2($("#dirMap").get(0));
var wp = new Array(2);
wp[0] = new GLatLng(35.742149,139.337218);
wp[1] = new GLatLng(35.735347,139.328485);

var marker = new GMarker(wp[1]);
dirMap.addOverlay(marker);
dirMap.setCenter(wp[0], 12);
dirMap.setUIToDefault();

// load directions
directions = new GDirections(dirMap);
directions.load("from: Waypoint1@21.742149,100.337218 to: Waypoint2@15.740815,100.3267");

The map loads fine, but the directions don’t come in. I’ve tried it this way too:

var dirMap = new GMap2($("#dirMap").get(0));
var wp = new Array(2);
wp[0] = new GLatLng(32.742149,119.337218);
wp[1] = new GLatLng(32.735347,119.328485);

var marker = new GMarker(wp[1]);
dirMap.addOverlay(marker);
dirMap.setCenter(wp[0], 12);
dirMap.setUIToDefault();

// load directions
directions = new GDirections(dirMap);
directions.loadFromWaypoints(wp);

Same thing… map but no directions. Any help is greatly appreciated, thank you in advance!

I can’t see anything obvious at first glance at your code, so my first guess is a failure coming back in for the GDirections request (I am also assuming you have checked the javascript error log for any errors, Tools/Error Console if you haven’t already done this).

I suggest you add an error handler for your GDirections object, this will give you some indication what is happening with your request:

GEvent.addListener(directions, "error", handleErrors);

and in the handleErrors callback have a look in:

directions.getStatus().code

Compare with the Geo Status Codes.

EDIT: Ok, I just tried out your code here and it works perfectly. I can only assume that there is some other problem on your page that is causing the issue. Can you post a link in the question so we can check it out ?
