DEMO

View demo on jsFiddle

What is this?

A plugin to open stocked modals windows, event based, with just one component in your DOM.

What do you mean with "just one component"?

e.g. if you want to have 3 modals, you don't need to add the component 3 times, just one (preferably in the root of your app) and open as many modals as you want by using an Event Bus

Install

Install with npm:

npm install --save vuedals

Example

import Vue from 'vue';
import {default as Vuedals, Component as Vuedal, Bus as VuedalsBus} from 'vuedals';

Vue.use(Vuedals);

var myComp = Vue.extend({
    template: `<div>
            <h1>Hello World!</h1>
            <button @click="showIt()">Show me the money</button>
        </div>`,

    methods: {
        showIt() {
            VuedalsBus.$emit('new', {
                name: 'showing-the-money',

                component: {
                    name: 'the-money',

                    template: `
                        <div>
                            <h1>THE MONEY!</h1>
                            <p>Money, money, money, moooneeyyy $ $ $ $</p>
                        </div>
                    `
                }
            });
        }
    }
});

var vm = new Vue({
    el: '#app',

    components: {
        myComp,
        Vuedal
    },

    template: `<div>
        <my-comp></my-comp>

        <vuedal></vuedal>
    </div>`
});

Usage

Opening a new modal window

You can emit an event in your component:

this.$emit('vuedals:new', { option });

or a method:

this.$vuedals.new({ options });

or the Vuedals Event Bus:

import {Bus as Vuedals} from 'vuedals';

...

methods: {
    openNewModal() {
        Vuedals.$emit('new', { options });
    }
}

Closing a modal

You can emit an event in your component:

this.$emit('vuedals:close'[, data]);

a method:

this.$vuedals.close([data]);

or the Vuedals Event Bus:

import {Bus as Vuedals} from 'vuedals';

...

methods: {
    openNewModal() {
        Vuedals.$emit('close'[, data]);
    }
}

Closing an especific modal

If you need to close a specific modal index, you can pass it as an $index property of the data.

this.$vuedals.close({
    $index: 3
})

$index can be an integer or a function. In case $index is a function, the additional data and all the vuedals that is currently present is index(data, this.vuedals) passed as argument so that you can determine the index of the vudedal to close and return the index of it

this.$vuedals.close({
    $index(data, vuedals) {
        // this will always close the latest modal
        return vuedals.length - 1;
    }
})

Events

Depending if you're creating the modal from the component or from the Vuedals Event Bus, these are the events (component / bus):

vuedals:new / new

Open a new modal window, with the given options

vuedals:close / close

Close the most recently opened modal window, if data is given, will pass it to the onClose option.

vuedals:opened / opened

1. The index of the recently opened modal
2. The options passed to that modal instance

vuedals:closed / closed

When a modal was closed. Returns an object with:

1. The index of the closed modal
2. The options passed to that modal instance
3. The data given when close was called

vuedals:destroyed / destroyed

1. The index of the closed modal
2. The options passed to that modal instance
3. The data given when close was called

onClose

Callback function to call when the modal is closed. Any given data is passed as a parameter for that callback. Example:

this.$vuedals.open({
    name: 'test-component',

    // Pass these props to the component
    props: {
        firstname: 'John',
        lastname: 'Doe'
    },

    component: {
        name: 'show-john-doe',

        // Pass these props to the component
        props: ['firstname', 'lastname'],

        template: `
            <div>
                Hi {{ firstname }} {{ lastname }}
            </div>
        `
    },

    onClose(data) {
        console.log('Data received from the vuedal instance': data);
    }
});

onDismiss

Callback function to call when the modal is closed.

Please notice that even close and dismiss both close the active modal instance (closes the modal) only the close event accepts data argument that can be passed to the callback, while dismiss just send the modal to close.

The callback may prevent the modal closing by returning false.

Example:

this.$vuedals.open({
    name: 'test-component',

    // Pass these props to the component
    props: {
        firstname: 'John',
        lastname: 'Doe'
    },

    component: {
        name: 'show-john-doe',

        // expect these props
        props: ['firstname', 'lastname'],

        template: `
            <div>
                Hi {{ firstname }} {{ lastname }}
            </div>
        `
    },

    onDismiss() {
        console.log('The user dismissed the modal');
    }
});
