I am using google autocomplete places javascript to return suggested results for my searchbox , what I need is to only show the city and the country related to the characters entered but google api will give a lot of general places results which I dont need , so how to limit the result to show only city and the country .

I am using the following Example:

<html>
<head>
<style type="text/css">
   body {
         font-family: sans-serif;
         font-size: 14px;
   }
</style>

<title>Google Maps JavaScript API v3 Example: Places Autocomplete</title>
<script src="http://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places" type="text/javascript"></script>
<script type="text/javascript">
   function initialize() {
      var input = document.getElementById('searchTextField');
      var autocomplete = new google.maps.places.Autocomplete(input);
   }
   google.maps.event.addDomListener(window, 'load', initialize);
</script>

</head>
<body>
   <div>
      <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on">
   </div>
</body>
</html>

答案 1

You can try the country restriction

function initialize() {

 var options = {
  types: ['(cities)'],
  componentRestrictions: {country: "us"}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

More info:

ISO 3166-1 alpha-2 can be used to restrict results to specific groups. Currently, you can use componentRestrictions to filter by country.

The country must be passed as as a two character, ISO 3166-1 Alpha-2 compatible country code.

Officially assigned country codes
