1.日期字符串转时间戳
// (1) 当前时间
let timestamp = parseInt(new Date().getTime());
// (2) 指定时间
let date = '2015-03-05 17:59';
let timestamp = new Date(date).getTime();
console.log(timestamp )
2.时间戳转换时间
let timestamp = 1553841000000;
let d = new Date(timestamp)
let date = (d.getFullYear()) + "-" +
(d.getMonth() + 1) + "-" +
(d.getDate()) + " " +
(d.getHours()) + ":" +
(d.getMinutes()) + ":" +
(d.getSeconds());
console.log(date)
js日期时间格式化，可直接复制打包成js文件使用
export function formatDate(date, fmt) {
if (/(y+)/.test(fmt)) {
fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length));
}
let o = {
'M+': date.getMonth() + 1,
'd+': date.getDate(),
'h+': date.getHours(),
'm+': date.getMinutes(),
's+': date.getSeconds()
};
for (let k in o) {
if (new RegExp(`(${k})`).test(fmt)) {
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);
}
