谁能告诉我如何使折线连续闪烁，不使用坐标。我已经在没有坐标的谷歌地图中绘制了一条折线，但我不能像使用坐标的闪烁那样闪烁。

闪烁的折线与坐标

没有坐标的折线（如何像上面一样闪烁这个）

我的代码如下

$(function(){
 var map    = new google.maps.Map(document.getElementById("map"), {
                  center: new google.maps.LatLng(11.275387916698238, 75.8015380957031),
                  zoom: 12
               }),
     routes = [{origin:'p t usha road, kozhikode', 
               destination:'cooperative hospital, eranjipalam, kozhikode'
               }, 
               {origin:'IIM, Kozhikode',
               destination:'VELLIMADUKUNNU, KOZHIKODE'
               }
              ],
     rendererOptions = {
                preserveViewport: true,
                map:map,
                polylineOptions:{strokeColor:'#FF3300',

                suppressMarkers:true,
                routeIndex:0

     directionsService = new google.maps.DirectionsService();
    var i=0;
var infowindow = new google.maps.InfoWindow();
      $.each(routes,

        var request = {

            directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions);
            directionsService.route(request, function(result, status) {

              if (status == google.maps.DirectionsStatus.OK) {

var lat = result.routes[0].legs[0].start_location.lat();

DirectionsRenderer 创建的折线无法通过 API 访问。

你可以做什么：切换渲染器的设置（例如supressPolylines）并重绘结果：

setInterval(function () {

    directionsDisplay.set('suppressPolylines', 
                          !directionsDisplay.get('suppressPolylines'));
    directionsDisplay.setDirections(result);

}, 2000);
