vue-clickout

Reusable clickout directive for reusable Vue.js components. forked from vue-clickaway

Overview

Sometimes you need to detect clicks outside of the element (to close a modal window or hide a dropdown select). There is no native event for that, and Vue.js does not cover you either. This is why vue-clickout exists.

Why not vue-clickaway?

This library is forked from vue-clickaway. The main reason for creating a separate library is lack of some features in the vue-clickaway. for example stop modifier for stopPropagation support and capture for capturing support.

Requirements

• vue: ^2.0.0

Install

$ npm install vue-clickout --save

Usage

1. Make the directive available to your component
2. Define a method to be called
3. Use the directive in the template

The recommended way is to use the mixin:

import { mixin as clickout } from 'vue-clickout'
 
export default {
  mixins: [clickout],
  template: '<p v-on-clickout="out">Click out</p>',
  methods: {
    out: function() {
      console.log('clicked out')
    }
  }
}

If mixin does not suit your needs, you can use the directive directly:

import { directive as onClickout } from 'vue-clickout'
 
export default {
  directives: {
    onClickout: onClickout
  },
  template: '<p v-on-clickout="out">Click out</p>',
  methods: {
    out: function() {
      console.log('clicked out')
    }
  }
}

Caveats

1. Pay attention to the letter case. onClickout turns into v-on-clickout, while onClickOut turns into v-on-click-out.
2. Prior to vue@^2.0, directive were able to accept statements. This is no longer the case. If you need to pass arguments, just do v-on-clickout="() => out(arg1)".
3. There is a common issue with dropdowns (and modals) inside an element with v-on-clickout. Some UI libraries chose to implement these UI elements by attaching the DOM element directly to the body. This makes clicks on a dropped element trigger away handler. To combat that, you have to add an extra check in the handler, for where the event originated from. See #9 for an example.
