在谷歌地圖api中刪除運輸路線的車輛信息

Question

我已經使用谷歌地圖API的Transit層進行了應用程序。我的應用程序頁面如下所示： 當我創建路線時，我得到了兩件我想要的東西從地圖擦除。 1）我使用suppressMarkers成功移除的標記A B。

2）圖片中的白色信息窗口向我提供有關使用的路線種類和所用服務的信息，可在this鏈接中看到。 就像我要刪除的孟買CST-Kalyan窗口。

我無法找到如何刪除它們。請指導。

如果您像本示例一樣呈現自己的方向，則不會顯示這些方向。

function calcRoute() { 
    polyline.setMap(null); 
    var start = document.getElementById("search1").value; 
    var end = document.getElementById("search2").value; 
    var request = { 
     origin: start, 
     destination: end, 
     travelMode: getSelectedTravelMode() 
    }; 

    polyline = new google.maps.Polyline({ 
     path: [], 
     strokeColor: '#FF0000', 
     strokeWeight: 3 
    }); 

    directionsService.route(request, function(response, status) { 
     if (status == google.maps.DirectionsStatus.OK) { 
     var bounds = new google.maps.LatLngBounds(); 
     var route = response.routes[0]; 
     var summaryPanel = document.getElementById("directions_panel"); 
     var detailsPanel = document.getElementById("direction_details"); 
     startLocation = new Object(); 
     endLocation = new Object(); 

     summaryPanel.innerHTML = ""; 
     detailsPanel.innerHTML = '<ul>'; 

     // For each route, display summary information. 
     for (var i = 0; i < route.legs.length; i++) { 
      var routeSegment = i + 1; 
      summaryPanel.innerHTML += "<b>Route Segment: " + routeSegment + "</b><br />"; 
      summaryPanel.innerHTML += route.legs[i].start_address + " to "; 
      summaryPanel.innerHTML += route.legs[i].end_address + "<br />"; 
      summaryPanel.innerHTML += route.legs[i].distance.text + "<br /><br />"; 
     } 
    var path = response.routes[0].overview_path; 
    var legs = response.routes[0].legs; 
     for (i=0;i<legs.length;i++) { 
      if (i == 0) { 
      startLocation.latlng = legs[i].start_location; 
      startLocation.address = legs[i].start_address; 
      createMarker(legs[i].start_location,"start",legs[i].start_address,"green"); 
      } 
      endLocation.latlng = legs[i].end_location; 
      endLocation.address = legs[i].end_address; 
      var steps = legs[i].steps; 
      for (j=0;j<steps.length;j++) { 
      var nextSegment = steps[j].path; 
      detailsPanel.innerHTML += "<li>"+steps[j].instructions; 
      var dist_dur = ""; 
      if (steps[j].distance && steps[j].distance.text) dist_dur += "&nbsp;"+steps[j].distance.text; 
      if (steps[j].duration && steps[j].duration.text) dist_dur += "&nbsp;"+steps[j].duration.text; 
      if (dist_dur != "") { 
       detailsPanel.innerHTML += "("+dist_dur+")<br /></li>"; 
      } else { 
       detailsPanel.innerHTML += "</li>"; 

      } 
      for (k=0;k<nextSegment.length;k++) { 
       polyline.getPath().push(nextSegment[k]); 
       bounds.extend(nextSegment[k]); 
      } 
      } 
     } 

     detailsPanel.innerHTML += "</ul>" 
     polyline.setMap(map); 
     map.fitBounds(bounds); 
     createMarker(endLocation.latlng,"end",endLocation.address,"red"); 
     // == create the initial sidebar == 
     makeSidebar(); 

     } 
    }); 
}
