Asha 305,306,311 are S40 device with new full touch UI which will provide a better user experience for map operation.And developers may not construct ScaleBar and ZoomBar for user.But these devices only support HTML 4.0,Developers can only use Nokia Map API for Web to display map in Browser or Widget. This is a simple Nokia map example with TypeSelector.

<script type="text/javascript" charset=UTF-8"
<style type="text/css">
html {
body {
margin: 0;
padding: 0;
overflow: hidden;
#mapContainer {
width: 100%;
height: 100%;
left: 0;
top: 0;
position: absolute;
<body >
<div id="mapContainer"></div>
<script type="text/javascript">
var mapContainer = document.getElementById("mapContainer");
var map = new nokia.maps.map.Display(mapContainer, {
components: [
new nokia.maps.map.component.Behavior(),
new nokia.maps.map.component.TypeSelector()

After run,the TypeSelector may extend un-completely.


Because these 3 Asha devices's portrait screen width is less than width of horizontal extending TypeSecector.Maybe many developers don't think it's a questioin because user can rotate to landscape screen which has full width and is fit for 2 hands hold.But I think developers had better provide users another convenience way which let them operate map when only can use single hand.

So the newer version of Nokia Map API for Web is introduced to settle this question,only alter another Javascript file.

<script type="text/javascript" charset=UTF-8"

And the TypeSecector will extend vertical,


which is not only fit for 3 Ashas but also many other limited screen devices .

Way above is good but I prefer next which via increasing the width of the map container.

<script type="text/javascript" charset=UTF-8"
#mapContainer {
width: 150%;

The TypeSelector dosn't appear first


before user drag mapcontainer from right to left.


The TypeSelector can extend horizontal completely,


and be draged,selected or closed.
