vue 自定義報警元件

1.自定義報警元件

Alarm.vue

<!-- 報警 元件 -->
<template>
  <div class="alarm">
    <!-- <video src="../assets/mp3/6705.mp3" controls="controls">
    您的瀏覽器不支援 video 標籤。
    </video> -->

    <audio id="myAudio" loop>
      <source :src="url" type="audio/mpeg">
    </audio>

    <!-- <audio id="myAudio" loop>
      <source v-if="number == 2370" src="../assets/mp3/2370.mp3" type="audio/mpeg">
      <source v-if="number == 4031" src="../assets/mp3/4031.mp3" type="audio/mpeg">
      <source v-if="number == 6705" src="../assets/mp3/6705.mp3" type="audio/mpeg">
    </audio> -->
  </div>
</template>

<script>
  /**
   * audio 屬性詳解
   * controls 顯示或隱藏使用者控制介面
   * autoplay 是否自動播放(載入時播放,僅播放一次)
   * loop 是否迴圈播放
   * preload 是否預載入
   */
  export default {
    props: {
      onOff: { // 報警開關
        type: Boolean,
        default: false
      },
      number: {
        type: Number,
        default: 6705
      }
    },
    data() {
      return {
        url: require('../assets/mp3/6705.mp3')
      }
    },
    watch:{
      onOff: {
        handler: function (val, oldVal) {
          if(val){
            document.getElementById('myAudio').play();
          }else{
            document.getElementById('myAudio').pause();
          }
        },
        deep: true
      }
    },
    methods: {
      //
    }
  }
</script>

<style lang="less" scoped>
  .alarm {
