Get Latitude and Longitude Based on Location Name with Google Autocomplete API

Coding & Programming

If you are searching for a way to create a textbox in your webpage which can get latitude and longitude based on an entered location name, then you are at the right place. The code i will be providing here has Google Autocomplete API which means that while users are entering the letters of the location in the textbox, suggestions will be provided to help ease the search.

I know how important this is to some developers which made me provide two separate codes that will give same result but with separate information. In case you require more assistant from me, you can always use the comment box below and i will be very glad to assist you.

So to create a textbox in your webpage which can get the latitude and longitude of any keyed in location name, go through the guide below;

  • Copy and paste the code below in between the <head> and </head> of your webpage code.
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
        <script type="text/javascript">
        function initialize() {
        var address = (document.getElementById('my-address'));
        var autocomplete = new google.maps.places.Autocomplete(address);
        google.maps.event.addListener(autocomplete, 'place_changed', function() {
            var place = autocomplete.getPlace();
            if (!place.geometry) {

        var address = '';
        if (place.address_components) {
            address = [
                (place.address_components[0] && place.address_components[0].short_name || ''),
                (place.address_components[1] && place.address_components[1].short_name || ''),
                (place.address_components[2] && place.address_components[2].short_name || '')
                ].join(' ');
function codeAddress() {
    geocoder = new google.maps.Geocoder();
    var address = document.getElementById("my-address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {

      alert("Latitude: "+results[0].geometry.location.lat());
      alert("Longitude: "+results[0].geometry.location.lng());

      else {
        alert("Geocode was not successful for the following reason: " + status);
google.maps.event.addDomListener(window, 'load', initialize);


As you can see in the code above, there is an autocomplete function, it fetches the address from the input and gets auto completed by the API while typing.

  • Next, in between the <body> and </body> tag copy and paste the code below.
<input type="text" id="my-address">
        <button id="getCords" onClick="codeAddress();">Get Lat & Long</button>

The code above displays the text box where users are required to enter the location name they wish to get its latitude and longitude. Once the users have entered location and probably gotten the address, all they need to do hit the Get Lat & Long button and they will get the results as requested.

Note: The above uses the latest API and it loads the ‘places’ library (when calling the API uses the ‘libraries’ parameter).

The second code i will be providing as i mentioned gives a result that is somewhat different from that above. The result will look like as shown in the image below. This will also fetch the address from the input and auto complete by the API while typing.

So to add this code instead of the one provided above, go through the guide below;

  • Copy and paste the code below in between <head> and </head> of your webpage code.
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>

<link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500">
  • Next copy the code below and paste between <body> and </body> of your webpage code.
<textarea placeholder="Enter Area name to populate Latitude and Longitude" name="address" onFocus="initializeAutocomplete()" id="locality" ></textarea><br>

<input type="text" name="city" id="city" placeholder="City" value="" ><br>
<input type="text" name="latitude" id="latitude" placeholder="Latitude" value="" ><br>
<input type="text" name="longitude" id="longitude" placeholder="Longitude" value="" ><br>
<input type="text" name="place_id" id="location_id" placeholder="Location Ids" value="" ><br>

<script type="text/javascript">
  function initializeAutocomplete(){
    var input = document.getElementById('locality');
    // var options = {
    //   types: ['(regions)'],
    //   componentRestrictions: {country: "IN"}
    // };
    var options = {}

    var autocomplete = new google.maps.places.Autocomplete(input, options);

    google.maps.event.addListener(autocomplete, 'place_changed', function() {
      var place = autocomplete.getPlace();
      var lat = place.geometry.location.lat();
      var lng = place.geometry.location.lng();
      var placeId = place.place_id;
      // to set city name, using the locality param
      var componentForm = {
        locality: 'short_name',
      for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType]) {
          var val = place.address_components[i][componentForm[addressType]];
          document.getElementById("city").value = val;
      document.getElementById("latitude").value = lat;
      document.getElementById("longitude").value = lng;
      document.getElementById("location_id").value = placeId;

Finally, copy the code below and paste just after the </html> closing tag

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="//maps.googleapis.com/maps/api/js?libraries=places&key=API KEY"></script>

<script src="https://fonts.googleapis.com/css?family=Roboto:300,400,500></script>

Please ensure you replace API KEY as highlighted in RED in the code above with your Google API key.

That’s it! Make use any of the guide and you should have a text box displayed in your webpage where users can simply enter a location and get the latitude and longitude of that location. Remember that each of the codes already have a Google Autocomplete API which makes searching easy and faster.
