下面我就为大家分享一篇js实现把时间戳转换为yyyy-MM-dd hh:mm 格式(es6语法),具有很的参考价值,希望对大家有所帮助

如下所示:

function formatDate(date,fmt) {
 if(/(y+)/.test(fmt)){
 fmt = fmt.replace(RegExp.$1,(date.getFullYear()+'').substr(4-RegExp.$1.length));
 }
 let o = {
 'M+':date.getMonth() + 1,
 'd+':date.getDate(),
 'h+':date.getHours(),
 'm+':date.getMinutes(),
 's+':date.getSeconds()
 };

 // 遍历这个对象
 for(let k in o){
 if(new RegExp(`(${k})`).test(fmt)){
  // console.log(`${k}`)
  console.log(RegExp.$1)
  let str = o[k] + '';
  fmt = fmt.replace(RegExp.$1,(RegExp.$1.length===1)?str:padLeftZero(str));
 }
 }
 return fmt;
};

function padLeftZero(str) {
 return ('00'+str).substr(str.length);
}
Copy after login

let TimeNow = 1514374627*1000
let newTime = new Date(TimeNow)

formatDate(newTime,'yyyy-MM-dd hh:mm')   //2017-12-27 19:37

上面是我整理给大家的,希望今后会对大家有帮助。
