Display a Popup on Click
Showing a popup on any map click requires listening to the map’s click event and using the event’s lngLat property to position a new Popup at the cursor’s geographic coordinates. The popup is removed before a new one is created so only one is visible at a time. Use this pattern as the foundation for coordinate pickers, location inspectors, or any tool where clicking the map should reveal information about that point.

map.addControl(new maptoolkit.NavigationControl(), 'top-right');
