vuejs: @keyup.esc on div element is not working

Question

I\'m expecting that \'close\' event is fired when I\'m clicking ESC button being on \"shadow-modal\" div, but it\'s not happening

vue 2.5.13, any ideas why?

While DmitrySemenov solution works for me it's not the best solution when you have multiple modals on the page. I tried it and I discovered it fires close event for every modal.

I think the best way to do it is registering a "keyup" event when the modal is shown and deregistering it after hide. It gives you an advantage because the event is registered only when it's needed. To do it you need to add a watcher for "show" property:

  props: {
    show: {
      type: Boolean,
      default: false
    }
  },
  watch: {
    show() {   
      if (this.show === false) {
        window.removeEventListener("keyup", this.onEscapeKeyUp);
      } else {
        window.addEventListener("keyup", this.onEscapeKeyUp);
      }
    }
  },
  methods: {
    onEscapeKeyUp(event) {
      if (event.which === 27) {
        this.$emit("close");
      }
    }
  }

The modal should have v-if="show" that controls modal's visibility:
