vue如何监听键盘事件？

@keyup.

<template>  <input ref="myInput" type="text" value="hello world" autofocus @keyup.enter="handleKey"></template><script>  export default {    methods: {      handleKey(e) {        console.log(e)      }    }  }</script>

addEventListener

<script>  export default {    mounted() {      document.addEventListener('keyup', this.handleKey)    },    beforeDestroy() {      document.removeEventListener('keyup', this.handleKey)    },    methods: {      handleKey(e) {        console.log(e)      }    }  }</script>
