Add shortcuts by listening to events on the document, anywhere
This is the version for Vue 3, if you are looking for the Vue 2 version, take a look at the v1 branch
yarn add vue-global-events
npm install vue-global-eventsThanks to Vue’s event modifiers, handling events is extremely easy however, you’re limited to DOM element events.
We decided to change that, so now you can register global events (for example application shortcuts) just like you would listen to events on a component. No need to worry about removing them either. You can toggle the events with a single v-if. Works with SSR too.
import { GlobalEvents } from 'vue-global-events'
// register globally
app.component('GlobalEvents', GlobalEvents)
// or locally
export default {
components: { GlobalEvents },
// rest of your component
}After that you can register global events like this:
<GlobalEvents
v-if="listenersConnected"
@keyup.ctrl.tab="nextTab"
@keyup.ctrl.shift.tab="previousTab"
@keyup.space="pause"
@contextmenu="openMenu"
/>Target element where addEventListener is called on. It's a String that refers to a global variable like document or window. This allows you to add events to the window instead of document.
- type:
String - default:
'document'
Warning: This prop is not reactive. It should be provided as a static value. If you need it to be reactive, add a key attribute with the same value:
<GlobalEvents :target="target" :key="target" />Function to prevent any event from being executed based on anything related to the event like the element that triggered it, the name, or the handler.
- type:
Function - default:
() => true
event: Native Event Objecthandler: method passed toGlobalEventscomponenteventName: event name that was attached to the target (See above)
filter should return false to prevent the execution of a handler. For example, you can avoid the calls if the event is triggered by an <input>:
<GlobalEvents
:filter="(event, handler, eventName) => event.target.tagName !== 'INPUT'"
@keyup.prevent.space.exact="nextTab"
/>In the example above event would be the native keyup Event Object, handler would be the method nextTab and eventName would be the string keyup.
- Always
.preventevents with.ctrland other modifiers as browsers may be using them as shortcuts. - Do not use shortcuts that are used by the system or that the browser does not allow you to
.preventDefault(). The list includesCtrl+Tab/Cmd+Tab,Ctrl+W/Cmd+W. You can find more information in this StackOverflow answer. - Prefer using actual characters to keyCodes whenever possible:
@keydown.+for detecting the plus sign. This is important because symbols and numbers on the digit row will provide different keyCodes depending on the layout used. - About using
keyupwith modifiers like.ctrlor.shift: the keyup event is triggered when a key is released and that's also when theevent.ctrlKeyis checked, which if you just released, will be false. This is becausectrl,shiftandaltare checked differently. If you want to trigger on thekeyupevent of a modifier, you need to use its keycode (check it here. For example, for thectrlkey, that would be:@keyup.17. You can also use the advice above this one to provide it a name like ctrlkey.
