I just meant you could use something similar to how I printed the information on the page but instead use it within a form tag. So instead of <code><p>Latitude: ' + position.coords.latitude + '</p></code> maybe you could do something like <code><input type="hidden" name="latitude" value="' + position.coords.latitude + '" /></code> within an HTML form.

That form can have a lookup button to submit the form that would then send the hidden field lat/lon data to your server. You could then use that to do whatever database lookups you need. @erik, You can use the javascript techniques I’ve shown to populate hidden form fields.

You could include it in a form field (even a hidden field) that the user submits with other form data. Or you could use AJAX to send it back to your site in real time without other user action. For looking up the nearest city, etc., you want what is called <em>reverse geocoding</em> Try Googling that term to learn more about it. Here's a page with a few <a href="http://groups.google.com/group/Google-Maps-API/web/resources-non-google-geocoders?version=56&pli=1" rel="nofollow">reverse geocoding links</a> to help get you started.

Tried it on my site and I was able to display Long/Lat/Alt/Speed/etc. from my iPhone and Android. Can you point me to services where I can translate this data into usable info like City/State so I can use it on my website? Also, how can my site grab this info? Thanks! Great code.

However, my iphone seems to cache the location regardless of the maximum age value I pass. This means my app can show its last stored located for up to 10 minutes after I have switched my iphone on - unless I open google maps, in which case it refreshes the location. Anyone else experience this? Thanks for this, got it working in a web app I am developing. However, my iphone seems to cache the location regardless of the maximum age value I pass.
