2023-12-01

Version 2.0.0+ potentially has breaking changes. Please take a look at the changelog below:

Using ResizeObserver instead of MutationObserver
Using transition states to coordinate modal & overlay transitions (instead of delays)
Using prettier
Overlay is not a parent of the modal anymore (now has independent transition)
Renamed Event.stop => Event.cancel
Removed v--modal-background-click element
Removed v--modal default class
Removed "delay" property - component is relying on modal & overlay transition durations
Added naive implementation of focus trap
Added source-maps
Added hideAll for dynamic modals
Fix: dialogs not working when componentName is changed
Fix: ActiveElement is blurred after before-open event is fired (it is possible to cache document.activeElement now)

Simple to use, highly customizable, mobile-friendly Vue.js 2.0+ modal with SSR support. http://vue-js-modal.yev.io/

Install

npm install vue-js-modal --save

How to use

Include plugin in your main.js file.

import VModal from 'vue-js-modal'

Vue.use(VModal)

By default, the plugin will use "modal" name for the component.

If you need to change it, you can do so by providing "componentName" param.

Example:

Vue.use(VModal, { componentName: "foo-modal" })

...

<foo-modal name="bar"></foo-modal>

Create modal:

hello, world!

</modal>

Call it from anywhere in the app:

methods: {

show () {

this.$modal.show('hello-world');

hide () {

this.$modal.hide('hello-world');

}

You can easily send data into the modal:

this.$modal.show('hello-world', { foo: 'bar' })

And receive it in beforeOpen event handler:

methods: {

beforeOpen (event) {

console.log(event.params.foo);

}

If you use Bower package manager - you will have to initialize library differently:

Vue.use(window["vue-js-modal"].default);

Dialog

It is a simplified version of the modal, which has most parameters set by default and is pretty useful for quick prototyping, showing alerts or creating mobile-like modals.

To start using <v-dialog /> you must set dialog: true in plugin configuration:

Vue.use(VModal, { dialog: true })

And include it in your project:

<v-dialog />

Call it (all params except of “text” are optional):

this.$modal.show('dialog', {

title: 'Alert!',

text: 'You are too awesome',

buttons: [

{

title: 'Deal with it',

handler: () => { alert('Woot!') }

{

title: '', // Button title

default: true, // Will be triggered by default if 'Enter' pressed.

handler: () => {} // Button click handler

{

title: 'Close'

}

]

})

Dynamic Modals

In order to instantiate modals at runtime (for lazy-loading or decluttering templates), it is possible to create modals dynamically.

To start using this feature you must set dynamic: true in plugin configuration:

Vue.use(VModal, { dynamic: true, dynamicDefaults: { clickToClose: false } })

And include the <modals-container /> component it in your project:

<modals-container />

Alternatively, the modals container can be automatically appended to the document body once the plugin is loaded using injectModalsContainer: true:

Vue.use(VModal, { dynamic: true, injectModalsContainer: true })

Call it (the first argument is the component definition, the second are component properties, the third modal parameters, and the fourth the modal event listeners):

this.$modal.show({

<div>

<h1>This is created inline</h1>

</div>

props: ['text']

}, {

text: 'This text is passed as a property'

}, {

height: 'auto'

}, {

'before-close': (event) => { console.log('this will be called before the modal closes'); }

})

It can also be used with .vue files:

import MyComponent from './MyComponent.vue'

this.$modal.show(MyComponent, {

text: 'This text is passed as a property'

}, {

draggable: true

})

Other than defining the name modal parameter, it's also possible to close dynamic modals emitting a 'close' event:

this.$modal.show({

<div>

<p>Close using this button:</p>

<button @click="$emit('close')">Close</button>

</div>

})

If using the injectModalsContainer flag, the first mounted Vue instance without parents will be treated as the application root. This is only important to keep in mind if more than one root Vue instance is being used, which is unlikely. But if that's the case, the root to use can be indicated with the root parameter when invoking dynamic modals or modifying this plugin's rootInstance attribute:

import App from './App.vue'

import VModal from 'vue-js-modal'

const app1 = new Vue({

el: '#app-1',

render: h => h(App)

})

const app2 = new Vue({

el: '#app-2',

render: h => h(App)

})

VModal.rootInstance = app2

It is possible to set default property values for dynamic modals.

Example:

import VueJsModal from 'plugin'

Vue.use(VueJsModal, {

dynamic: true,

dynamicDefaults: {

foo: 'foo'

}

})

{

showDynamicRuntimeModal () {

this.$modal.show({

<p>Default Property: {{ foo }} - value is "foo"</p>

</div>

props: ['text', 'foo']

}, {

text: 'This text is passed as a property'

})

}

For more examples please take a look at vue-js-modal.yev.io.

Note: keep in mind that there are some limitations in using dynamic modals. If you need full functionality then use ordinary modal instead.

SSR

Include plugin in your nuxt.config.js file:

module.exports = {

plugins: ['~plugins/vue-js-modal']

}

And your plugins/vue-js-modal.js will look like:

import Vue from 'vue'

import VModal from 'vue-js-modal/dist/ssr.index'

Vue.use(VModal)

Extracted CSS

There is also an SSR build with CSS file extracted. Take a look in /dist folder.

Properties

Name	Required	Type	Default	Description
name	true	[String, Number]		Name of the modal
delay	false	Number	0	Delay between showing overlay and actual modal box
resizable	false	Boolean	false	If true allows resizing the modal window, keeping it in the center of the screen.
adaptive	false	Boolean	false	If true, modal box will try to adapt to the window size
draggable	false	[Boolean, String]	false	If true, modal box will be draggable. If string, a selector to use as a handle for dragging
scrollable	false	Boolean	false	If `height` property is `auto` and the modal height exceeds window height - you will be able to scroll modal
reset	false	Boolean	false	Resets position and size before showing modal
focus-trap	false	Boolean	false	Enable focus trap (plugin uses naive implementation of the focus trap)
clickToClose	false	Boolean	true	If set to `false`, it will not be possible to close modal by clicking on the background
transition	false	String		Transition name
overlayTransition	false	String	'overlay-fade'	Transition name for the background overlay
classes	false	[String, Array]	''	Classes that will be applied to the modal box
styles	false	[String, Array, Object]		Style that will be applied to the modal box (currently only supports strings)
width	false	[String, Number]	600	Width in pixels or percents (e.g. 50 or "50px", "50%")
height	false	[String, Number]	300	Height in pixels or percents (e.g. 50 or "50px", "50%") or `"auto"`
minWidth	false	Number (px)	0	The minimum width to which modal can be resized
minHeight	false	Number (px)	0	The minimum height to which modal can be resized
maxWidth	false	Number (px)	Infinity	The maximum width of the modal (if the value is greater than window width, window width will be used instead
maxHeight	false	Number (px)	Infinity	The maximum height of the modal (if the value is greater than window height, window height will be used instead
pivotX	false	Number (0 - 1.0)	0.5	Horizontal position in %, default is 0.5 (meaning that modal box will be in the middle (50% from left) of the window
pivotY	false	Number (0 - 1.0)	0.5	Vertical position in %, default is 0.5 (meaning that modal box will be in the middle (50% from top) of the window
root	false	Vue instance	null	Root instance to obtain modal container from. This property is only necessary when using dynamic modals with more than one root instance, which is uncommon

Events

Name	Description
before-open	Emits while modal is still invisible, but was added to the DOM
opened	Emits after modal became visible or started transition
before-close	Emits before modal is going to be closed. Can be stopped from the event listener calling `event.cancel()` (example: you are creating a text editor, and want to stop closing and ask the user to correct mistakes if the text is not valid)
closed	Emits right before modal is destroyed

Example:

<modal name="example"

:width="300"

:height="300"

@before-open="beforeOpen"

@before-close="beforeClose">

</modal>

</template>

export default {

data () {

return {

time: 0,

duration: 5000

}

methods: {

beforeOpen (event) {

console.log(event)

// Set the opening time of the modal

this.time = Date.now()

beforeClose (event) {

console.log(event)

// If modal was open less then 5000 ms - prevent closing it

if (this.time + this.duration < Date.now()) {

event.cancel()

}

</script>

Example with a dynamic modal:

export default {

data () {

return {

time: 0,

duration: 5000

}

methods: {

openModal () {

this.$modal.show({

props: ['time']

}, {

time: this.time

}, {

width: 300,

height: 300

}, {

'before-open': this.beforeOpen,

'before-close': this.beforeClose

})

beforeOpen (event) {

console.log(event)

// Set the opening time of the modal

this.time = Date.now()

beforeClose (event) {

console.log(event)

// If modal was open less then 5000 ms - prevent closing it

if (this.time + this.duration < Date.now()) {

event.cancel()

}

</script>

This example initializes time variable every time the modal is being opened. And then forbids closing it for the next 5000 ms

Other

Height: "auto"

From v1.2.6 height can be set to "auto". If you want to be able to scroll modal in case it's height exceeds window height - you can set flag scrollable="true".

p.s. scrollable will only work with height="auto".

Example:

Auto height:

Scrollable content & auto height:

Close button

If you want to have a Close (x) button in the top-right corner, you can use "top-right" slot for it. There is deliberately no predefined Close button style - you will have to implement/use your own button.

Example:

❌

</button>

</div>

Hello, ☀️!

</modal>

</template>

Draggable handler

Draggable property can accept not only Boolean but also String parameters. With String value, you can specify a CSS selector to the element which will be a "handler" for dragging.

Example:

<div>

Hello, !

</div>

</modal>

Overlay background color

If you want to change overlay background color, you can easily do it using CSS.

For all modals:

.vm--overlay {

background: red;

}

For specific modal:

background: transparent;

}

Fullscreen

Dont forget about close button :)

</modal>

IE support

This plugin uses arrow functions, resize observer and other features of modern after-2008-financial-crisis world.

To be able to use this plugin in IE you need to make sure that you transpile the code preoperty. Please read this stackoverflow: https://stackoverflow.com/questions/56446904/transpiling-es6-for-ie11-with-babel
