vue.js写一个三分钟的倒计时，格式为02:59:99

<template>
  <div>
    <div>
    {
   
   { t_Minutes }} : {
   
   { t_Seconds }} : {
   
   { t_Milliseconds }}
    </div>
    <div v-if="time <= 0">时间到了！</div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      time: 180,
    };
  },
  computed: {
    t_Minutes() {
      const minutes = Math.floor(this.time / 60);
      return minutes.toString().padStart(2, '0');
    },
    t_Seconds() {
      const seconds = Math.floor(this.time % 60);
      return seconds.toString().padStart(2, '0');
    },
    t_Milliseconds() {
      const milliseconds = Math.floor((this.time % 1) * 100);
      return milliseconds.toString().padStart(2, '0');
    },
  },
  mounted() {
    setInterval(this.updateTime, 1);
  },
  methods: {
    updateTime() {
      if (this.time > 0) {
        this.time -= 0.004;
      }
    },
  },
};
</script>
