</head>
<body>

<div>
     <h3> Enter an adress and press the button</h3>

    <div>
        <p>Latitude:
            <input type="text" id="latitude" readonly />
        </p>

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&key=PUT_GOOGLE_API_KEY_HERE&libraries=places"></script>

Like following:

<!-- Add the this google map apis to webpage -->
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&key=PUT_GOOGLE_API_KEY&libraries=places"></script>

<script>
google.maps.event.addDomListener(window, 'load', initialize);
function initialize() {
var input = document.getElementById('address');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.addListener('place_changed', function () {
var place = autocomplete.getPlace();
// place variable will have all the information you are looking for.

  document.getElementById("latitude").value = place.geometry['location'].lat();
  document.getElementById("longitude").value = place.geometry['location'].lng();
