  },

 methods: {
    // 格式化时间
    dataFormat(date) {
      // date是传入的时间
      let d = new Date(date)
      let month = d.getMonth() + 1 < 10 ? '0' + (d.getMonth() + 1) : d.getMonth() + 1
      let day = d.getDate() < 10 ? '0' + d.getDate() : d.getDate()
      let hours = d.getHours() < 10 ? '0' + d.getHours() : d.getHours()
      let min = d.getMinutes() < 10 ? '0' + d.getMinutes() : d.getMinutes()
      let sec = d.getSeconds() < 10 ? '0' + d.getSeconds() : d.getSeconds()
