vue时间戳格式化

两个方法：

timestampToTime (row, column) {
        var date = new Date(row.buytime) //时间戳为10位需*1000，时间戳为13位的话不需乘1000
        var Y = date.getFullYear() + '-'
        var M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-'
        var D = date.getDate() + ' '
        var h = date.getHours() + ':'
        var m = date.getMinutes() + ':'
        var s = date.getSeconds()
        return Y+M+D+h+m+s
        // console.log(timestampToTime (1533293827000))
      timestampToTime (row) {
        let date = new Date(row.selltime + 8 * 3600 * 1000);
        return date
          .toJSON()
          .substr(0, 19)
          .replace('T', ' ')
          .replace(/-/g, '-');
      },
