在.vue 文件中引入.js文件怎么调用

export default{
  //时间戳转换为正常时间格式
  timeStampChange:function(time){
    let p = ‘‘;
    var date = new Date(time); // 获取时间戳
    let y = date.getFullYear();
    let MM = date.getMonth() + 1;
        MM = MM < 10 ? (‘0‘ + MM) : MM;
    let d = date.getDate();
        d = d < 10 ? (‘0‘ + d) : d;
    let h = date.getHours();
        h = h < 10 ? (‘0‘ + h) : h;
    let m = date.getMinutes();
        m = m < 10 ? (‘0‘ + m) : m;
    let s = date.getSeconds();
        s = s < 10 ? (‘0‘ + s) : s;
    p = y + ‘-‘ + MM + ‘-‘ + d + ‘ ‘ + h + ‘:‘ + m + ‘:‘ + s;
    return p;
  }
}

import timeStampChanges from ‘../../../assets/js/timeStampChange‘;
 
this.recordInformation.map(function(item,index){
  item.time = timeStampChanges.timeStampChange(item.time);
})
