获取指定格式日期

let date = new Date()

//获取当前时间，格式类似'2023-02-23 15:58:05'
let year = date.getFullYear()
let month = (date.getMonth() + 1).toString().padStart(2,'0')
let day = date.getDate().toString().padStart(2,'0')
let hour = date.getHours().toString().padStart(2,'0')
let min = date.getMinutes().toString().padStart(2,'0')
let sec = date.getSeconds().toString().padStart(2,'0')

let str = ${year}-${month}-${day} ${hour}:${min}:${sec}

console.log(str)
