Reusable clickaway directive for reusable Vue.js components
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-clickaway exists. Please check out the demo before reading further.
Requirements
- vue: ^2.0.0
If you need a version for Vue 1, try [email protected].
Install
From npm:
$ npm install vue-clickaway --save
From CDN, chose the one you prefer:
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue-clickaway.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue-clickaway/2.2.2/vue-clickaway.min.js"></script>
<script src="https://cdn.rawgit.com/simplesmiler/vue-clickaway/2.2.2/dist/vue-clickaway.min.js"></script>
Usage
- Make the directive available to your component
- Define a method to be called
- Use the directive in the template
The recommended way is to use the mixin:
import { mixin as clickaway } from 'vue-clickaway';
export default {
mixins: [ clickaway ],
template: '<p v-on-clickaway="away">Click away</p>',
methods: {
away: function() {
console.log('clicked away');
},
},
};
If mixin does not suit your needs, you can use the directive directly:
import { directive as onClickaway } from 'vue-clickaway';
export default {
directives: {
onClickaway: onClickaway,
},
template: '<p v-on-clickaway="away">Click away</p>',
methods: {
away: function() {
console.log('clicked away');
},
},
};
Caveats
- Pay attention to the letter case.
onClickawayturns intov-on-clickaway, whileonClickAwayturns intov-on-click-away. - Prior to
vue@^2.0, directive were able to accept statements. This is no longer the case. If you need to pass arguments, just dov-on-clickaway="() => away(arg1)". - There is a common issue with dropdowns (and modals) inside an element with
v-on-clickaway. 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.
