<h1>Map Objects Event Delegation</h1>
<p>Use event delegation on map objects</p>
</div>
<p>This example shows how to use a single function to listen to the <code>tap</code> event across multiple map objects held within the same object container.</p>
<div id="map"></div>
<h3>Code</h3>
<p>All <code>H.map.Object</code> elements such as a marker or polygon, along with the
<code>H.map.Group</code> container class implement the <code>addEventListener()</code>
method, which is used when attaching an event listener.</p>
<p>When a <code>tap</code> event occurs, the fired event is an instance of the <code>H.util.Event</code>
class and therefore contains a <code>target</code> property which is the map object clicked.</p>
