vue和echarts实现地图航线

vue和echarts实现地图航线

效果图：

第一步：echarts的安装。

npm install echarts --save

第二步：在vue项目中的main.js中进行导入echarts，放在其原型上方便利用。

main.js代码：

import Vue from 'vue'
import App from './App.vue'
const echarts = require("echarts")
Vue.config.productionTip = false
Vue.prototype.$echarts = echarts
new Vue({
  render: h => h(App),
}).$mount('#app')

app.vue中的代码：

<template>
  <div id="app">
    <div ref="mapBox" id="mapBox"></div>
  </div>
</template>

<script>
