js更新属性：
<HMap v-if="mapshow" ref="hmap" style="width: 100%; height: 400rpx;" showcorver:"true" :markers="markcovers" :location="location"></HMap>
// 无论怎么改变covers或者下面的lat和long数据，都不会触发updateAttributes
computed: {
markcovers() {
console.log("computed markcovers")
return this.covers
},
location() {
console.log("computed location")
return {'latitude':this.latitude, 'longitude':this.longitude, 'zoom':this.scale};
}
