Hi,
I use Maps API Directions to get the distance and time for a route.
That works fine.
Now I want to show on the Site only the first step and the last step
of the route (with the adress)
This is the script I use :
var map;
var gdir;
var geocoder = null;
var addressMarker;
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
gdir = new GDirections(map, document.getElementById
("directions"), {getSteps:true});
//groute = new GRoute(map, document.getElementById("route"),
{getSteps:true});
GEvent.addListener(gdir, "load", onGDirectionsLoad);
//GEvent.addListener(groute, "load", onGRouteLoad);
GEvent.addListener(gdir, "error", handleErrors);
setDirections("fromAddress, toAddress, locale",
{getSteps:true});
}
}
function setDirections(fromAddress, toAddress, locale) {
gdir.load("from: " + fromAddress + " to: " + toAddress,
{ "locale": locale });
}
function handleErrors(){
if (gdir.getStatus().code == G_GEO_UNKNOWN_ADDRESS)
alert("No corresponding geographic location could be found for
one of the specified addresses. This may be due to the fact that the
address is relatively new, or it may be incorrect.\nError code: " +
gdir.getStatus().code);
else if (gdir.getStatus().code == G_GEO_SERVER_ERROR)
alert("A geocoding or directions request could not be
successfully processed, yet the exact reason for the failure is not
known.\n Error code: " + gdir.getStatus().code);
else if (gdir.getStatus().code == G_GEO_MISSING_QUERY)
alert("The HTTP q parameter was either missing or had no value.
For geocoder requests, this means that an empty address was specified
as input. For directions requests, this means that no query was
specified in the input.\n Error code: " + gdir.getStatus().code);
// else if (gdir.getStatus().code == G_UNAVAILABLE_ADDRESS)
<--- Doc bug... this is either not defined, or Doc is wrong
// alert("The geocode for the given address or the route for
the given directions query cannot be returned due to legal or
contractual reasons.\n Error code: " + gdir.getStatus().code);
else if (gdir.getStatus().code == G_GEO_BAD_KEY)
alert("The given key is either invalid or does not match the
domain for which it was given. \n Error code: " + gdir.getStatus
().code);
else if (gdir.getStatus().code == G_GEO_BAD_REQUEST)
alert("A directions request could not be successfully parsed.\n
Error code: " + gdir.getStatus().code);
else alert("An unknown error occurred.");
}
function onGDirectionsLoad(){
document.getElementById("getDistance").value = gdir.getDistance
().meters ;
document.getElementById("getDuration").value = gdir.getDuration
().seconds ;
//document.getElementById("getSteps").value = groute.getSteps
() ;
}.
I must say that JavaScript give me headache.
Can somebody describe me how can I do this?
Thank You.
