How To Move Marker To Autocomplete Api Predicted Address?

I'm trying to do this by these lines: var marker = new google.maps.Marker({ position: geolocation, animation: google.maps.Animation.BOUNCE }); marker.setPositi

Solution 1:

To place a marker on the position returned by the Autocomplete result, add it in the fillInAddress function (which is runs on the selection of a "place" and gets the result by calling autocomplete.getPlace();)

functionfillInAddress() {
  // Get the place details from the autocomplete object.var place = autocomplete.getPlace();
  if (marker && marker.setMap) 
    marker.setMap(null);
  marker = new google.maps.Marker({
    position: place.geometry.location,
    animation: google.maps.Animation.BOUNCE,
    map: map
  });
  marker.setPosition(place.geometry.location);
  map.setCenter(place.geometry.location);
  if (place.geometry.viewport) 
    map.fitBounds(place.geometry.viewport);

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details// and fill the corresponding field on the form.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]];
      console.log(val);
      document.getElementById(addressType).value = val;
    }
  }
}

The above code assumes that marker and map are in the global (or at least an enclosing) scope.

code snippet:

var placeSearch, autocomplete;
var componentForm = {
  street_number: 'short_name',
  route: 'long_name',
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  country: 'long_name',
  postal_code: 'short_name'
};
var map;
var marker;

functioninitAutocomplete() {
  var mapCanvas = document.getElementById("map");
  var myCenter = new google.maps.LatLng(62, -110.0);
  var mapOptions = {
    center: myCenter,
    zoom: 3
  };
  map = new google.maps.Map(mapCanvas, mapOptions);
  marker = new google.maps.Marker({
    position: myCenter,
    animation: google.maps.Animation.BOUNCE
  });
  google.maps.event.addListener(marker, 'click', function() {
    map.setZoom(2 * mapOptions.zoom);
    map.setCenter(marker.getPosition());
  });
  marker.setMap(map);

  google.maps.event.addListener(map, "click", function(e) {

    //lat and lng is available in e objectplaceMarker(map, e.latLng);
    // var latLng = e.latLng;// console.log("lat" + latLng.lat() + "long" + latLng.lng());
  });

  functionplaceMarker(map, location) {

    marker.setPosition(location);

    var infowindow = new google.maps.InfoWindow({
      content: 'Latitude: ' + location.lat() + '<br>Longitude: ' + location.lng()
    });
    infowindow.open(map, marker);
  }

  // Create the autocomplete object, restricting the search to geographical// location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement} */
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });

  // When the user selects an address from the dropdown, populate the address// fields in the form.
  autocomplete.addListener('place_changed', fillInAddress);
}

functionfillInAddress() {
  // Get the place details from the autocomplete object.var place = autocomplete.getPlace();
  if (marker && marker.setMap)
    marker.setMap(null);
  marker = new google.maps.Marker({
    position: place.geometry.location,
    animation: google.maps.Animation.BOUNCE,
    map: map
  });
  marker.setPosition(place.geometry.location);
  map.setCenter(place.geometry.location);
  if (place.geometry.viewport)
    map.fitBounds(place.geometry.viewport);

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details// and fill the corresponding field on the form.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]];
      console.log(val);
      document.getElementById(addressType).value = val;
    }
  }
}

// Bias the autocomplete object to the user's geographical location,// as supplied by the browser's 'navigator.geolocation' object.functiongeolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      console.log(geolocation.lat);
    });
  }
}
google.maps.event.addDomListener(window, "load", initAutocomplete);
