Overview of this book

The ArcGIS API for JavaScript enables you to quickly build web and mobile mapping applications that include sophisticated GIS capabilities, yet are easy and intuitive for the user. Aimed at both new and experienced web developers, this practical guide gives you everything you need to get started with the API. After a brief introduction to HTML/CSS/JavaScript, you'll embed maps in a web page, add the tiled, dynamic, and streaming data layers that your users will interact with, and mark up the map with graphics. You will learn how to quickly incorporate a broad range of useful user interface elements and GIS functionality to your application with minimal effort using prebuilt widgets. As the book progresses, you will discover and use the task framework to query layers with spatial and attribute criteria, search for and identify features on the map, geocode addresses, perform network analysis and routing, and add custom geoprocessing operations. Along the way, we cover exciting new features such as the client-side geometry engine, learn how to integrate content from ArcGIS.com, and use your new skills to build mobile web mapping applications. We conclude with a look at version 4 of the ArcGIS API for JavaScript (which is being developed in parallel with version 3.x) and what it means for you as a developer.

Introduction to HTML, CSS, and JavaScript

There are certain fundamental concepts that you need to understand before you can get started with developing GIS applications with the ArcGIS API for JavaScript. For those of you already familiar with HTML, JavaScript, and CSS you may wish to skip ahead to the next chapter. However, if you're new to any of these concepts read on. We are only going to cover these topics at a very basic level. Just enough to get you started. For a more advanced treatment of any of these subjects there are many learning resources available including books and online tutorials. Please consult Appendix for a more comprehensive list of these resources.

In this chapter we will cover the following topics:
