how can I upload an image in my project folder and in my database, and how can I save the latitude and longitude google maps fields in my database

I have used this script

<script type="text/javascript">

var geocoder; var map;

function initialiserCarte() { geocoder = new google.maps.Geocoder();

var latlng = new google.maps.LatLng(36.800519, 10.179326); var mapOptions = { zoom : 14, center : latlng, mapTypeId : google.maps.MapTypeId.ROADMAP } var options = {

types: ['(cities)'],

componentRestrictions: {country: 'tn'}

};

var input = document.getElementById('address');

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

map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); }

function TrouverAdresse() {

var adresse = document.getElementById('address').value; geocoder.geocode( { 'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location);

  var strposition = results[0].geometry.location+"";
  strposition=strposition.replace('(', '');
  strposition=strposition.replace(')', '');
  document.getElementById('text_latlng').innerHTML= strposition;

  var marker = new google.maps.Marker({
      map: map,
      position: results[0].geometry.location
  });
} else {
  alert('Adresse introuvable: ' + status);
}

}); }

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

this code works in a simple html page but no in a laravel page, I puts this script in the layout and this is my vue :

                                        <div class="form-group{{ $errors->has('address') ? ' has-error' : '' }}" style="color:red;" >
                                            <label for="address" class="field prepend-icon"  >
                                                <input type="texte" id="address" name="address" value="{{ old('address') }}" style="width: 75%; float: left;"  class="gui-input" placeholder="Donner l'adresse de votre établissement...">

                                                <label for="address" class="field-icon">
                                                    <i class="fa fa-home"></i>
                                                </label>
                                            </label><br clear="all">
                                        </div>
                                                <input type="button"  value="Localiser sur Google Map" onclick="TrouverAdresse();"/>

                                       <!-- <span id="text_latlng"></span>-->
                                   


                                            <span id="text_latlng"></span>

but the function TrouverAdresse(); doesn't work, can you help me please ? and thanks
