头部加入babel-polyfill

//适配IE低版本，Web-API
import "babel-polyfill";
import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import moment from "moment";
import ElementUI from "element-ui";

new Vue({

    render: h => h(App),
    mounted() {
        document.dispatchEvent(new Event("render-event"));
    }
