Which web browsers (and version) support Gelocation via HTML5?
Assuming you mean geolocation API's,
Firefox: https://developer.mozilla.org/En/Using_geolocation
Opera: http://my.opera.com/core/blog/geolocation-enabled-build
And more about it here: http://en.wikipedia.org/wiki/W3C_Geolocation_API
on the desktop only firefox (not sure if opera already includes it in official builds), on mobile: mobile safari 3 & android 2.x browser
more info about support on:
- the desktop: http://www.findmebyip.com/litmus
- mobile: http://www.quirksmode.org/webkit.html#t013
hope this helps, frank
Geolocation on Safari is iPhone only
Google Chrome beta has optional support: http://www.wait-till-i.com/2010/03/04/google-chrome-getting-navigator-geolocation/
Unfortunately Opera 10.50 does not seem to have geolocation, which is a bit of bummer considering how great it looks in most other regards. (Video, audio, CSS3 improvements + Carakan really smokes V8, Squirrelfish and Tracemonkey.)
