js处理时间

function timestampToTime(timestamp) {
let date = new Date(timestamp);
let Y = date.getFullYear() + '-';
let M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
let D = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate()) + ' ';
let h = (date.getHours() < 10 ? '0' + date.getHours() : date.getHours()) + ':';
let m = (date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()) + ':';
let s = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds();
return Y + M + D + h + m + s;
// return Y + M + D;
}
