I have a Google Maps elevation service (for my Geography of Pennsylvania students) that works fine with point clicks on Google's basemaps. I would like to add a kml layer showing PA counties. When I add it, the elevation infowindow no longer displays. Is there a way to add the kml but suppress its click response so that the elevation response shows?
Current code (partial):
function initialize() {
var mapOptions = {
zoom: 7,
center: centerOfPA,
mapTypeId: 'roadmap'
}
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var paCounties = new google.maps.KmlLayer('http://mapmaker.millersville.edu/arcgis/services/PAcounties/MapServer/KmlServer', {suppressInfoWindows: true});
paCounties.setMap(map);
// Create an ElevationService
elevator = new google.maps.ElevationService();
// Add a listener for the click event and call getElevation on that location
google.maps.event.addListener(map, 'click', getElevation);
}
Either suppress click events on the KmlLayer (clickable: false) or handle the click events and call the elevation service (with the latLng from that click event).
Here is a working example

I've included a google map on my webpage with a marker at the location. What I want to add is an existing infoWindow of that location when the page loads.
This is the code i have:
<script>
function initialize() {
var mapCanvas = document.getElementById('map-canvas');
var mapOptions = {
center: new google.maps.LatLng(51.257195, 3.716563),
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(mapCanvas, mapOptions);
new google.maps.Marker({
position: new google.maps.LatLng(51.257195, 3.716563),
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

Now the "AXA..." is an existing point of interest on google maps, how would i go about that my marker is actually 'linked' to that existing point of interest with the infowindow opened by default.
in short: i would like a marker on that location with the infowindow opened when the webpage loads.
I think the solution would be to first find the place_id and then add your marker using the place ID you found rather than using longitude and latitude.
I created a live demo here:
https://jsfiddle.net/qzo41qzd/
There is also an example in the documentation about placing a marker on the google map using place_id:
https://developers.google.com/maps/documentation/javascript/places#placeid
I am trying to add a map to my website, but I would like to have it show the business view by default rather than going from satellite to street view and then to business view.
Is this possible?
If business view is what is now called indoor map, once you reach the view you should like to show on a map, you could simply retrieve the link to the view or to the iframe embed code, as explained in https://support.google.com/maps/answer/144361?hl=en
indoor map example: https://goo.gl/maps/SAhHg5hhLrGdLjaJ9
However, embedding the map via iframe source code gives you limited chances of customization.
If you need a higher level of customization you can use the street view service of Maps Javascript API (you will need an API KEY )
example: http://jsfiddle.net/eg561mx8/
var lat2 = 48.87708978509529, lng2 = 2.3392088036591754;
var map;
var panorama;
var panoramaService;
var streetView;
function initialize() {
map = new google.maps.Map(
document.getElementById("map_canvas"), {
zoom: 14,
center: new google.maps.LatLng(lat2, lng2),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
streetView = map.getStreetView();
panoramaService = new google.maps.StreetViewService();
panoramaService.getPanoramaByLocation(
new google.maps.LatLng(lat2, lng2),
100,
function(streetViewPanoramaData, streetViewStatus) {
if (streetViewStatus != "OK") {
alert("no street view at this location I'm afraid");
} else {
streetView.setPosition(
streetViewPanoramaData.location.latLng);
streetView.setVisible(true);
}
}
);
}
i was checking out the google map api to integrate in my website.
made this page with what ever i could understand so far.
everything is working fine but there is just one thing, that i want three markers on the same map.
when i am adding more than one markers then the map stops working.
test link : http://goo.gl/X9q92s
you will have a better understanding if u see my link.
this is the code that i got from google map api.
and i edited it to get grey scale map with my desired marker box.
i just want to add two more....
Please help.
<script>
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
You should place your "new marker" code into its own function, like so:
function LoadMarkers(name, lat, lng) {
var MarkerLatLng = new google.maps.LatLng(lat, lng);
var MarkerOption = { map: map, position: MarkerLatLng, title: name};
var Marker = new google.maps.Marker(MarkerOption);
}
Putting this into its own function allows you to "refresh" the markers with ease, by simply invoking the function with a timer or some other event. A program I'm working on refreshes the map every few seconds, as my data source is constantly changing with new/removed/updated records that should be reflected immediately on the map. I think this is a great way to do this.
Then, in your program, you can create a loop that shoots the information for each marker in by invoking the LoadMarkers function. I've recently fallen in love with SqlDataReader.
Your loop would iterate through a SqlDataReader and each record read will invoke the script like so:
InvokeScript("LoadMarkers", New Object() {name, lat, lng})
This is a great moment to also add an InfoWindow for each marker.
var infowindow = new google.maps.InfoWindow(
{
content: "Content here"
});
As well as a click listener for the InfoWindows. ;)
google.maps.event.addListener(Marker, 'click', function () {
typeof infoWindowsOpenCurrently !== 'undefined' && infoWindowsOpenCurrently.close(); //If there is an InfoWindow currently open, close it
infowindow.open(map, Marker); //Open a new one for the selected marker
infoWindowsOpenCurrently = infowindow; //Set the new info window to the temporary variable
});
Some might not like this method of using a loop. I like it because I can "personalize" each marker for each record, while personalizing each of their InfoWindows too. In my code above, assume that "name" is a unique ID that lets you specify a specific marker for later use, such as identifying which marker was clicked and which InfoWindow is currently open.
First time ever posting on StackOverflow so tell me and be crude if I am doing something terribly wrong anyway. I recently created a KML file with maps.google.com and I uploaded the kml to my site, and I am trying to implement to the google maps that we created, but I am stumped as I have no errors but it does not show at all.
// North Campus SHuttle KML implementation
var redShuttle = new google.maps.KmlLayer (
'http://blazelist.org/maps/test/RedShuttle.kml'
);
redShuttle.setMap(map);
Can you share more code?
In my example your code is working:
function initialize()
{
var map = new google.maps.Map(document.getElementById("map"),
{
center: new google.maps.LatLng(22.7964,73.8456),
mapTypeId: google.maps.MapTypeId.TERRAIN
});
/* var kmlLayer = new google.maps.KmlLayer('http://blazelist.org/maps/test/RedShuttle.kml',
{
suppressInfoWindows: true,
map: map
});
*/
var redShuttle = new google.maps.KmlLayer ( 'http://blazelist.org/maps/test/RedShuttle.kml' ); redShuttle.setMap(map);
}

I am trying to create a site that has option to add maps to the site using google maps api. I found hundreds of tutorial and blog posts on embeding map in the site. But what I actually want is a way to give the user choose a place on the map and add marker. Then get the co-ordinates of the marker and store it in the database of retrieving and showing in the front-end. I have seen this option given wordpress plugins like mappress. But now I'm trying to achieve this in codeigniter. I can't find any thing to start on. Can any one point out some one tell me where to start?
This is really easy the 3rd version of the Google maps API. Versions before that where much more complicated, and most of the tutorials floating around are for those versions. Have a look through the API documentation and examples.
Adding a marker is as simple as:
var marker=new google.maps.Marker({/* ... see API */});
Adding an event (eg click) to a marker is as simple as:
var marker_click=new google.maps.event.addListener(
marker,
'click',
function() {/*...*/});
Sounds like you'd want a click event for the map, which you'd translate into a latlong, then (a) generate a marker on the map with JS, and (b) post that back to your server using AJAX, or by storing the values in a hidden form field to be submitted after.
Update:
Mostly from the API documentation # http://code.google.com/apis/maps/documentation/javascript/events.html:
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var myOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
});
}
function placeMarker(location) {
var clickedLocation = new google.maps.LatLng(location);
var marker = new google.maps.Marker({
position: location,
map: map
});
map.setCenter(location);
/*Do your processing here:
* eg. ajax.post('addMarkerDB&lat='+location.lat+'&long='+location.long);
*/
}
Note: There is no ajax.post function by default, but there could be :)
