时间戳转换vue

1.格式化时间 

<p>{{formattedTime('1712054698000')}}</p>

const formattedTime = (time: any) => {

    const date = new Date(time)

    const year = date.getFullYear()

    const month = String(date.getMonth() + 1).padStart(2, '0')

    const day = String(date.getDate()).padStart(2, '0')

    const hours = String(date.getHours()).padStart(2, '0')

    const minutes = String(date.getMinutes()).padStart(2, '0')

    const seconds = String(date.getSeconds()).padStart(2, '0')

    return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`

}

2.获取开始时间和结束时间中间的时长

<p>{{setTime('1712052379000','1712053006000')}}</p>
const getTime = (startTime: any, endTime: any) => {
	const start: any = new Date(startTime)
	const end: any = new Date(endTime)
	let diff: any = end - start

    //年
    const years = Math.floor(diff / (1000 * 60 * 60 * 24 * 365.25)).toString().padStart(2, '0');  
    diff %= 1000 * 60 * 60 * 24 * 365.25;  
    //月
    const months = Math.floor(diff / (1000 * 60 * 60 * 24 * 30)).toString().padStart(2, '0');  
    diff %= 1000 * 60 * 60 * 24 * 30;  
    //日
    const days = Math.floor(diff / (1000 * 60 * 60 * 24)).toString().padStart(2, '0');  
    diff %= 1000 * 60 * 60 * 24;  
    //时
	const hours: any = Math.floor(diff / (1000 * 60 * 60)).toString().padStart(2, '0')
	diff %= 1000 * 60 * 60
    //分
	const minutes: any = Math.floor(diff / (1000 * 60)).toString().padStart(2, '0')
	diff %= 1000 * 60
    //秒
	const seconds: any = Math.floor(diff / 1000).toString().padStart(2, '0')

	return `${years}:${months}:${days} ${hours}:${minutes}:${seconds}`
}

//.toString().padStart(2, '0')转换为字符串补零

3.获取n小时以后的时间

//value是要加多少个小时
const addHours = (value:any) => {
	const time: any = value
	const newDate = new Date(time.replace(/-/g, '/'))
	newDate.setHours(newDate.getHours() + n)
	return newDate
}
