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.

Initializing the map


Getting a zoomable and panable interactive Google map up and running takes a ludicrously small amount of code. In this task we'll add that code, as well as set up some of the variables that we'll use later in the script.

Prepare for Lift Off

In this task we'll initialize the variables needed to configure the map and make a call to the Google Maps API. We should start by adding the standard jQuery wrapper to the empty google-map.js file that we created earlier:

$(function () {
    //all other code in here...
});

Remember, the $(function () { … }); construct is a shortcut for jQuery's document.ready event handler.

Engage Thrusters

Within the wrapper we just added, we should add the following code:

var api = google.maps,
    mapCenter = new api.LatLng(50.91710, -1.40419), 
    mapOptions = {
        zoom: 13,
        center: mapCenter,
        mapTypeId: api.MapTypeId.ROADMAP,
        disableDefaultUI: true
    },
    map = new api.Map(document.getElementById("map"), mapOptions...
