Google Maps JavaScript API Cookbook

Overview of this book

Day by day, the use of location data is becoming more and more popular, and Google is one of the main game changers in this area. The Google Maps JavaScript API is one of the most functional and robust mapping APIs used among Geo developers. With Google Maps, you can build location-based apps, maps for mobile apps, visualize geospatial data, and customize your own maps.Google Maps JavaScript API Cookbook is a practical, hands-on guide that provides you with a number of clear, step-by-step recipes that will help you to unleash the capabilities of the Google Maps JavaScript API in conjunction with open source or commercial GIS servers and services through a number of practical examples of real world scenarios. This book begins by covering the essentials of including simple maps for Web and mobile, adding vector and raster layers, styling your own base maps, creating your own controls and responding to events, and including your own events.You will learn how to integrate open source or commercial GIS servers and services including ArcGIS Server, GeoServer, CartoDB, Fusion Tables, and Google Maps Engine with the Google Maps JavaScript API. You will also extend the Google Maps JavaScript API to push its capabilities to the limit with additional libraries and services including geometry, AdSense, geocoding, directions, and StreetView.This book covers everything you need to know about creating a web map or GIS applications using the Google Maps JavaScript API on multiple platforms.

Creating your own events


Events are very important for JavaScript programming, and all JavaScript frameworks and APIs give developers access to some predefined event types related to their classes. The Google Maps JavaScript API is doing the same, and it gives us the most used event types with their classes. But what if you need a custom event type?

The Google Maps JavaScript API has a base class named google.maps.MVCObject that is the top class that most of the classes inherit. The class is ready for using in custom events with the google.maps.event namespace.

In this recipe, we will create a custom object with the google.maps.MVCObject class and bind it to a custom event to create your own events. The usage of the custom event cannot be a real-world case, but it will give you an idea about listening and firing your own events.

Getting ready

This recipe is still using the same map creation process defined in Chapter 1, Google Maps JavaScript API Basics, but there are some additional code blocks...
