Introduction

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)


Prerequisites

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

Important 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 Location API Business Models and Usage Restrictions 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 from the Nokia Developer API Registration page.

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.

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.

var infoBubbles = new nokia.maps.map.component.InfoBubbles();
map.addComponent( infoBubbles);

The function described below, will add an onclick event to a marker and display the associated HTML content.

function addInfoBubble(infoBubbles, marker, html) {
marker.html = html;
marker.addListener("click" , function(evt) {
infoBubbles.addBubble(evt.target.html, evt.target.coordinate);
}, false);
}

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

var marker;
var markers = new Array();
marker = new nokia.maps.map.StandardMarker(new nokia.maps.geo.Coordinate(53.4393381986981,-2.2211828827858));
addInfoBubble( infoBubbles, marker, "<div><a href='http://www.mcfc.co.uk' >Manchester City</a></div><div >City of Manchester Stadium<br>Capacity: 48,000</div>");
markers.push(marker);
marker = new nokia.maps.map.StandardMarker(new nokia.maps.geo.Coordinate(53.4308166986509,-2.96082615852356));
addInfoBubble( infoBubbles, marker, "<div ><a href='http://www.liverpoolfc.tv' >Liverpool</a></div><div >Anfield<br>Capacity: 45,362</div>");
markers.push(marker);
map.objects.addAll(markers);
