onMarkerTap(e){

let that = this;

let markers = that.position;

console.log(e.markerId)

for (let i = 0; i < markers.length; i++) {

  if(markers[i].id != e.markerId){

markers[i].callout.display = "BYCLICK"

}else{

markers[i].callout.display = "ALWAYS"

}

}

this.drawMap()

}

drawMap(){

let that = this;

let markers = that.position;

that._mapContext.addMarkers({

markers: markers,

clear: true,

fail:function(err){

console.log(err)

}

})

},

这是我为了解决，点聚合缩放地图之后，会有部分标记点击不显示气泡，并且callout不是点击一个显示一个的问题，才想出来的，结果重新绘制标记点会发生闪烁
