Save the page as
ch8_example1.html
and load it into your browser.
The page requires the user's consent in order to retrieve his or her geographical position. So the
first thing you will see is a prompt asking you to allow or deny the page permission to retrieve that
information. Every browser displays this request differently; Figure 8-3 is Chrome's request.

If you allow the page to access your position, you'll see the latitude and longitude of your device or
computer displayed in an
alert
box. If you choose to deny access, you'll see a message similar to that
shown in Figure 8-4.
