The ClusterLayer constructor works fine but I want to change what pins are on the ClusterLayer later in the code. setPushpins() seems like the desired function here but I am getting an Uncaught TypeError: Cannot read property '_v8Map' of undefined. This is a sample of what I have so far
window.map = new Microsoft.Maps.Map("#map_canvas",
{credentials:maps_key,
enableSearchLogo:false,
showCopyright:false,
mapTypeId:Microsoft.Maps.MapTypeId.road,
zoom:4,
scrollwheel:true,
center:new Microsoft.Maps.Location(us_latitude, us_longitude)
});
Microsoft.Maps.loadModule("Microsoft.Maps.Clustering", function(){
//Generate 1,000 random pushpins in the map view.
//var pins = Microsoft.Maps.TestDataGenerator.getPushpins(1000, map.getBounds());
var pins = [];
var latitude = 43;
var longitude = -120;
var loc = new Microsoft.Maps.Location(latitude, longitude);
pin = new Microsoft.Maps.Pushpin(loc);
pins.push(pin);
//Create a ClusterLayer and add it to the map.
var loc = new Microsoft.Maps.Location(latitude+10, longitude+10);
pin = new Microsoft.Maps.Pushpin(loc, options);
pins.push(pin);
var clusterLayer = new Microsoft.Maps.ClusterLayer(pins);
map.layers.insert(clusterLayer);
clusterLayer.setPushpins(pins);
});
How should I go about changing which pins are part of a ClusterLayer?
Testing the setPushpins function I do see the error you are seeing. Interestingly after ignoring the error message the clusteringLayer adds the pushpins and works fine. I'll have the team look into why this error is being thrown.

Hi I'm using bing maps v8. I have 2 default layers with pushpins. By default only the last added layer gets displayed on map. I have made the layer1 visible using setVisible function, Still it doesn't show up on the map. Is it existing but not showing up. I'm not sure why its overlapping. Its same with many layers.
This is the code resembles somethis like this
var pushpin = new Microsoft.Maps.Pushpin(map.getCenter(), null);
var layer1 = new Microsoft.Maps.Layer();
layer1.add(pushpin);
map.layers.insert(layer1);
var pushpin2 = new Microsoft.Maps.Pushpin(map.getCenter(), null);
var layer2 = new Microsoft.Maps.Layer();
layer2.add(pushpin2);
map.layers.insert(layer2);
You pushpins are in the exact same location. Both are rendered, but the one in layer1 is completely covered by the one that is in layer2, so you can't see it.
Here is a simple code sample to test. Simply copy and paste it into the edit window here: http://www.bing.com/api/maps/sdk/mapcontrol/isdk#addOneLayerItem+JS
var map = new Microsoft.Maps.Map(document.getElementById('myMap'), {
credentials: 'Your Bing Maps Key'
});
var pins = Microsoft.Maps.TestDataGenerator.getPushpins(3, map.getBounds());
var layer1 = new Microsoft.Maps.Layer();
layer1.add(pins [0]);
map.layers.insert(layer1);
var layer2 = new Microsoft.Maps.Layer();
layer2.add(pins [1]);
map.layers.insert(layer2);
I have a map of bing maps and I use has created pushpin do with double click. And now I want to make limits pushpin only <= 20.
If it has been over the limit point is then automatically pushpin cannot be displayed. Although double click in map.
But I don't understand how to create it. Can you help me? Thanks a lot. Gbu.
My code to show pushpin
map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), mapOptions);
Microsoft.Maps.Events.addHandler(map, 'dblclick',getLatlng );
}
//show pushpin
function getLatlng(e) {
if (e.targetType == "map")
{
var point = new Microsoft.Maps.Point(e.getX(), e.getY());
var locTemp = e.target.tryPixelToLocation(point);
var location = new Microsoft.Maps.Location(locTemp.latitude, locTemp.longitude);
alert(locTemp.latitude + "&" + locTemp.longitude);
var pin = new Microsoft.Maps.Pushpin(location, { 'draggable': false });
map.entities.push(pin);
alert("Done");
Microsoft.Maps.event.addListener(map, 'click', function (event)
{
}
// limit pushpin
*How to create limit pushpin?*
In the getlatlng function you can do a simple check to see how many shapes are on the map. You can get the number of shapes on the map in your application by doing the following:
var cnt = map.entities.getLength();
I am using version 7.0 of the Bing Maps API. After creating the map, an array of pins are pushed into the EntityCollection object of the map class. Next, I want to center the map so that all of these pins are viewed on the map. The map's zoom is large enough to accommodate this. In the previous version, map.setMapView() was used, but BING Maps 7.0 has erased this function.
Some code for relevance:
map = new Microsoft.Maps.Map(document.getElementById("myMap"), mapOptions);
map.getCredentials(function(credentials) {
var searchRequest = 'https://dev.virtualearth.net/REST/v1/Locations/' + address + '?output=json&jsonp=getLatLong&key=' + credentials;
var mapscript = document.createElement('script');
mapscript.type = 'text/javascript';
mapscript.src = searchRequest;
document.getElementById('myMap').appendChild(mapscript);
});
function getLatLong(json){
findPlaceResults = new Microsoft.Maps.Location(json.resourceSets[0].resources[0].point.coordinates[0], json.resourceSets[0].resources[0].point.coordinates[1]);
myShape = new Microsoft.Maps.Pushpin(findPlaceResults);
//...
var pins = new Array();
for (var i = 0; i < AllLocations.length; i++) {
var shape = new Microsoft.Maps.Location(AllLocations[i].Latitude, AllLocations[i].Longitude);
var pins = new Microsoft.Maps.Pushpin(shape);
map.entities.push(pins);
}
map.entities.push(myShape);
if (map.entities.getLength() > 0) {
//map.SetMapView(pins);
}
Code TLDR: Stuff happens, try to SetMapView, doesn't work.
Any thoughts would be helpful!
When you creating your pins you need to create helper array will that lead to your goal.
Create array that contains all the locations converted to Microsoft location objects.
// The array
var arrLocations= [];
for (var i = 0; i < AllLocations.length; i++) {
var shape = new Microsoft.Maps.Location(AllLocations[i].Latitude,AllLocations[i].Longitude);
// You add those two lines.
var yourLocation= new Microsoft.Maps.Location(AllLocations[i].Latitude,AllLocations[i].Longitude);
arrLocations.push(yourLocation);
var pins = new Microsoft.Maps.Pushpin(shape);
map.entities.push(pins);
}
Now you use bing maps feature that gives you best zoom and pointing according to given locations.(The LocationRect)
var bestView = Microsoft.Maps.LocationRect.fromLocations(arrLocations);
Then you set the map view according to the best view that we found.
setTimeout((function () {
map.setView({ bounds: bestView });
}).bind(this), 1000);
Well, I found the answer at this website http://www.i-programmer.info/projects/131-mapping-a-gis/1609-getting-started-with-bing-maps-ajax-control-70.html?start=1
"If you are familiar with earlier versions of the Map object you need to know that the new version has far fewer methods. The idea is that instead of having lots of methods the new control has a few methods that accept complex objects as a parameter that specifies lots of settings.
For example, the original map control's SetCenter method will move the map location to the specified latitude and longitude. The new V7 map control has a setView method which accepts a ViewOptions object which in turn has a center property that can be set to a Location object which specifies the center of the map."
I am creating a map page with a single image,
and I would like to use GeoLocation to show where the user is as a blue dot (somewhat like iOS maps).
I already have the JavaScript for finding the location, and it works great.
I just need help with how to place a marker - just a simple image - on the page according to the output of position.coords.latitude and position.coords.longitude.
Is there any way that this can be done, and if so, how?
Thanks in advance.
You can simply use GMarker in your javascript, something like this:
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!"
});
You can customize its image like that:
var image = 'beachflag.png';
marker.icon = image;
I've an issue with the leaflet openPopup method.
showMap = function(elements) {
var jsonp = 'http://a.tiles.mapbox.com/v3/blahblahblah.jsonp';
var m = new L.Map("my_map").setView(new L.LatLng(51.5, -0.09), 15);
var geojsonLayer = new L.GeoJSON();
var PlaceIcon = L.Icon.extend({
iconSize: new L.Point(25, 41),
shadowSize: new L.Point(40, 35),
popupAnchor: new L.Point(0, -30)
});
var icon = new PlaceIcon(__HOME__ + '/images/leaflet/marker.png');
var marker;
for (var i = 0; i < elements.length; i++) {
var address = $("<div/>").html(elements[i].address).text();
var latlng = new L.LatLng(elements[i].latitude, elements[i].longitude);
marker = new L.Marker(latlng, {icon: icon}).bindPopup(address);
if (i == 0) {
marker.openPopup();
}
m.addLayer(geojsonLayer).addLayer(marker);
}
// Get metadata about the map from MapBox
wax.tilejson(jsonp, function(tilejson) {
m.addLayer(new wax.leaf.connector(tilejson));
});
}
When I click on a marker I have the popup open. But I would like to have the first popup open when the map is loaded. (and open other popups on markers click)
AnNy ideas ?
Put openPopup call after you add the marker to the map and you should be fine.
I'm assuming that when you click on a marker you see the popup but you're not getting the popup of the first marker to show automatically when the map is loaded?
First, it doesn't look like you're actually using GeoJSON so a GeoJSON layer isn't necessary (you can just use a FeatureLayer) but that shouldn't cause any issues. Whatever layer group you use you should only be adding it to the map once and then adding all child layers to the LayerGroup. You're currently adding the geojsonLayer multiple times in your "for" loop which you don't want to do.
Second, you have to call marker.openPopup() after the marker is added to the map.
Try changing your code around to looks something like this:
var layerGroup = new L.FeatureGroup();
layerGroup.addTo( m );
for (var i = 0; i < elements.length; i++) {
var address = $("<div/>").html(elements[i].address).text();
var latlng = new L.LatLng(elements[i].latitude, elements[i].longitude);
marker = new L.Marker(latlng, {icon: icon}).bindPopup(address);
//You don't add the marker directly to the map. The layerGroup has already
//been added to the map so it will take care of adding the marker to the map
layerGroup.addLayer( marker );
if (i == 0) {
marker.openPopup();
}
}
I had this issue and fixed it with adding a timeout right after I added the marker on the map.
marker.addTo(this.map).bindPopup('Info');
setTimeout(() => {
marker.openPopup();
}, 500);
I don't know why but on some page, I need to apply timeout. In any case it's my workaround, hope this works for some of you too.
First add your map then put openPopup():
L.marker([lat, long]).bindPopup('Your message').addTo(map).openPopup();
