### Install

```bash
npm install vue-js-modal --save
```

### How to use

Include plugin in your `main.js` file.

```javascript
import VModal from 'vue-js-modal'

Vue.use(VModal)

/*
By default 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:

```vue
<modal name="hello-world">
  hello, world!
</modal>
```
Call it from anywhere in the app:

```javascript
methods: {
  show () {
    this.$modal.show('hello-world');
  },
  hide () {
    this.$modal.hide('hello-world');
  }
}
```
---

You can easily send data into the modal:

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

And receive it in `beforeOpen` event handler:

```vue
<modal name="hello-world" @before-open="beforeOpen"/>
```
```javascript
methods: {
  beforeOpen (event) {
    console.log(event.params.foo);
  }
}
```

### Dialog

In version `1.2.8`, the `<v-dialog/>` component was added.

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:

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

And include it in your project:

```vue
<v-dialog/>
```

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

```javascript
this.$modal.show('dialog', {
  title: 'Alert!',
  text: 'You are too awesome',
  buttons: [
    { title: 'Deal with it', handler: () => { alert('Woot!') },
    { title: 'Close' }
 ]
})
```

For more examples please take a look at [vue-js-modal.yev.io](http://vue-js-modal.yev.io).

### SSR

Include plugin in your `nuxt.config.js` file:

```javascript
module.exports = {
  plugins: ['~plugins/vue-js-modal']
}
```

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

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

Vue.use(VModal)
```

For full demo please look at `demo/server_side_rendering`

| resizable | false | Boolean          | false       | If true, allows to resize 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. |
| 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 |

| height    | false | [String, Number] | 300         | Height in pixels or percents (e.g. 50 or "50px", "50%") or `"auto"` |

| 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 top) 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 left) of the window |

### 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.stop()` (example: you are creating a text editor, and want to stop closisng and ask user to correct mistakes if text is not valid)
| closed       | Emits right before modal is destoyed |

Example:
```vue
<template>
  <modal name="example"
         :width="300"
         :height="300"
         @before-open="beforeOpen"
         @before-close="beforeClose">
    <b>{{time}}</b>
  </modal>
</template>
<script>
export default {
  name: 'ExampleModal',
  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.stop()
      }
    }
  }
}
</script>
```

This example, initializes `time` variable every time the modal is being opened.
And then forbits 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: 

```vue
<modal name="foo" height="auto" :scrollable="true">...</modal>
```

Auto height:

</p>


#### 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:
```vue
<template>
  <modal name="foo">

    <div slot="top-right">
      <button @click="$modal.hide('foo')">
        ❌
      </button>
    </div>

    Hello, ☀️!

  </modal>
</template>
```


#### Draggable handler

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

Example:

```vue
<modal name="bar" draggable=".window-header">
  <div class="window-header">DRAG ME HERE</div>
  <div>
     Hello, 🌎!
  </div>
</modal>
```

#### Background color

If you want to change overflow background color, you can easily do it using css.

For all modals: 

```css
.v--modal-overlay {
  background: red;
}
```

For specific modal:

```css
.v--modal-overlay[data-modal="my_modal_name"] {
  background: cyan;
}
```

#### Fullscreen

```vue
<modal name="fs" :adaptive="true" width="100%" height="100%">
Dont forget about close button :)
</modal>
```
