iPhone - GeoLocation

ironclaw

Hi Folks,

I'm looking for a good way to show a map with the users posiotion highlighted in iPhone. I have limited experience with Java which seems to be the way to call.

The script I found at the moment is this:

<script>
function handler(location) {
var message = document.getElementById("message");
message.innerHTML ="<img src='http://maps.google.com/staticmap?center=&quot; + location.coords.latitude + "," + location.coords.longitude + "&size=300x200&maptype=map&zoom=16&key=GoogleAPIKey' />";
message.innerHTML+="<p>Longitude: " + location.coords.longitude + "</p>";
message.innerHTML+="<p>Latitude: " + location.coords.latitude + "</p>";
message.innerHTML+="<p>Accuracy: " + location.coords.accuracy + "</p>";
}
navigator.geolocation.getCurrentPosition(handler);
</script>

It works really well. However, is there anyway to take the variables of Longitude and Latitude, and place them in a form field automatically? i.e. To upload your location?

Thanks,

ironclaw.

That's Javascript not Java ...

Yes, you can add the location.coords.longitude (or any other var value) to any other HTML element. There you chose to incorporate them to the innerHTML of the element with the id "message". If you have a form element (like an input with type="text"), you can assign anything to its value property. That's the way to go if you want to assign anything to an element of a form.
