js 時間戳轉爲日期格式

var timestamp1 = 1576741436;//時間戳

var timestamp2 = new Date(parseInt(timestamp1) * 1000);

console.log(timestamp2 ); //Thu Dec 19 2019 15:43:56 GMT+0800 (中國標準時間)

var timestamp3 = timestamp2.toLocaleDateString().replace(/\//g, "-") + " " + timestamp2.toTimeString().substr(0, 8);

console.log(timestamp3 );// "2019-12-19 15:43:56​​​​​​​"
