//自定义时间过滤器
Vue.filter('dateFormat',function(originVal) {
  const dt = new Date(originVal)
  const y = dt.getFullYear()
  //月份不足两位用0补齐
  const m = (dt.getMonth() + 1 +'').padStart(2,'0')
  const d = (dt.getDay() + '').padStart(2,'0')
  const hh = (dt.getHours() + '').padStart(2,'0')
  const mm = (dt.getMinutes() + '').padStart(2,'0')
  const ss = (dt.getSeconds()+ '').padStart(2,'0')

  return `${y}-${m}-${d} ${hh}:${mm}:${ss}`
})
