   轮播代码如下：
   
   
   // 地图高亮轮播
       mapActive() {
   			const mapData = ['上海', '河北', '山西', '内蒙古', '辽宁', '吉林','黑龙江',  '江苏', '浙江', '安徽', '福建', '江西', '山东','河南', '湖北', '湖南', '广东', '广西', '海南', '四川', '贵州', '云南', '西藏', '陕西', '甘肃', '青海', '宁夏', '新疆', '北京', '天津', '重庆', '香港', '澳门', '台湾'];
         if (!this.chartMap) {
           return
         }
         const dataLength = mapData.length
         // 用定时器控制高亮
         this.carouselTime = setInterval(() => {
           // 清除之前的高亮
           this.chartMap.dispatchAction({
             type: 'downplay',
             seriesIndex: 0,
             // mapIndex: this.mapIndex
           })
           this.mapIndex++
           // 当前下标高亮
           this.chartMap.dispatchAction({
             type: 'highlight',
             seriesIndex: 0,
             mapIndex: this.mapIndex
           })
           this.chartMap.dispatchAction({
             type: 'showTip',
             seriesIndex: 0,
             mapIndex: this.mapIndex
           })
           if (this.mapIndex > dataLength) {
             this.mapIndex = 0
           }
   				console.log('this.chartMap----', this.chartMap)
   				console.log('this.mapIndex----', this.mapIndex)
         }, 3000)
         this.chartMap.on('mouseover', () => {
           // 停止定时器，清除之前的高亮
           clearInterval(this.carouselTime)
           this.carouselTime = null
           this.chartMap.dispatchAction({
             type: 'downplay',
             seriesIndex: 0,
             mapIndex: this.mapIndex
           })
         })
         // 鼠标划出重新定时器开始
         this.chartMap.on('mouseout', () => {
   				clearInterval(this.carouselTime)
           this.carouselTime = null
           this.mapActive()
         })
       },
