title: Is there a way to check if geolocation has been DECLINED with Javascript?
body: <p>I need JavaScript to display a manual entry if geolocation is declined.</p>
  
  <p>What I have tried:</p>
  
  <pre><code>Modernizr.geolocation
  navigator.geolocation
  </code></pre>
  
  <p>Neither describes if user has previously declined access to geolocation.</p>
