我想将方向图的默认显示更改为：

  • 显示终点的缩放图像，路线以蓝色表示
  • 显示缩放气球和端点标记 (http://www.birdwingfx.com/jQuery_gps/demo_gps/gps_demo.html)

我制作了这个仅显示整个路线的基本脚本：

<!DOCTYPE html>
<html>
  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <style type="text/css">
      html { height: 100% }
      body { height: 100%; margin: 0; padding: 0 }
      #map_canvas { height: 100% }
    </style>
    <script type="text/javascript"
      src="http://maps.googleapis.com/maps/api/js?key=AIzaSyBSHoB4rbbeXHf_KfV-pONQvTiSLIJH_G8&sensor=false">
    </script>
    <script type="text/javascript"> 
        var directionsDisplay;
        var directionsService = new google.maps.DirectionsService();
        var map;
        var bilzen = new google.maps.LatLng(50.87228390728491, 5.512539388885443);

        function initialize() {
            directionsDisplay = new google.maps.DirectionsRenderer();
            var Bilzen = new google.maps.LatLng(50.87228390728491, 5.512539388885443);
            var myOptions = {
                zoom:11,
            mapTypeId: google.maps.MapTypeId.ROADMAP,
            center: bilzen
        }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    directionsDisplay.setMap(map);
    }

  function calcRoute() {
    var start = document.getElementById("start").value;
    var end = document.getElementById("end").value;
    var request = {
        origin:start, 
        destination:end,
        travelMode: google.maps.DirectionsTravelMode.DRIVING,
        unitSystem: google.maps.DirectionsUnitSystem.metric
};
directionsService.route(request, function(response, status) {
  if (status == google.maps.DirectionsStatus.OK) {
    directionsDisplay.setDirections(response);
  }
});
  }
    </script>
  </head>
  <body onload="initialize()">
<form action="#" onsubmit="calcRoute(); return false;" >
    <input name="start" id="start" value="start" type="text">
    <input name="end" id="end" value="end" type="text">
    <input name="Submit" type="submit">
    </form>

    <div id="map_canvas" style="width:100%; height:100%"></div>
  </body>
</html>

我在这里有一些技巧：http: //jsfiddle.net/mR2LV/6/单击提交，然后单击红色汽车图标以打开信息窗口。

此脚本假定路径仅为 A 点到 B 点（简单）。它使用两个独立的地图，一个进入信息窗口“气泡”和整体地图。这个想法是保留相同信息的两份副本，并将一份用于“缩放”。路线在变量中path。

minimap = new google.maps.Map(document.getElementById("minimap"), miniOptions);

if(document.getElementById("minimap")) {
    document.getElementById("minimap").style.display= "block";
    infomap.setContent(document.getElementById("minimap"));
}

var path = response.routes[0].overview_path;


google.maps.event.addListener(endMarker, 'click', function(event) {
    infomap.open(map, this);
    google.maps.event.trigger(minimap, 'resize'); 
    minimap.setCenter(path[path.length-1]);
});


<div id="map_canvas" style="width:100%; height:100%"></div>
<div id="minimap" style="width: 220px; height:200px; display: none"></div>
