Reusable clickaway directive for reusable Vue.js components
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-clickaway2
exists. Please check out
the demo before reading further.
Vue-Clickaway2 is a continuation of Vue-Cickaway.
- vue: ^2.0.0
If you need a version for Vue 1, try [email protected]
.
From npm:
$ npm install vue-clickaway2 --save
- 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-clickaway2';
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-clickaway2';
export default {
directives: {
onClickaway: onClickaway,
},
template: '<p v-on-clickaway="away">Click away</p>',
methods: {
away: function() {
console.log('clicked away');
},
},
};
You can pass an argument conataining any HTML DOM Event on the directive in the markup:
<p v-on-clickaway:mousedown="away">Click away</p>
<!-- If you don't pass an argument it'll default to click just like previous versions -->
- Pay attention to the letter case.
onClickaway
turns intov-on-clickaway
, whileonClickAway
turns 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.
