javascript - 谷歌地图 API : Adding letters to my markers on my google map

Question

我正在尝试向我的标记添加一个字母，然后有多个带有字母的标记(准确地说是 14 个)。到目前为止，我没有成功地做到这一点。我是代码和 google API 的新手。

你能告诉我需要添加什么代码以及在哪里添加吗？

下面是我的代码:

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=....
  type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
function load() {
  if (GBrowserIsCompatible()) {

    var map = new GMap2(document.getElementById("map"));
    map.addControl(new GMapTypeControl());
    map.addControl(new GLargeMapControl());
    map.addControl(new GOverviewMapControl());
    map.addControl(new GScaleControl());


    var bounds = map.getBounds();
    var southWest = bounds.getSouthWest();
    var northEast = bounds.getNorthEast();
    var lngSpan = northEast.lng() - southWest.lng();
    var latSpan = northEast.lat() - southWest.lat();
    for (var i = 0; i < 10; i++) {
    var point = new GLatLng(southWest.lat() + latSpan * Math.random(),
        southWest.lng() + lngSpan * Math.random());
    map.addOverlay(new GMarker(point));

    var point = new GLatLng(lat,ling);
    map.setCenter(point, 10);
    var marker = new GMarker(point);
    map.addOverlay(marker);

   GEvent.addListener(map, "moveend", function() {
   var center = map.getCenter();
   document.getElementById("message").innerHTML = center.toString();
   });



    map.setCenter(new GLatLng(lat,ling), 7);

  }
}
//]]>
</script>
<style type="text/css">

这是添加字母标记的代码。对所有标记运行循环，索引是每个标记位置

let letter = String.fromCharCode("A".charCodeAt(0) + index),
marker = new google.maps.Marker({
    map: this.map,
    position: latLongObj,
    icon: "http://maps.google.com/mapfiles/marker" + letter + ".png",
    animation: google.maps.Animation.DROP
});

Here is the list of map marker icons
