时间戳转string string 转时间 获取时间

1、时间戳转时间

function formatDateDay(value,type='-') {

    if(value) {
        let date = new Date(parseInt(value) * 1000)
        let Y=date.getFullYear()
        let M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1)
        let D = date.getDate()
        let h = date.getHours()
        let m = date.getMinutes()
        D=parseInt(D)<10 ? '0'+D: D
        h=parseInt(h)<10 ? '0'+h: h
        m=parseInt(m)<10 ? '0'+m: m
        return Y+type+M+type+D
    }else{
        return '暂无信息'
    }
}

2、时间戳 时间差 是否显示时分

function getTimeDiff(value,timeT=0,needTime = false){

   let date = value===''?new Date():new Date(parseInt(value) * 1000)
   date.setDate(date.getDate() + timeT);//如果有时间差
   let Y = date.getFullYear()
   let M =  date.getMonth() + 1
   let D = date.getDate()
   let h = date.getHours()
   let m = date.getMinutes()
   M =  parseInt(M) < 10 ? '0' + M : M
   D = parseInt(D) < 10 ? '0' + D : D
   h = parseInt(h) < 10 ? '0' + h : h
   m = parseInt(m) < 10 ? '0' + m : m
   if(needTime){
      return Y + '-' + M + '-' + D + ' ' + h + ':' + m
   } else {
      return Y + '-' + M + '-' + D
   }
}

3、时间转时间戳

function dateToTimestamp(date){
     if(date){
      date = date.replace(/\-/g, "/")
      date = new Date(date).getTime()/1000
      return date
     }else{
         return 0;
     }
}
