Map directions request on webOS

Very simple, but not well documented.

First, here’s a typical call to launch the maps app and display a position (latitude, longitude + title) on the map:

this.controller.serviceRequest("palm://com.palm.applicationManager", {
method:
"open",
parameters: {
id:
"com.palm.app.maps",
params: {
query: escape(latlong) +
"(" + encodeURIComponent(title) + ")"
}
}
});

To launch the maps app and bring up the directions panel instead, replace query with daddr:

this.controller.serviceRequest("palm://com.palm.applicationManager", {
method:
"open",
parameters: {
id:
"com.palm.app.maps",
params: {
daddr: escape(latlong) +
"(" + encodeURIComponent(title) + ")"
}
}
});
