• 引入 import * as echarts from 'echarts';

• 页面 <div id="main" style="width: 600px; height: 400px"></div>

• js

  mounted () {
  this.echartsInit();
  },
  methods: {
  echartsInit () {
    echarts.init(document.getElementById('main')).setOption({
      title: {
        text: 'ECharts 入门示例'
      },
      tooltip: {},
      legend: {
        data: ['销量']
      },
      xAxis: {
        data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
      },
      yAxis: {},
      series: [
        {
          name: '销量',
          type: 'bar',
          data: [5, 20, 36, 10, 10, 20]
        }
      ]
    });
  }
  }

注意

调用 echarts 如果控制台出现报错 Cannot read properties of undefined (reading ‘init‘) 是因为引入错误导致。

import echarts from 'echarts'; // 错误的引入
import * as echarts from 'echarts';//echarts 官网引入方法
