I'm so excited that Google Map API has released a new version, and I don't need the API Key anymore. I'm going to have a good time playing with this. The following is the specific report:
According to the Google Geo Developers Blog, about 0.15 million active websites are using this API since the JavaScript-based Google Maps API was released three years ago, google Maps API has become the most popular and reliable network development tool. Now, Google map API has been significantly revised, users can now use the third-edition map API application in Google Code Labs.
The main feature of the new version of the API is to increase the speed, especially for the rendering speed of mobile browsers. Last year, Google began to think about the feasibility of running the map API on mobile devices, with the launch of powerful and complete browsers for iPhone and G1, it is possible to port the second version of map API on the Web to a mobile browser, but there are many restrictions on the second version of API, therefore, Google launched the third-edition map API program.
To enable users to use the third-edition API as soon as possible, Google has released its basic functions in the lab. Click here to view the documentation. Of course, all the functions are not fully developed, users can provide some feedback on their use. Users can use the third-edition API to improve the user browsing experience without rewriting the old mashup code.
APIS of the third edition have the following functions:
1. Supports Chrome, iPhone Safari, and Android phones.
2. You do not need API keys, so that you can integrate the code into the RSS reader without any errors.
3. Based on the Model-View-Controller framework, this reduces JavaScript downloads and is easy to use.
4. Enable the default UI and provide the default UI controls and methods. This allows the user to automatically update the UI to the latest format. Of course, you can disable this function.
5. namespace. Everything is in the namespace of Google. Maps. *, and there is no global variable prefixed with "G.
6. geocoding API has been rewritten based on user feedback.
