When geocoding over 11 locations using the Google Maps API v3, you may encounter the OVER_QUERY_LIMIT error. This indicates that you are exceeding the rate limit for geocoding requests.
To resolve this error, you need to introduce pauses between geocoding requests.
Here is a modified version of your code that implements a pause after each geocoding request:
<code class="javascript">function codeAddress(vPostCode) { if (geocoder) { setTimeout(function() { geocoder.geocode( { 'address': "'" + vPostCode + "'"}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); }, 2000); // 2 seconds delay } }</code>
In this code, the setTimeout() function is used to introduce a delay of 2 seconds (2000 milliseconds) between each geocoding request. This ensures that you do not exceed the rate limit imposed by the API.
