Retrieving Autocomplete Predictions

This example executes a query prediction request for the phrase "pizza near Syd" and displays the results as an HTML list.

Read the documentation.

// This example retrieves autocomplete predictions programmatically from the
// autocomplete service, and displays them as an HTML list.

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">

function initService() {
  var displaySuggestions = function(predictions, status) {
    if (status != google.maps.places.PlacesServiceStatus.OK) {
      alert(status);
      return;
    }

    predictions.forEach(function(prediction) {
      var li = document.createElement('li');
      li.appendChild(document.createTextNode(prediction.description));
      document.getElementById('results').appendChild(li);
    });
  };

  var service = new google.maps.places.AutocompleteService();
  service.getQueryPredictions({ input: 'pizza near Syd' }, displaySuggestions);
}
<div id="right-panel">
  <p>Query suggestions for 'pizza near Syd':</p>
  <ul id="results"></ul>
