How do I Use OpenLayers Multi-lingual capabilities?

Question

So, OpenLayers has a i18n namespace.

But in my example at the bottom of the blog.

I am not getting the "Pan Up" which is what I would expect, but instead "PanUp", which is the string that should be translated in en.js.

I don't know enough about how this should work to debug it. I couldn't find much in the documentation about this either.

How does OpenLayers know what language to use? When I switch to French will it know to pull out the translations of "PanUp" from the fr.js file?

Answer 1

Say you want your OpenLayers based map viewer from English to Spanish. The first step is:

OpenLayers.Lang.setCode('es');

To get the translation of 'Base layer' to Spanish:

var translatedString = OpenLayers.i18n('Base layer');

To show the translated string in the layer switcher:

var layerSwitcher = new OpenLayers.Control.LayerSwitcher({'title': translatedString}); map.addControl(layerSwitcher);
