javascript google maps API - 更改标记的标题

Question

我正在尝试在谷歌地图标记图标上填充小注释。标题似乎没有这样做。我阅读了文档，但找不到任何东西。

https://developers.google.com/maps/documentation/javascript/examples/marker-labels

var marker = new google.maps.Marker({
                    position: new google.maps.LatLng(locations[i]["lat"], locations[i]["lng"]),
                    map: map,
                    title: "a title here"


                  });

现在注释是空白的，即使注释的标题已设置。我从来没有弄清楚标题的实际用途，因为标签是图标内的字符，而标题对注释没有影响。

标记的属性是什么，您可以使用它在注释中填充文本？

编辑： 谢谢 Samuel Toh。

这是我最终使用的工作代码：

var locations;// use this as the array which holds the data 
for (i = 0; i < locations.length; i++) {  
    about the locations you are adding to the map
    var marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[i]["lat"], locations[i]["lng"]),
        map: map,
        title: activities[i]["city"]

     });


     //extend the bounds to include each markers position
     bounds.extend(marker.position);

     google.maps.event.addListener(marker, "click", (function(marker, i) {
          return function() {
              infowindow.setContent(locations[i]["city"]);
              infowindow.open(map, marker);
          }
      })(marker, i));
}

您需要一个infoWindow 对象来显示标题文本。

见：https://developers.google.com/maps/documentation/javascript/examples/infowindow-simple

var infowindow = new google.maps.InfoWindow({
    content: "<span>any html goes here</span>" });

var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    title: 'Uluru (Ayers Rock)' });

google.maps.event.addListener(marker, 'click', function() {   infowindow.open(map,marker); });
