vue3 数据可视化大屏 开发中，需要渲染高德地图，地图中覆盖物图标不能满足我们的需要，需要使用自定义html来实现我们想要的效果。

创建一个marker,并通过setContent来将我们的html代码插入到marker中，实现marker自定义html。

关键代码

addMarker(x, y, info) {
  var marker = new AMap.Marker({
    position: [x, y],
    offset: new AMap.Pixel(-50, -30),
    content: ``,
    extData: info
  });
  var markerContent = document.createElement("div");
  marker.setPosition([x, y]);
  markerContent.innerHTML = `<div class="bgInfo"><span>${info.title}</span></div>`
  marker.setContent(markerContent);
  marker.setMap(this.map);
},
