1.页面传值：

源页面：

 showScreen(){
　　let routeData = this.$router.resolve({path:'/company-show',query:{companyId:this.companyId,year:this.year}});
　　window.open(routeData.href, '_blank');
 }

 

目标页面：

 mounted() {
      this.companyId = this.$route.query.companyId;
      this.year = this.$route.query.year;
    },

2.定时器：

 mounted() {
     this.timer=setInterval(this.loadIndustryOrderChart,30000);
    },

beforeDestroy(){
  clearInterval(this.timer);
}

3.引入echarts

const echarts = require('echarts')
