在使用vue绘图的时候，我设置间隔时间进行绘制，控制台一直警告 [ECharts] There is a chart instance already initialized on the dom.
查看代码是因为获取了两次dom进行了初始化
mounted() { this.mychart = echarts.init(this.$refs.charts);//此处和下边的initChart方法里重复了 //实时获取，离开销毁 let currentTimer = setInterval(() => { console.log(this.maxList) this.getByIdMax(); }, 1000); this.$once("hook:beforeDestroy", () => { clearInterval(currentTimer); currentTimer = null; console.log("高温预警卡片销毁了"); }); }, methods: { //图表初始化 initChart() { //初始化echarts实例(与上方重复获取dom导致出错，删掉即可) let lineCharts = echarts.init(this.$refs.charts);
