Let’s get started.

Getting Started with Google Map API Key

Before using the Places library in the Maps JavaScript API, first you need to make sure that the Places API is enabled in the Google Cloud Console, in the same project you set up for the Maps JavaScript API.

To view your list of enabled APIs:

  • Go to the Google Cloud Console.
  • Click the Select a project button, then select the same project you set up for the Maps JavaScript API and click Open.
  • From the list of APIs on the Dashboard, look for Places API.
  • If you see the API in the list, you’re all set. If the API is not listed, enable it:
    1. At the top of the page, select ENABLE API to display the Library tab. Alternatively, from the left side menu, select Library.
    2. Search for Places API, then select it from the results list.
    3. Select ENABLE. When the process finishes, Places API appears in the list of APIs on the Dashboard.

                        <div class="form-group">
                            <label for="autocomplete"> Location </label>
                            <input type="text" name="autocomplete" id="autocomplete" class="form-control" placeholder="Select Location">
                        </div>

                        <div class="form-group" id="lat_area">
                            <label for="latitude"> Latitude </label>
                            <input type="text" name="latitude" id="latitude" class="form-control">
                        </div>

                        <div class="form-group" id="long_area">
                            <label for="latitude"> Longitude </label>
                            <input type="text" name="longitude" id="longitude" class="form-control">
                        </div>
                    </div>

                </div>
            </div>
        </div>
    </div>
    <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
    <script src="https://maps.google.com/maps/api/js?key=AIzaxxxXSQRl-XLDybXXX9cBcNtoZ1HXXxXxxXX&libraries=places&callback=initAutocomplete" type="text/javascript"></script>
    <script src="./map.js"></script>
</body>

</html>

When page loads, initAutocomplete() will be called.

<script src="https://maps.google.com/maps/api/js?key=AIzaxxxXSQRl-XLDybXXX9cBcNtoZ1HXXxXxxXX&libraries=places&callback=initAutocomplete" type="text/javascript"></script>

Open map.js file and write this code into it.

$(document).ready(function() {
    $("#lat_area").addClass("d-none");
    $("#long_area").addClass("d-none");
});

google.maps.event.addDomListener(window, 'load', initialize);

function initialize() {

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

    autocomplete.addListener('place_changed', function() {
        var place = autocomplete.getPlace();
        $('#latitude').val(place.geometry['location'].lat());
        $('#longitude').val(place.geometry['location'].lng());

        // --------- show lat and long ---------------
        $("#lat_area").removeClass("d-none");
        $("#long_area").removeClass("d-none");
    });
}

Application Testing

Now,

Open project into browser and type this URL into it.

URL: http://localhost/map-locations/index.html

Search for any address. It will give your all google places search locations.

Whenever you search and click on any location, you will get latitude and longitude of selected location.

In case, if you don’t have your valid Map API then you will get map errors.
