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);
      },
      onFoo (e, el, extras) {
        console.log('onFoo');
        console.log('fooEvent happened outside element:', el);
        console.log('element that triggered foo:', e.target);
        console.log('event:', e);
        console.log('extras:', extras);
        console.log('bar:', extras.bar);
      }
    }
  };
</script>

<template>
  <div v-click-outside="onClickOutside"></div>
  <div v-mousemove-outside="onMouseOutside"></div>
  <div v-event-outside="{ name: 'fooEvent', handler: onFoo, bar: 'baz' }"></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 v-event-outside="{ name: 'fooEvent', handler: onFoo, bar: 'baz' }"></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('bar:', extras.bar);
      }
    }
  });
</script>

Events

Event Event Name Directive Binding
Click click v-click-outside ="handlerName"
Double-Click dblclick v-dblclick-outside ="handlerName"
Focus focusin v-focus-outside ="handlerName"
Blur focusout v-blur-outside ="handlerName"
Mouse Over / Enter mouseover v-mouseover-outside ="handlerName"
Mouse Move mousemove v-mousemove-outside ="handlerName"
Mouse Up mouseup v-mouseup-outside ="handlerName"
Mouse Down mousedown v-mousedown-outside ="handlerName"
Mouse Out mouseout v-mouseout-outside ="handlerName"
Key Down keydown v-keydown-outside ="handlerName"
Key Up keyup v-keyup-outside ="handlerName"
Key Press keypress v-keypress-outside ="handlerName"
Change change v-change-outside ="handlerName"
Select select v-select-outside ="handlerName"
Submit submit v-submit-outside ="handlerName"
Custom "eventName" v-event-outside ="{ name: 'eventName', handler: handlerName }"

Extras

Add additional key/value pairs to the custom event to pass data to the event handler.

<div v-event-outside="{ name: 'fooEvent', handler: onFoo, bar: 'baz' }"></div>
onFoo (e, el, extras) {
  console.log('onFoo');
  console.log('fooEvent happened outside element:', el);
  console.log('element that triggered foo:', e.target);
  console.log('event:', e);
  console.log('extras:', extras);
  console.log('bar:', extras.bar);
}

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>
