I'd like to do a search on that, from the source address, I get routes to 5 other points. Here is the code I already use:
<script src="http://maps.google.com/maps/api/js?sensor=false"></script><scripttype="text/javascript">
function CalculaDistancia() {
$('#litResultado').html('Aguarde...');
//Instanciar o DistanceMatrixService
var service = new google.maps.DistanceMatrixService();
//executar o DistanceMatrixService
service.getDistanceMatrix(
{
//Origem
origins: [$("#txtOrigem").val()],
//Destino
destinations: [$("#txtDestino").val()],
//Modo (DRIVING | WALKING | BICYCLING)
travelMode: google.maps.TravelMode.DRIVING,
//Sistema de medida (METRIC | IMPERIAL)
unitSystem: google.maps.UnitSystem.METRIC
//Vai chamar o callback
}, callback);
}
//Tratar o retorno do DistanceMatrixService
function callback(response, status) {
//Verificar o Status
if (status != google.maps.DistanceMatrixStatus.OK)
//Se o status não for "OK"
$('#litResultado').html(status);
else {
//Se o status for OK
//Endereço de origem = response.originAddresses
//Endereço de destino = response.destinationAddresses
//Distância = response.rows[0].elements[0].distance.text
//Duração = response.rows[0].elements[0].duration.text
$('#litResultado').html("<strong>Origem</strong>: " + response.originAddresses +
"<br /><strong>Destino:</strong> " + response.destinationAddresses +
"<br /><strong>Distância</strong>: " + response.rows[0].elements[0].distance.text +
" <br /><strong>Duração</strong>: " + response.rows[0].elements[0].duration.text
);
//Atualizar o mapa
$("#map").attr("src", "https://maps.google.com/maps?saddr=" + response.originAddresses + "&daddr=" + response.destinationAddresses + "&output=embed");
}
}
