vue uses echarts to adaptively report Uncaught TypeError: Cannot read property 'resize' of undefined

Just change _ this.myChart.resize()   to  if (_this.myChart) _this.myChart.resize()  ;.

window.addEventListener("resize", function () {
        // _this.myChart.resize(); // y原先的写法图表自适应的一个方法
        if (_this.myChart) _this.myChart.resize(); //现在的写法
      });
