<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>

var markers = [

    description: 'The Big Apple'
  },

    position: { lat: 34.052235, lng: -118.243683 },
    title: 'Los Angeles',
    description: 'The City of Angels'
  },
  // 添加更多标记对象...
];

<div id="map"></div>
