An infoBubble must have a nokia.maps.geo.Coordinate and content which can be either provided as a string or as a nokia.maps.search.Location object.

API defines:

Extends nokia.maps.map.component.Component.
new nokia.maps.map.component.InfoBubbles ()
Options Interface defining the info bubbles' options (keys)


HERE Maps API supported web browser (basically any modern web browser)

Important note about maps credentials

Nokia provides several services options within the Maps API offering. The service is free to use, but you must obtain and use authentication and authorization credentials to use the services. Please read the Terms and Conditions and check the Pricing Plans page to decide which business model best fits your needs. Authentication requires unique Maps API credentials, namely an AppId and a token. You can get these credentials free for free following the instructions here

Adding an Infobubble directly onto the Map

In this example we will create one infoBubble with video content from YouTube. Location is mumbai, where a info bubble would be shown with out youtube video. Remember to add in your own AppId and Token.

function addInfoBubble(map){
map.set("baseMapType", map.SATELLITE);
map.set("center", new nokia.maps.geo.Coordinate(19.119, 72.8957));
var infoBubbles = new nokia.maps.map.component.InfoBubbles();
var myHTMLcontent = "<div class=\"myHtmlContent\">"+"<iframe width='425' height='349' " +
" src='http://www.youtube.com/embed/Nr41eRzUnrg' frameborder='0' allowfullscreen>" +
new nokia.maps.geo.Coordinate(19.119, 72.8957)) ;


A fully working example can be found at:


Adding an InfoBubble to a map marker

Assuming we already have a map, the first thing to do is to create an info bubble and add it as a map component, and a container with an onclick event

var infoBubbles = new nokia.maps.map.component.InfoBubbles();
container = new nokia.maps.map.Container();
container.addListener("click" , function(evt) {
infoBubbles.openBubble(evt.target.html, evt.target.coordinate);
}, false);

The function described below, will add a marker and HTML content to the container

function addMarkerToContainer(container, coordinate , html) {
var marker = new nokia.maps.map.StandardMarker(
coordinate, {html: html});

Finally the markers themselves must be added. Clicking on the marker brings up the embedded HTML.

addMarkerToContainer(container, [53.439,-2.221], 
"<div><a href='http://www.mcfc.co.uk' >Manchester City</a>" +
"</div><div >City of Manchester Stadium<br>Capacity: 48,000</div>");
addMarkerToContainer(container, [53.430,-2.961],
"<div ><a href='http://www.liverpoolfc.tv' >Liverpool</a>" +
"</div><div >Anfield<br>Capacity: 45,362</div>");



Working Example:


Pre-opening an InfoBubble

It is possible to use the dispatch() method, to fire an onclick event, which causes the infobubble to be opened when the page is loaded. Image a URL of the form ../open-infobubble-with-id.html?id=2 - the query string of this url can be read to determine which infobubble should be opened.

First create a helper function to obtain the query string parameters:

function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));

The call the function below to open the relevant id

function openInfoBubble(){
var param = getParameterByName('id');
if (param == ""){
return; // Don't open a bubble.
// Iterate through the markers to find the correct id.
for (var i = 0; i < container.objects.getLength(); i++){
if (param === container.objects.get(i).id){
// fire an event to open the bubble.
new nokia.maps.dom.Event(
{type: "click",
target: container.objects.get(i)}));

The markers must be assigned a unique id when instantiated as shown:

var marker = new nokia.maps.map.StandardMarker(
new nokia.maps.geo.Coordinate(52.516237, 13.377686),
{html: "Brandenburger Tor",
id : "1" }
var fernsehturmMarker = new nokia.maps.map.StandardMarker(
new nokia.maps.geo.Coordinate(52.520816, 13.409417),
{html: Fernsehturm,
id : "2" }
