Can iPhone web apps get GPS position?

Question

Is there an easy way to design a website to facilitate an iphone user providing gps coordinates to the site?

I am wondering if there might be a naming convention for form fields for example, to let the user input in an automated way.

I am considering building a location based website and would like to tailor it for iphone (and other mobile users). I realize an iphone app could do this but I'm not equipped to create one.

Answer 1

Here's a snippet on how to read location from the iPhone. Looks like it requires 3.0:

 navigator.geolocation.getCurrentPosition(foundLocation, noLocation);

 function foundLocation(position)
 {
   var lat = position.coords.latitude;
   var long = position.coords.longitude;
   alert('Found location: ' + lat + ', ' + long);
 }
 function noLocation()
 {
   alert('Could not find location');
 }

By the way, if you want to use web code on the iPhone, there are a couple middle-ground solutions you could try that don't force you to create a native app but allow you to wrap your site in an app and get access to GPS and other native features.

Check out the app SendLocation under navigation by Jouni Erola.

Its a simply app that will send out the lat & lon of the iPhone to YOUR server. Simply enter your server url to receive the location as HTTP-GET methid
