<template>
  <div>
    <p>当前时间：{{ time }}</p>
  </div>
</template>
<script>
export default {
  data() {
    return {
      time: ''
    }
  },
  mounted() {
    this.getTime()
  },
  methods: {
    getTime() {
      const date = new Date()
      const hours = date.getHours()
      const minutes = date.getMinutes()
      const seconds = date.getSeconds()
      this.time = `${hours}:${minutes}:${seconds}`
      setInterval(() => {
        const date = new Date()
        const hours = date.getHours()
        const minutes = date.getMinutes()
        const seconds = date.getSeconds()
        this.time = `${hours}:${minutes}:${seconds}`
      }, 1000)
    }
  }
}
</script>
