  <!-- 1. Import the Vue package-->

  <!-- 2. Create an area to control -->
  <div id="app">

    <input type="button" value="Stop" @click="stop">
    <h4>{{ count }}</h4>
  </div>
 
  <script>
    var vm = new Vue({
      el: '#app',
      data: {
        count: 0,
        intervalId: null
      },
      methods: {
        add() {
          // Timer in progress, exit function if (this.intervalId != null) { 
            return 
          };
          // The timer is empty, operation this.intervalId = setInterval(() => {
            this.count += 1
          }, 400)
        },
        // Stop the timer stop() { 
          clearInterval(this.intervalId) // Clear timer this.intervalId = null; // Set to null 
        }
      }
    })
  </script>
</body>

Previously, the editor collected a component for starting timing. This component can be directly introduced into the project for use. Thank you for sharing.

 <template>
    <div class="timer">
    <div ref="startTimer"></div>
    </div>
    </template>
    <script>
    export default {
    name: 'Timer',
    data () {
    return {
    timer: "",
    content: "",
    hour: 0,
    minutes: 0,
    seconds: 0
    }
    },
    created () {
    this.timer = setInterval(this.startTimer, 1000);
    },
    destroyed () {
    clearInterval(this.timer);
    },
    
    methods: {
    startTimer () {
    this.seconds += 1;
    if (this.seconds >= 60) {
    this.seconds = 0;
    this.minute = this.minute + 1;
    }
    
    if (this.minute >= 60) {
    this.minute = 0;
    this.hour = this.hour + 1;
    }
    this.$refs.startTimer.innerHTML = (this.minutes < 10 ? '0' + this.minutes : this.minutes) + ':' + (this.seconds < 10 ? '0' + this.seconds : this.seconds);
    }
    }
    }
    </script>
    <style>
</style>
