title: Is there a way to know if geolocation is enabled for the current domain?
body: <p>The website I'm working on uses HTML5 geolocation api. It works fine, but I need to know if the feature has been authorized.<br>
  <code>navigator.geolocation</code> only tells if the feature is available. What I want to know is whether the user has enabled it already. Basically, I need to know if the browser will request permission to use the feature. Is it possible?</p>
