Google Maps API - how to get latitude and longitude from Autocomplete without showing the map?

autocomplete, google-maps-api-3, javascript, latitude-longitude

Solution

You can use the code below.

<script src="http://maps.googleapis.com/maps/api/js?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.addListener(autocomplete, 'place_changed', function () {
            var place = autocomplete.getPlace();
            document.getElementById('city2').value = place.name;
            document.getElementById('cityLat').value = place.geometry.location.lat();
            document.getElementById('cityLng').value = place.geometry.location.lng();
            //alert("This function is working!");
            //alert(place.name);
           // alert(place.address_components[0].long_name);

        });
    }
    google.maps.event.addDomListener(window, 'load', initialize); 
</script>

and this part is inside your form:

<input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on" runat="server" />  
<input type="hidden" id="city2" name="city2" />
<input type="hidden" id="cityLat" name="cityLat" />
<input type="hidden" id="cityLng" name="cityLng" />
