vue2.0 解决抽取公用js的问题

export default {
 install(Vue, options) {
  Vue.prototype.formatDuring = function (mss) {
   var days = parseInt(mss / (1000  60  60  24));
   var hours = parseInt((mss % (1000  60  60  24)) / (1000  60  60));
   var minutes = parseInt((mss % (1000  60  60)) / (1000  60));
   var seconds = (mss % (1000  60)) / 1000;
   return days + " 天 " + hours + " 小时 " + minutes + " 分 " + Math.round(seconds) + " 秒 ";
  }
 }

}

// 引入公用js
import utils from '../static/js/utils.js' 
Vue.use(utils); 

// 共通类
let monUtil = {
};
 
monUtil.openLogin = function (terminal) {
  console.log("i am is js mathod;" + terminal);
};
 
export default monUtil;
