2、路由模式

import Vue from 'vue'
import Router from 'vue-router'
import { asyncRouterMap } from '@/config/router.config'

// hack router push callback
const originalPush = Router.prototype.push
Router.prototype.push = function push (location, onResolve, onReject) {
  if (onResolve || onReject) return originalPush.call(this, location, onResolve, onReject)
  return originalPush.call(this, location).catch(err => err)
}
Vue.use(Router)

const $router = new Router({
  // mode: 'history',
  base: process.env.BASE_URL,
  routes: asyncRouterMap,
  scrollBehavior (to, from, savedPosition) {
    return { x: 0, y: 0}
  }
})
// 解决Loading chunk (\d)+ failed问题
$router.onError((error) => {
  const pattern = /Loading chunk (\d)+ failed/g;
  const isChunkLoadFailed = error.message.match(pattern);
  if(isChunkLoadFailed){
    // 用路由的replace方法，并没有相当于F5刷新页面，失败的js文件并没有从新请求，会导致一直尝试replace页面导致死循环，而用 location.reload 方法，相当于触发F5刷新页面，虽然用户体验上来说会有刷新加载察觉，但不会导致页面卡死及死循环，从而曲线救国解决该问题
    location.reload();
    // const targetPath = $router.history.pending.fullPath;
    // $router.replace(targetPath);
  }

});
export default $router;

3、悬浮球页面

功能：右侧菜单事件，拖拽，双击进入主页

<template>
  <div class="content_body" >
    <div class="ball">
      <div @dblclick="goMainPage"  >
        <span style="color: transparent">1</span>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  name: "ball",
  data () {
    return {
    }
  },
  created() {
    let win;
    let biasX ;
    let biasY;
    if (navigator.userAgent.indexOf('Electron') != -1) {
      const remote = require('electron').remote
      const {ipcRenderer: ipc} = require('electron');
      win= remote.getCurrentWindow();
      biasX = 0;
      biasY = 0;
      let that = this;
      document.addEventListener('mousedown', function (e) {
        switch (e.button) {
          case 0:
            biasX = e.x;
            biasY = e.y;
            document.addEventListener('mousemove', moveEvent);
            break;
          case 2:
            ipc.send('createSuspensionMenu')
            break;
        }
      });

      document.addEventListener('mouseup', function () {
        biasX = 0;
        biasY = 0;
        document.removeEventListener('mousemove', moveEvent)
      });
    }

    function moveEvent(e) {
      if (navigator.userAgent.indexOf('Electron') != -1) {
        if(win!=null){
          win.setPosition(e.screenX - biasX, e.screenY - biasY)
        }
      }
    }
  },
  methods: {
    goMainPage () {
