Vue 2.x directive to react on events outside of an element

Vue 2.x directive to react on events outside of an element

vue-outside-events

Vue 2.x directive to react on events outside of an element without stopping the event's propagation.

Works well for handling clicks outside of menus and popups. Can handle any DOM event or CustomEvent. Also able to capture jQuery events.

Install

npm install --save vue-outside-events

Demos

Use

Modular

import Vue from 'vue'
import vOutsideEvents from 'vue-outside-events'

Vue.use(vOutsideEvents)
<script>
  export default {
    methods: {
      onClickOutside (e, el) {
        console.log('onClickOutside');
        console.log('click heard outside element: ', el);
        console.log('element clicked: '. e.target);
        console.log('event: ', e);
      },
      onMouseOutside (e, el) {
        console.log('onMouseOutside');
        console.log('mouse moved outside element: ', el);
        console.log('element mouse moved over: '. e.target);
        console.log('event: ', e);
      }
    }
  };
</script>

<template>
  <div v-click-outside="onClickOutside"></div>
  <div v-mousemove-outside="onMouseOutside"></div>
</template>

Scripts

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.2.6/vue.min.js" type="text/javascript"></script>
<script src="js/v-outside-events.min.js" type="text/javascript"></script>

<div id="app">
  <div v-click-outside="onClickOutside"></div>
  <div v-mousemove-outside="onMouseOutside"></div>
</div>

<script>
	new Vue({
		el: '#app',
		methods: {
			onClickOutside (e, el) {
				console.log('onClickOutside');
				console.log('click heard outside element: ', el);
				console.log('element clicked: '. e.target);
				console.log('event: ', e);
			},
			onMouseOutside (e, el) {
				console.log('onMouseOutside');
				console.log('mouse moved outside element: ', el);
				console.log('element mouse moved over: '. e.target);
				console.log('event: ', e);
			}
		}
	});
</script>

Modifiers

Add the jquery modifier to allow the directive to handle jQuery triggering of custom events. jQuery must be present in the window for this to work.

<div id="myDiv1" v-event-outside="{ name: 'onFoo', handler: onFooOutside }"></div>
<div id="myDiv2" v-event-outside.jquery="{ name: 'onFoo', handler: onFooOutside }"></div>

<script>
	$(document).trigger("onFoo"); // onFooOutside will be called for #myDiv2, but not #myDiv1

	var event = document.createEvent('Event');
	event.initEvent('onFoo', true, true);
	document.dispatchEvent(event); // onFooOutside will be called for #myDiv1 and #myDiv2
</script>
