效果展示

在vue lic 的components資料夾下，新建元件CurrentTime.vue
直接上元件程式碼：

<template>
  <div>
      {{ nowDate + ' ' + nowTime + ' ' + nowWeek }}
  </div>
</template>

<script>
export default {
  name: 'CurrentTime',
    data() {
        return {
            nowDate:
 
 "",    // 當前日期
            nowTime: "",    // 當前時間
            nowWeek: ""     // 當前星期
        };
    },
    methods: {
        currentTime() {
            setInterval(this.getDate, 500);
        },
        getDate: function() {
            var _this = this;
            let yy =
 
 new Date().getFullYear();
            let mm = new Date().getMonth() + 1;
            let dd = new Date().getDate();
            let week = new Date().getDay();
            let hh = new Date().getHours();
            let mf =
                new Date().getMinutes() < 10
                    ? "0"
 
 + new Date().getMinutes()
                    : new Date().getMinutes();
            if (week == 1) {
                this.nowWeek = "星期一";
            } else if (week == 2) {
                this.nowWeek = "星期二";
            } else if (week == 3) {
                this.nowWeek = "星期三";
            } else if (week == 4) {
                this.nowWeek = "星期四";
            } else if (week == 5) {
                this.nowWeek = "星期五";
            } else if (week == 6) {
                this.nowWeek = "星期六";
            } else {
                this.nowWeek = "星期日";
            }
            _this.nowTime = hh + ":" + mf;
            _this.nowDate = yy + "/" + mm + "/" + dd;
        }
    },
    mounted() {
        this.currentTime();
    },
    // 銷燬定時器
    beforeDestroy: function() {
        if (this.getDate) {
            console.log("銷燬定時器")
            clearInterval(this.getDate); // 在Vue例項銷燬前，清除時間定時器
        }
    }
};
</script>

新增元件
在App.vue中，新增以下程式碼

<script>
import CurrentTime from './components/currentTime.vue'

export default {
    components: {
    CurrentTime
  },
}
</script>

且在app中新增 <current-time></current-time>
