title: Google maps places autocomplete loading events
body: <p>I'm using the <a href="https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete">Google Maps Places Autocomplete</a> api.</p>
  
  <p>I would like to show an Ajax spinner during the search, before the autocomplete dropdown is displayed.</p>
  
  <p>How can I determine when the places results are ready? Is there some event fired off?</p>
  
  <p>This is particularly helpful on bad internet connections since the latency can sometimes be up to 5 seconds. The user needs to know the search box is an autocomplete inputbox before frantically pressing enter to search.</p>
