Is javascript geolocation inside an html5 page calculated different for each mobile browser?

Question

If I insert the following code into an html5 page will the geolocation work on safari ios, android and blackberry browsers?

getViaHtml5 = function(done) {
 if(navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(function(position) {
  vicinity.lat = position.coords.latitude;
  vicinity.lng = position.coords.longitude;
  done();
 }, function(e) {
  console.warn('ERROR(' + e.code + '): ' + e.message);
  });
 } else {
  console.warn("Browser doesn't support Geolocation");
 }
};

I'm not asking if the actual code is correct. I'm asking if javascript geolocation on an html5 page will work for the various mobile browsers or is there a different method for each browser (safari ios, android and blackberry browsers)

Answer 1

there are two methods: the html5 geolocation api, and polyfill(s) for the rest.
android, and mobile safari are good to go; i actually had to look up blackberry, but you're good:

depending on what version(s) of IE you support, modernzr handles IE8 and up.
If you need below IE8 use this geolocation fallback library:
