Vue.use和Vue.prototype的区别

import Vue from 'vue'
import App from './App.vue'
import router from './router'

// 引入echarts
import echarts from 'echarts'
import 'echarts/map/js/china.js';
Vue.prototype.$echarts = echarts

// 将自动注册所有组件为全局组件
import dataV from '@jiaminghi/data-view'
Vue.use(dataV)

var install = function(Vue) {
    Object.defineProperties(Vue.prototype, {
        $Plugin: {
            value: function() { console.log('I am a plugin') }
        }
    })
}
module.exports = install

// 测试插件
import Plugin from "./plugin/plugin"
Vue.use(Plugin)

this.$Plugin()

export const Plugin1 = (parameter1) => {
    console.log(parameter1)
}

import { Plugin1 } from "./plugin/plugin"
Vue.prototype.Plugin1 = Plugin1

this.Plugin1("111")
