Introduction

Ovi Maps API - Getting and setting the default language in application context.

Prerequisites

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

Important about Maps credentials

With Ovi 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 Ovi Maps API Developers Guide section "Acquiring API credentials".

Implementation

This is a full HTML & JavaScript example. Feel free to modify and use for your own purposes.


<html> 
<head>
<script src="http://api.maps.ovi.com/jsl.js" type="text/javascript" charset="utf-8"></script>
<link rel="stylesheet" href="style.css" />
</head>
<div id="map" style="width:100%; height:80%;"></div>
<body style = "width:80%; height:80%;"></div>
</body>
<script type="text/javascript">
// Define the Nokia Maps
var map= new ovi.mapsapi.map.Display(document.getElementById("map"), // new instance of Ovi Maps {
components: [ new ovi.mapsapi.map.component.Behavior(),
new ovi.mapsapi.map.component.ZoomBar(),
new ovi.mapsapi.map.component.Overview(),
new ovi.mapsapi.map.component.TypeSelector(),
new ovi.mapsapi.map.component.ScaleBar()],
'zoomLevel': 4,
'center':[53.1, 13.1] });
 
var appContext = ovi.mapsapi.util.ApplicationContext;
// Go thru all the language options
var availableLanguages = ["en-US", "en-GB", "de-DE", "es-ES", "fr-FR", "it-IT", "ru-RU", "zh-CN"]
//get a random language
var randomLanguageIndex = Math.floor(Math.random() * availableLanguages.length); var randomLanguage = availableLanguages[randomLanguageIndex];
// Get and store the current map default language
var currentLanguage = appContext.get("defaultLanguage");
// Display a note to the user within the document
document.write("The current Default Language is " + currentLanguage);
// Write line break
document.write("<br />");
// Set the default language of the map
appContext.set("defaultLanguage", randomLanguage);
// Get the language we have just set
currentLanguage = appContext.get("defaultLanguage");
// Write the new language
document.write("Now the Default Language is " + currentLanguage);
// Write line break document.write("<br />");
</script>
</body>
</html>
