在stackoverflow的某个地方，我发现这个（我稍微修改了一下）可以从Google maps中呈现基本的驾驶说明：

<!DOCTYPE html>
<html> 
<head> 
   <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
   <title>Google Maps API v3 Directions Example</title> 
   <script type="text/javascript" 
           src="http://maps.google.com/maps/api/js?sensor=false&language=de"></script>
</head> 
<body style="font-family: Arial; font-size: 12px;"> 
   <div style="width: 600px;">
     <div id="map" style="width: 500px; height: 400px; float: left;"></div> 
     <div id="panel" style="width: 500px; float: left;"></div> 
   </div>

   <script type="text/javascript"> 

     var directionsService = new google.maps.DirectionsService();
     var directionsDisplay = new google.maps.DirectionsRenderer();

     var map = new google.maps.Map(document.getElementById('map'), {
       zoom:7,
       mapTypeId: google.maps.MapTypeId.ROADMAP
     });

     directionsDisplay.setMap(map);
     directionsDisplay.setPanel(document.getElementById('panel'));

     var request = {
       origin: 'An der Alster 1, Hamburg', 
       destination: 'Albada 1, Cala Llombards, Mallorca',
       travelMode: google.maps.DirectionsTravelMode.DRIVING
     };

     directionsService.route(request, function(response, status) {
       if (status == google.maps.DirectionsStatus.OK) {
         directionsDisplay.setDirections(response);
       }
     });
   </script> 
</body> 
</html>

请参阅下面的标记和代码，它从文本框中获取输入，并从下拉框中获取旅行模式-

HTML-

Start:<input type="text" id="start">
End:<input type="text" id="end">
<div>
<strong>Mode of Travel: </strong>
<select id="mode" onchange="calcRoute();">
  <option value="DRIVING">Driving</option>
  <option value="WALKING">Walking</option>
  <option value="BICYCLING">Bicycling</option>
  <option value="TRANSIT">Transit</option>
</select>
</div>

function calcRoute() {
  var selectedMode = document.getElementById("mode").value;
  var start = document.getElementById("start").value;
  var end = document.getElementById("end").value;
  var request = {
    origin:start,
    destination:end,
    travelMode: google.maps.TravelMode[selectedMode]
  };
  directionsService.route(request, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(result);
    }
  });
}

谢谢其他人，futre me等：完整复制和粘贴HTML见上文。正因为我觉得这很有趣：浏览1006次，我赢得了“热门问题”徽章——零票；）
