Introduction
When the user clicks the mouse right button, a RightClick event takes place. The Nokia Maps API there is certain functionality that can be attached to it and the opening menu.
In this example we will add Routing Component and the Search component.
map.components.add(myRightClick); map.components.add(myRoutingComponent); map.components.add(mySearchComponent);
These can be then bound to further parts of your program to provide additional functionality.
Prerequisites
Nokia Maps API supported web browser (basically any modern web browser)
Important about Maps credentials
With Nokia Maps API you can start without having any credentials given, but you might face a performance gap. In order to get the full potential out of the offering, you must get the credentials that authenticate your application against the Services. Please read through the Location API.
For more information on how to obtain the credentials, please start with the Nokiai Maps API Developers Guide section "Acquiring API credentials"
Implementation
In the example we will add a RightClick() component to the map, then populate it with Routing and Search.
