JS 獲取當前時間,格式為年月日時分秒

let getNowFormatDate = () => { //獲取當前時間

  let date = new Date();

  let seperator1 = "."; //年月日之間的分隔

  let seperator2 = ":"; //時分秒之間的分隔

  let month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1; //獲取月,如果小於10,前面補個0

  let strDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate(); //獲取日,如果小於10,前面補個0

  let strHours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(); //獲取小時,如果小於10,前面補個0

  let strMinutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(); //獲取分,如果小於10,前面補個0

  let strSeconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(); //獲取秒,如果小於10,前面補個0

  let currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate +

​    " " + strHours + seperator2 + strMinutes +

​    seperator2 + strSeconds; //拼接一下

  return currentdate; //返回

}



let time = getNowFormatDate(); //打印輸出:2020.04.02 12:34:56
