I have a geolocation code, but Chrome won’t give me permission to execute it

Question

I would like to know, if I have to give some kind of permission, for the code to work in Chrome, because in mozila it can give me the location. Follow the code below`

function writeAddressName(latLng) {
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({
    "location": latLng

    },
    function(results, status) {
      if (status == google.maps.GeocoderStatus.OK)
        document.getElementById("address").innerHTML = results[0].formatted_address;
      else
        document.getElementById("error").innerHTML += "Unable to retrieve your address" + "<br />";
    });
  }



  function geolocationSuccess(position) {
    var userLatLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
    // Escreva o endereço da localização
    writeAddressName(userLatLng);





    // Coloque o marcador na posição do usuario
      new google.maps.Marker({
      map: map,
      icon:'img/aqui',
      position: userLatLng

    });


    // Desenhe um círculo em torno da posição do usuário para ter uma idéia da precisão de localização atual
    var circle = new google.maps.Circle({
      center: userLatLng,
      radius: 500,
      map: map,
      fillColor: '#0000FF',
      fillOpacity: 0.3,
      strokeColor: '#0000FF',
      strokeOpacity: 1.0,


    });
    map.fitBounds(circle.getBounds());
  }

  function geolocationError(positionError) {
    document.getElementById("error").innerHTML += "Error: " + positionError.message + "<br />";
  }

  function geolocateUser() {
    // Verifica se o navegador suportar a Geolocation API
    if (navigator.geolocation)
    {
      var positionOptions = {
        enableHighAccuracy: true,
        timeout: 10 * 1000 // 10 seconds

      };
      navigator.geolocation.getCurrentPosition(geolocationSuccess, geolocationError, positionOptions);
    }
    else
      document.getElementById("error").innerHTML += "Your browser doesn't support the Geolocation API";
  }

  window.onload = geolocateUser;

Turning Pedro Augusto’s comment into a response. The Chromium people (the project Chrome is based on) no longer accept certain features to work over HTTP. You will only be able to use on top of HTTPS for security reasons.

We want to start Applying the Concepts in https://w3c.github.io/webappsec-secure-contexts/ to Features that have already shipped and which do not Meet the (new, not present at the time) Quirements. In particular, this approximately requires that Powerful Features only be accessible on "Secure Origins" (such as HTTPS)

Free translation:

We want to start applying the concepts in https://w3c.github.io/webappsec-secure-contexts/ functionalities that have already been released and that do not fit the new requirements (that were not present when the functionalities were released). In particular, this means that powerful [sic] features will only be accessible from secure sources (such as HTTPS).

In other words: you’ll need an SSL certificate on your server to continue using Chrome geolocation the way you’re doing.
