javascript - 如何在 Google map API 中设置数据层特征标签的样式？

Question

我有这个有效的 js 代码:

var p;
p = new google.maps.Data();
p.loadGeoJson('http://mysource.example.com');
p.setStyle( function(feature){
    var icon = feature.getProperty('icon');
    var title = feature.getProperty('title');
    return  { 
        icon: icon,
        label: title
    }
});
p.setMap(map);

代码生成此输出:

p.setStyle(function(feature) {
  var icon = feature.getProperty('icon');
  var title = feature.getProperty('title');
  return {
    icon: {
      url: icon,
      labelOrigin: new google.maps.Point(15, -10)
    },
    label: {
      color: "blue",
      fontFamily: "Courier",
