使用的是vue2.0，请问.vue文件中如何使用echarts？

Question

我在A.vue文件中的temple标签里写<div id="main"></div>，在script标签里直接写var myChart = echarts.init(document.getElementById('main'))，然后在B.vue文件中import A.vue,然后就报错了,说没有找到main这个dom元素，请问这种情况该如何解决比较好呢？

Answer 1

main.js

import echarts from "echarts"

A.vue
HTML

<div id="charts">
    <div id="main"  :style="{width:'600px',height:'400px'}"></div>
</div>

javascript

     export default{
        data (){
            return {
                msg:"123"
            }
        },
        mounted (){
            var myChart = echarts.init(document.getElementById('main'));
            myChart.setOption({
                title: { text: 'ECharts 入门示例' },
                tooltip: {},
                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]
                }]
            });
        }

    }

let echarts = require('echarts/lib/echarts');
// 引入折现图
require('echarts/lib/chart/line');
// 引入提示框和标题组件
require('echarts/lib/component/tooltip');
require('echarts/lib/component/title');
require('echarts/lib/component/toolbox');
export default{
    data(){
        return {
            chart:null
        }
    },
    
    ready(){
        this.chart = echarts.init(document.querySelector('.echarts'))
        this.chart.setOption({
            grid: {
                show:false,

强烈建议使用highcharts,文档很完整，结构也很清晰，引入也很容易，能满足大多数的图标样式需求，而且在移动端可以很容易的实现响应式的图表。
import Highcharts from 'highcharts'
