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.

<title>Map Features</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript"
src="http://api.maps.nokia.com/2.2.4/jsl.js" charset="utf-8">
</script>
</head>
<body>
 
<div id="mapContainer" style="z-index: -1; left:0px; top:0px; width: 100%; height: 80%; position: absolute;"></div>
<script type="text/javascript">
/////////////////////////////////////////////////////////////////////////////////////
// Don't forget to set your API credentials
//
// Replace with your appId and token which you can obtain when you
// register on http://api.developer.nokia.com/
//
nokia.Settings.set( "appId", "YOUR APP ID GOES HERE");
nokia.Settings.set( "authenticationToken", "YOUR AUTHENTICATION TOKEN GOES HERE");
 
//
/////////////////////////////////////////////////////////////////////////////////////
 
// This example will first display the full Feature Map components and then of those what
// are being used in the current map that is loaded and in use.
 
var map;
map = new nokia.maps.map.Display(document.getElementById("mapContainer"),
{
components: [ new nokia.maps.map.component.Behavior(),
new nokia.maps.map.component.ZoomBar(),
new nokia.maps.map.component.Overview(),
new nokia.maps.map.component.TypeSelector(),
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");
}
</script>
</body>
</html>
