This example creates a request to the geocoding service that restricts the results to a particular postal area within Sydney, Australia.
Read the documentation.
function initMap() {
var geocoder = new google.maps.Geocoder;
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: {lat: -33.865, lng: 151.209}
});
document.getElementById('submit').addEventListener('click', function() {
geocodeAddress(geocoder, map);
});
}
function geocodeAddress(geocoder, map) {
geocoder.geocode({
componentRestrictions: {
country: 'AU',
postalCode: '2000'
}
}, function(results, status) {
if (status === 'OK') {
map.setCenter(results[0].geometry.location);
