vue2 new Date() 转换为年月日时分秒以及星期几

new Date()

前言

在vue2中使用new Date() 转换为年月日时分秒以及星期几

代码如下（示例）：

timeFormate (timeStamp) {
      let y = new Date(timeStamp).getFullYear().toString()
      let M = new Date(timeStamp).getMonth() + 1 < 10 ? '0' + (new Date(timeStamp).getMonth() + 1) : new Date(timeStamp).getMonth() + 1
      let d = new Date(timeStamp).getDate() < 10 ? '0' + new Date(timeStamp).getDate() : new Date(timeStamp).getDate()
      let h = new Date(timeStamp).getHours() < 10 ? '0' + new Date(timeStamp).getHours() : new Date(timeStamp).getHours()
      let m = new Date(timeStamp).getMinutes() < 10 ? '0' + new Date(timeStamp).getMinutes() : new Date(timeStamp).getMinutes()
      let s = new Date(timeStamp).getSeconds() < 10 ? '0' + new Date(timeStamp).getSeconds() : new Date(timeStamp).getSeconds()
      let w = new Date(timeStamp).getDay().toString()
      switch (w) {
        case '1':
          w = '一'
          break
        case '2':
          w = '二'
          break
        case '3':
          w = '三'
          break
        case '4':
          w = '四'
          break
        case '5':
          w = '五'
          break
        case '6':
          w = '六'
          break
        default:
          w = '日'
      }
      this.nowTime = y + '年' + M + '月' + d + '日' + '  ' + '星期' + w + '  ' + h + ':' + m + ':' + s
    },
    nowTimes () {
      this.timeFormate(new Date())
      this.dateTimer = setInterval(this.nowTimes, 1000)
    },

代码如下（示例）：

mouted () {

      this.nowTimes()
},
beforeDestroy () {
    if (this.dateTimer) {
      clearInterval(this.dateTimer)
    }
}
