echarts地图轮播markpoint-自用记录📝

echarts地图轮播markpoint

正常添加echarts地图后，添加markpoint图层

 //引入echarts 注册地图 略过 只展示关键代码

轮播代码如下：

思路是对当前高亮节点进行取消高亮操作，然后在高亮下一个节点

需要注意seriesIndex 可以通过在鼠标移入事件中添加打印信息获取

//该段代码在echarts初始化之后调用即可
startLunbo () {
        if (this.intervalId) {
          clearInterval(this.intervalId)
          this.intervalId = null
        }
        this.intervalId = setInterval(() => {
          this.myMapChart.dispatchAction({
            type: 'downplay',
            seriesIndex: 1,
            dataIndexInside: this.lunboId === 0 ? 8 : this.lunboId - 1, //和上面的代码片段中data的长度有关
          })
          this.myMapChart.dispatchAction({
            type: 'highlight',
            seriesIndex: 1,
            dataIndexInside: this.lunboId,
          })
          this.toolIdx = this.lunboId
          this.lunboId++
          if (this.lunboId > 8) { //和上面的代码片段中data的长度有关
            this.lunboId = 0
          }
        }, 2500)
      }

其中鼠标的移入移出事件 自行完成即可
