vue-directive-clickout

a small Vue 2.0 directive to detect clicks outside of an element and run a callback function.

Installation

NPM

Install the package from npm

npm install --save vue-directive-clickout

Load it in your main js file and register it:

import VueDirectiveClickout from 'vue-directive-clickout'

// register it globally
Vue.directive('clickout', VueDirectiveClickout)

// you can also register it locally in individual components only:
export default {
  // other component options...
  directives: {
    'clickout': VueClickoutDirective
  }
}

Via script tag

Insert the script tag after you import Vue:

<script src="https://unpkg.com/vue@next/dist/vue.js"></script>

It will be automatically registered globally (with Vue.component) as a directive with the name v-clickout

Usage

Simply add the directive to any element for which you want to register clicks outside of (e.g. a modal window)

<div v-clickout="close" class="modal-window">

</div>

and provide a method by that name in your component. The method receives the event as an argument, just like it would for a normal click event.

export default {
  // ... other component options
  methods: {
    close(event) {
      console.log(event.target)
    }
  }
}

The `.bubble` modifier

By default, click events inside of or on the element that the directive is defined on do not trigger the callback.

You can change this behaviour by adding the .bubble modifier:

<div v-clickout.bubble="close" class="modal-window">
  <button>Click Me</button>
  <!-- Clicking this button  (or anywhere inside of the div) will call the "close" callback -->
</div>

This may be useful to have e.g. an image modal that closes when you click anywhere, including the image.

The `.visible` modifier

If you add the .visible modifier, the callback will only be run if the element is visible*. This is usefull if you can't toggle a v-clickout element with v-if (which would remove the element from the document, and therefore the directive & event) and instead have to rely on v-show (which adds display: none to the style attribute but keeps the element in the DOM) or something similar.

(*) This means: the computed Style of the element has neither display: none nor visibility: hidden

<div v-clickout.visible="close" style="display:none">
  <!-- Clicking ouside of this element will *not* trigger the callback because the element is not visible -->
  <button>Click Me</button>
</div>

Limitations

You must pass a component method as a callback to this directive. You can't use an expression. For example, the following will not work:

<div v-clickout.bubble="$emit('close')" class="modal-window">
  <!-- content -->
</div>

For any expression that does not resolve to a function, like the above example, this directive will log a warning to a console (in development mode).
