Question

我已经制作了一个应用程序，在google-maps中打印多个折线，每一行都以标记A作为起点，最后会有一个标记B，如 JSFIDDLE 。问题是，当我打印10-15行时，标记丢失，特别是标记B。

任何人都可以告诉我一些解决方案吗

查看我的 JSFIDDLE

我的代码如下所示

$(function(){

 var map    = new google.maps.Map(document.getElementById("map"), {
                  center: new google.maps.LatLng(11.275387916698238, 75.8015380957031),
                  zoom: 12
               }),



     routes = [

缺少的标记位于其他标记之下（我在这个fiddle中使它们可拖动。另请注意，您正在进入配额/速率限制（获得OVER_QUERY_LIMIT的状态响应）。

var marker1 = new google.maps.Marker({
  position: new google.maps.LatLng(lat, lon),
  draggable: true,
  icon:'https://mts.googleapis.com/vt/icon/name=icons/spotlight/spotlight-waypoint-b.png&text=B&psize=16&font=fonts/Roboto-Regular.ttf&color=ff333333&ax=44&ay=48&scale=1',
  map: map
});

var marker2 = new google.maps.Marker({
  position: new google.maps.LatLng(lat1, lon1),
  draggable: true,
  icon:'https://mts.googleapis.com/vt/icon/name=icons/spotlight/spotlight-waypoint-a.png&text=A&psize=16&font=fonts/Roboto-Regular.ttf&color=ff333333&ax=44&ay=48&scale=1',
  map: map
});

这是一个有用的更改（因此您可以看到错误发生的时间）：

  directionsDisplay.setDirections(result);
} else { 
  // output error status messages
  document.getElementById('info').innerHTML += "Directions Request["+i+"] Failed: "+status + "<br>"; 
}

没有在谷歌地图中正确获得标记A和B.
