Is there any way to fix this error 'google is not defined'

I'm using distant matrix and places api to calculate the distance between places and suggestions , I'm using a script on the index blade shows 'google is not defined'

 function initialize() {
      var input = document.getElementById('searchloc');
      var options = {
        types: ['geocode'], //this should work !
        componentRestrictions: {country: "ae"}
      };
      var autocomplete = new google.maps.places.Autocomplete(input, options);     
}
   google.maps.event.addDomListener(window, 'load', initialize);
