CHAPTER 7 ■ INFOWINDOW TIPS AND TRICKS Figure 7-1. The base map as it will look in <strong>Google</strong> Chrome Style Sheet The style sheet provides some basic styling (Listing 7-2). What’s different from the previous examples is that the map will span the whole page. Worth mentioning is that to make this work across most browsers, the height must be set to 100 percent for the HTML, body, and map. Listing 7-2. The CSS html, body { height: 100%; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: small; margin: 0; } #map { width: 100%; height: 100%; } 132
CHAPTER 7 ■ INFOWINDOW TIPS AND TRICKS JavaScript The JavaScript creates a map and adds a marker with a click event to it (Listing 7-3). Listing 7-3. The Initial JavaScript (function() { // Defining variables that need to be available to some functions var map, infoWindow; window.onload = function() { }; })(); // Creating a map var options = { zoom: 3, center: new google.maps.LatLng(37.09, -95.71), mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById('map'), options); // Adding a marker var marker = new google.maps.Marker({ position: new google.maps.LatLng(40.756054, -73.986951), map: map, title: 'Click me' }); google.maps.event.addListener(marker, 'click', function() { // Code that happens after click }); With the base set, you can move on to the examples. Adding Rich Content to the InfoWindow In Chapter 5, you looked at some basic usage of InfoWindows. You looked at how to create them and how to fill them with basic text. Now you’re going to take this one step further by adding full HTML to them. There’s nothing magical about InfoWindows; they’re really just HTML containers. Think of them as just another part of the web page. And just like all other parts of a web page, you can fill this part with whatever content you like. There are two ways of adding content to an InfoWindow. The first, and perhaps most straightforward way, is to provide an InfoWindow with a string that contains all the HTML. The other way is to provide it with a reference to an existing HTML node. This HTML node can either already exist in the document or be one that you create with JavaScript. In this first example, you’re going to add content to an InfoWindow using a string. 133
