Overview of this book

jQuery is used by millions of people to write JavaScript more easily and more quickly. It has become the standard tool for web developers and designers to add dynamic, interactive elements to their sites, smoothing out browser inconsistencies and reducing costly development time.jQuery Hotshot walks you step by step through 10 projects designed to familiarise you with the jQuery library and related technologies. Each project focuses on a particular subject or section of the API, but also looks at something related, like jQuery's official templates, or an HTML5 feature like localStorage. Build your knowledge of jQuery and related technologies.Learn a large swathe of the API, up to and including jQuery 1.9, by completing the ten individual projects covered in the book. Some of the projects that we'll work through over the course of this book include a drag-and-drop puzzle game, a browser extension, a multi-file drag-and-drop uploader, an infinite scroller, a sortable table, and a heat map. Learn which jQuery methods and techniques to use in which situations with jQuery Hotshots.

Prepare for Lift Off

In the last task we used Google's trigger() method to trigger a custom event each time a new marker was added to the map following a click. In this task we'll add a handler for that custom event.

So far in this project, we've stuck almost entirely to Google's map API and haven't really used jQuery at all other than to add the initial document.load wrapper for the rest of code. In this part of the project we'll rectify that and fire up jQuery in order to update our UI.

Engage Thrusters

The handler for our custom locationAdd event should be as follows, which...
