Does your application include an address form, such as the Billing and Shipping address for your online store, a credit card billing address, or a taxi booking form? Autocomplete can help users supply the details.
This feature i based on Places library in the Google Maps JavaScript API. You can use autocomplete to give your applications the type-ahead-search behavior of the Google Maps search field. When a user starts typing an address, autocomplete will fill in the rest.

var defaultBounds = new google.maps.LatLngBounds( new google.maps.LatLng(-33.8902, 151.1759), new google.maps.LatLng(-33.8474, 151.2631)); var input = document.getElementById('searchTextField'); var options = { bounds: defaultBounds, types: ['establishment'] }; autocomplete = new google.maps.places.Autocomplete(input, options); |
By default, autocomplete will give you the full address as a single line of text. For an address form, it is useful to get the address in structured format.
Below code will autocomplete fill your address form.
