I tried a lot to use networklink tag.. to update a content in google maps Api v3.. but google support told me that networkling update is not supported in google maps.. only in earth.
So I found geoXml3 api.. but there isn't documentation ..
recently I found in http://code.google.com/p/geoxml3/source/browse/branches/polys/geoxml3.js
that implements networklink, here a part of geoxml3.js code:
*// Apply the link
if ((networkLink.link.refreshMode === 'onInterval') &&
(networkLink.link.refreshInterval > 0)) {
// Reload at regular intervals
setInterval(parserName + '.parse("' + networkLink.link.href + '")',
1000 * networkLink.link.refreshInterval);
} else if (networkLink.link.refreshMode === 'onChange') {
if (networkLink.link.viewRefreshMode === 'never') {
// Load the link just once
doc.internals.parser.parse(networkLink.link.href, doc.internals.docSet);
} else if (networkLink.link.viewRefreshMode === 'onStop') {
// Reload when the map view changes
}*
Does anyone used or are using that?
Are there some example of networklink using geoxml3 api ?
My test cases for network links:
http://www.geocodezip.com/geoxml3_test/v3_geoxml3_local_network_link_test.html
http://www.geocodezip.com/geoxml3_test/v3_geoxml3_local_network_link_test_local.html
The major caveat of using geoxml3 is that without a proxy, everything needs to be on the same domain.
You might investigate geoxml-v3, it is a port to the Google Maps API v3 of the more mature GeoXml (from the Google Maps API v2).

After preparing the migration of my chrome manifest V2 extension to manifest V3 and reading about the problems with persistent service workers I prepared myself for a battle with the unknown. My V2 background script uses a whole bunch of globally declared variables and I expected I need to refactor that.
But to my great surprise my extension background script seems to work out of the box without any trouble in manifest V3. My extension uses externally_connectable. The typical use case for my extension is that the user can navigate to my website 'bla.com' and from there it can send jobs to the extension background script.
My manifest says:
"externally_connectable": {
"matches": [
"*://localhost/*",
"https://*.bla.com/*"
]
}
My background script listens to external messages and connects:
chrome.runtime.onMessageExternal.addListener( (message, sender, sendResponse) => {
log('received external message', message);
});
chrome.runtime.onConnectExternal.addListener(function(port) {
messageExternalPort = port;
if (messageExternalPort && typeof messageExternalPort.onDisconnect === 'function') {
messageExternalPort.onDisconnect(function () {
messageExternalPort = null;
})
}
});
From bla.com I send messages to the extension as follows
chrome.runtime.sendMessage(EXTENSION_ID, { type: "collect" });
From bla.com I receive messages from the extension as follows
const setUpExtensionListener = () => {
// Connect to chrome extension
this.port = chrome.runtime.connect(EXTENSION_ID, { name: 'query' });
// Add listener
this.port.onMessage.addListener(handleExtensionMessage);
}
I tested all scenarios including the anticipation of the famous service worker unload after 5 minutes or 30 seconds inactivity, but it all seems to work. Good for me, but something is itchy. I cannot find any documentation that explains precisely under which circumstances the service worker is unloaded. I do not understand why things seem to work out of the box in my situation and why so many others experience problems. Can anybody explain or refer to proper documentation. Thanks in advance.
i have this code:
if(navigator.platform.indexOf("iPhone") != -1 || navigator.platform.indexOf("iPod") != -1 || navigator.platform.indexOf("iPad") != -1) {
window.open("https://maps.google.com?saddr=Current+Location&daddr=" + lat + "," + lon);
}
else {
window.open("https://www.google.com/maps/dir/Current+Location/" + lat + "," + lon);
//window.open("https://maps.google.com?saddr=Current+Location&daddr=" + lat + "," + lon);
}
I know that lon and lat have correct values. it works on all desktop browsers and on an android phone i have tested (gives me the directions), but when i window.open runs on the iphone it loads google maps and it says "route not found"..
is this code not supposed to work on and ios device?
You have two methods to embed Google Maps URL in your iOS app.
Using OpenInGoogleMapsController class.
URL Scheme method.
In the first one it is easy to build links to open a map (or display Street View or directions) directly in Google Maps for iOS. Rather than creating URLs by hand, you can create map requests using Objective-C classes and types, so you can take advantage of all the type-checking and code hinting you've come to expect from Xcode.
For Direction follow this code:
GoogleDirectionsDefinition *defn = [[GoogleDirectionsDefinition alloc] init];
defn.startingPoint =
[GoogleDirectionsWaypoint waypointWithQuery:#"221B Baker Street, London"];
defn.destinationPoint = [GoogleDirectionsWaypoint
waypointWithLocation:CLLocationCoordinate2DMake(51.498511, -0.133091)];
defn.travelMode = kGoogleMapsTravelModeBiking;
[[OpenInGoogleMapsController sharedInstance] openDirections:defn];
To launch the Google Maps app for iOS and optionally perform one of the supported functions, use a URL scheme of the following form:
comgooglemaps://?parameters
Use the Display Direction scheme to request and display directions between two locations. You can also specify the transportation mode.
An example URL is below to display transit directions between Google NYC and JFK Airport:
comgooglemaps://?saddr=Google+Inc,+8th+Avenue,+New+York,+NY&daddr=John+F.+Kennedy+International+Airport,+Van+Wyck+Expressway,+Jamaica,+New+York&directionsmode=transit
Hope tat Helps!!
I am trying to find a specific listing via the google-maps-places API, but I don't get any results. This is strange to me, as there is a Google+ page and also a google-maps entry.
Let's take a look at the links:
Google+:
https://plus.google.com/115673722468988785755/about
Maps:
https://www.google.de/maps/place/AMWAY+Beratung+%26+Vertrieb+Haegebarth/#53.171976,9.465828,17z/data=!3m1!4b1!4m2!3m1!1s0x47b106116fc69d69:0xe17811ab2780c71d
If I use the very same coordinates from the maps entry in my nearby search and use the name from the entry as the keyword (or location for what it's worth) the results is empty.
Places-API (with exact same coordinates):
https://maps.googleapis.com/maps/api/place/nearbysearch/json?sensor=false&radius=2000&name=amway&location=53.171976,9.465828&language=de-DE&key=YOURKEY
I can of course imagine that the db for the Google+ POIs is a different one. But then again I don't see how the maps api does not find what I can find on the maps web app.
Thanks a lot for any help!
Try something like this:
map.places.nearbySearch({
location: latLng,
rankBy: google.maps.places.RankBy.DISTANCE,
types: ['shop'], // optional
name: "AMWAY Beratung & Vertrieb Haegebarth" // optional
},function(results, status){
if (status == google.maps.places.PlacesServiceStatus.OK) {
// The thing you need should be result[0]
// console.log(results[0]);
if (results[0].name == "AMWAY Beratung & Vertrieb Haegebarth") { // optionally check the type
// You have your place :)
}
}
}
What a workaround! Rumours are that the Google Maps JS API v3.20 or later will allow us to trigger click events on POIs, thereby getting Place objects directly.
i am trying to build a google earth view showing cities, but i stuck with the kml parser geoxml3. I have a javascript building a google map at first showing the locations i want. this works fine. I call the function from a php script providing it an address and kml file reference from database. The function builds the map, sets a flag 'map_finished' as a control flag when all ran fine and calls the build google earth view function.
// Get maps and earth from google
google.load( 'maps', '2.s', {'other_params': 'sensor=true'} );
google.load( 'earth', '1' );
//Google Earth Initializer
function initObjectEarth() {
// Check if Google Earth plugin is installed
if( gm_loaded ) {
this.ge_plugin_installed = google.earth.isInstalled();
if( this.ge_plugin_installed ) {
google.earth.createInstance( 'inmap', geSuccessCallback, geFailureCallback );
ge_loaded = true;
} else {
alert( 'Your Browser has not yet installed the Google Earth plugin.
We recommend installing it to use all features!' );
return false;
}
}
}
// Success handler
function geSuccessCallback( object ) {
this.ge = object;
this.ge.getWindow().setVisibility( true );
this.kmlParser = new geoXML3.parser();
}
// Error handler
function geFailureCallback( object ) {
alert( 'Error: ' + object );
}
The geoxml parser uses the ProjectedOverlay class. Both libraries are loaded into document head. When the parser is getting instatiated it requests a ProjectedOverlay instance. This class throws a
Error: **google.maps is undefined**
error in firebug for the following statement
ProjectedOverlay.prototype = new google.maps.OverlayView();
In my script file i have declared vars including
var gm //for google map
var ge //for google earth
gm is set in the function that builds the google map.
I wonder how to fix this issue. I tried the getProjection() thing i found in web as well as
ProjectedOverlay.prototype = new google.maps.OverlayView().prototype;
with no success. This topic is absolutely new to me and i cannot figure out how to fix it neither from the documentation of OverlayView nor from google search.
What did i forget or do wrong?
The call to the geoXML3 constructor is wrong, you must pass the google.maps object as a parameter (...hence the "google.maps is undefined" error).
this.kmlParser = new geoXML3.parser({map: gm}); // gm for google map
I have created a custom Google Maps projection using the Google Maps Javascript API V2. It looks like this, as per the API specification:
function PProjection(levels) {
this.fromLatLngToPixel = function(latlng, zoom) {
...
};
this.fromPixelToLatLng = function(pixel, zoom) {
...
};
this.tileCheckRange = function(tile, zoom, tilesize) {
...
};
this.getWrapWidth = function(zoom) {
...
};
}
Previously, I had my version of the API set to 2.147 and everything worked fine. However, Google recently made the lowest version available 2.193. This new version breaks my projection. Whenever I try to add a marker, I get the following error in Firebug:
d.getNearestImage is not a function
According to this post a new method called
GProjection.getNearestImage(pixel,zoom,centrepixel)
was added in version 2.148, so it kind of makes sense that this problem would occur if I used a version of the API above 2.147. However, there is no note in the reference manual of an official change in the API. I added a dummy method of this name to my projection, but no luck. Any ideas on how to fix my projection or on how to revert to 2.147?
You can request a specific version through this method: http://groups-beta.google.com/group/google-maps-api/web/javascript-maps-api-versioning
