Geolocation API and Client-Side Maps Frameworks

Geolocation API and Client-Side Maps Frameworks

During the wrap up of the HTML5 course that Geolocation API and Maps FrameworksI’m currently co-authoring, I’ve created two examples of using Geolocation API with Google Maps and with Bing Maps (I didn’t want to deprive any of them Smile). This post won’t introduce the frameworks or the APIs. On the other hand try to find the differences of doing almost the same thing in both of the client-side maps frameworks.
