3  To start retrieving location information, you need to create a location watch
4  by calling $(ref:location.watchLocation), passing in
5  the location watch details via the <code>requestInfo</code> parameter:
6</p>
7
8<pre>chrome.location.watchLocation(name, requestInfo);</pre>
9<p>
10  You also need to add a listener
11  for the $(ref:location.onLocationUpdate) event.
12  Chrome will fire this event after you create your location watch, and
13  it will keep firing the event every time the geographic
14  location of the host machine changes, until you call $(ref:location.clearWatch).
15</p>
16<p>
17  Here's sample code
18  to listen for location updates:
19</p>
20<pre>
21  chrome.location.onLocationUpdate.addListener(function(position) {
22    console.log(JSON.stringify(position));
23  });
24</pre>
