《1》在src文件夹下新建文件夹prototypefns--------在此文件夹创建util.js,
《2》在prototypefns下新建文件夹jsTime--------在此文件夹下新建datatime.js

export { DateToUnix, UnixToDate, NumBerToHanZi, DownTime }
util.js
import { DateToUnix, UnixToDate, NumBerToHanZi, DownTime } from ‘@/prototypefns/jsTime/datatime‘;
export default{
install (Vue,options) {
/*时间转换器*/
Vue.prototype.dateToUnix = DateToUnix;//转换时间戳
Vue.prototype.unixToDate = UnixToDate;//转换时间
Vue.prototype.downTime = DownTime;//倒计时
Vue.prototype.numBerToHanZi = NumBerToHanZi;//转汉字
}
}
2.在main.js引入，并全局注册
import util from ‘@/prototypefns/util‘
Vue.use(util);
3.应用
