This article features an example on how to read, display and load Map Features
Contents |
Introduction
This example uses the Nokia Maps API Feature manipulation functionality, described in the API Reference here:
http://developer.here.net/docs/maps_js/topics_api_pub/nokia.Features.html
Please check it out for detailed description on the subject.
Prerequisites
Nokia Maps API supported web browser (basically any modern web browser will do).
Example code
This example loops through and displays all supported features/sets and features of the current map. It also attempts to load features and handles success and failure, and in this example the load should be a success.

new nokia.maps.map.component.ScaleBar() ],
zoomLevel: 4,
center: [52.51, 13.4] // default map center point (not the location retrieved)
});
//Retrieve Feature Map
var list = nokia.maps.Features.getFeatureMap();
// Loop through the features and show them in an alert
// Returns a map of implementations for each registered feature.
for( var i in list )
{ if ( list.hasOwnProperty(i) )
alert("Feature Map: "+list[i]);
}
// Retrieve Loaded Map
var list = nokia.maps.Features.getLoadedMap();
// Loop through the features and show them in an alert
// Returns a map of the names of fully loaded feature implementations per feature.
for( var i in list )
{ if ( list.hasOwnProperty(i) )
alert("Loaded Map:" +list[i]);
}
nokia.maps.Features.load({"map": "auto", "routing": "auto"}, load_Successful, load_Failed);
nokia.maps.Features.load({"map": "auto", "search": "auto"}, load_Successful, load_Failed);
function load_Successful(result){
alert("SUCCESSFUL FEATURE LOADING");
}
function load_Failed(result){
alert("FEATURE LOADING FAILED");
}
