Google Maps: Additional Libraries can load inside of MapThe JavaScript code for the Maps API is loaded via a bootstrap URL of the form http://maps.google.com/maps/api/js. This bootstrap request loads all of the main Javascript objects and symbols for use in the Maps API. Some Maps API features are also available in self-contained libraries which are not loaded unless you specifically request them. Breaking up supplemental components into libraries allows the main API to load (and parse) quickly; you only incur the additional overhead of loading and parsing libraries if you need them. You specify additional libraries to load within the bootstrap request by specifying a libraries parameter, passing that parameter the name of the library or libraries. Multiple libraries may be specified as a comma-separated list. Once loaded, libraries are accessed via the google.maps.libraryName namespace. The following libraries are currently available:
We will add more libraries in the future as we release additional opt-in features. The following bootstrap request illustrates how to request the google.maps.geometry library of the Maps Javascript API: <script type="text/javascript" src="http://maps.google.com/maps/api/js?libraries=geometry&sensor=true_or_false"> </script> |
