Por favor, alguém pode ajudar - me a alterar o meu código de modo a permitir que a API do Google Maps solicite um Endereço em seu lugar porque eu quero ler o endereço do usuário diretamente do banco de dados mySQL.

Veja este exemplo, inicializa o mapa para "San Diego, CA".
Usa o Google Maps Javascript API v3 Geocoder para traduzir o endereço em coordenadas que podem ser apresentadas no mapa.

Excerto do código de trabalho:
var geocoder;
var map;
var address = "San Diego, CA";
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
if (geocoder) {
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (status != google.maps.GeocoderStatus.ZERO_RESULTS) {
map.setCenter(results[0].geometry.location);
var infowindow = new google.maps.InfoWindow({
content: '<b>' + address + '</b>',
size: new google.maps.Size(150, 50)
});
var marker = new google.maps.Marker({
position: results[0].geometry.location,
map: map,
title: address
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
} else {
alert("No results found");
}
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
}
google.maps.event.addDomListener(window, 'load', initialize);
html,
body,
#map_canvas {
height: 100%;
width: 100%;
}
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<div id="map_canvas" ></div>
Aqui está o meu código para gerar o mapa a partir da localização
Código HTML
<div class="col-md-2">
<address> <?php echo $doctorInfo[0]->serachLocation;?> // set address for which you need to generate map</address>
</div>
Código Javascript
<script>
$(document).ready(function(){
$("address").each(function(){
var embed ="<iframe width='425' height='350' frameborder='0'
scrolling='no' marginheight='0' marginwidth='0'
src='https://maps.google.com/maps?&q="+
encodeURIComponent( $(this).text() ) +"&output=embed'>
</iframe>";
$(this).html(embed);
});
});
</script>
Geocodificação é o processo de conversão de endereços (como "1600 Amphitheatre Parkway, Mountain View, CA") em coordenadas geográficas (como latitude 37.423021 e longitude -122.083739), que você pode usar para colocar os marcadores ou posição do mapa.
Isto Seria o que você está procurando: Contém exemplos de code
https://developers.google.com/maps/documentation/javascript/geocoding#GeocodingRequests
Podes analisar a geolocalização através dos endereços. Crie um Array com jquery como este:
var addressesArray = [
'Address Str.No, Postal Area/city',
//follow this structure
]
//loop all the addresses and call a marker for each one
for (var x = 0; x < addressesArray.length; x++) {
$.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addressesArray[x]+'&sensor=false', null, function (data) {
var p = data.results[0].geometry.location
var latlng = new google.maps.LatLng(p.lat, p.lng);
var aMarker= new google.maps.Marker({
position: latlng, //it will place marker based on the addresses, which they will be translated as geolocations.
map: map
});
}
Por favor, note também que o Google limita os seus resultados se não tiver uma conta de negócios com eles, e você terá um erro se usar demasiados endereços.
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map'), mapOptions);
}
function codeAddress() {
var address = document.getElementById('address').value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == 'OK') {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
