[Vuejs]-Set boolean to false when pressing every other key except enter button vue.js

I mean, you could just handle all keyups, and check for the key code, since the passed event should be a regular javascript event like any other.

<input type="text" v-model="msg" class="form-control m-0" placeholder="Filter by tag" @keyup="onKeyup" />

…

methods: {
    onKeyup(event) {
        showTag = (event.which == 13 || event.keyCode == 13)
    },
},
