Building Web and Mobile ArcGIS Server Applications with JavaScript ??? Second Edition - Second Edition

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.

There are four different toolbars that you can add to your application using helper classes provided by the API. The two we'll talk about in this chapter are Navigation and Draw. There is also an editing toolbar that can be used to edit features or graphics through a web browser. We'll discuss this toolbar in a later chapter. Bear in mind that when we talk about "toolbars" here, we are referring to the helper classes that assist you in building such toolbars, and not the toolbars themselves. The look and feel of your toolbar is down to you.

Note

Note that the API includes another toolbar which provides support for measuring image services. That is beyond the scope of this book.

Steps for creating a toolbar

The navigation and draw toolbars are not simply user interface components that you can drop into your application. They are helper classes and there are several steps that you need to take to actually create your toolbar with the appropriate buttons. This...
