## Install
### npm
```
npm install pageable --save
```
---
### Browser
Grab the file from one of the CDNs and include it in your page:
```
https://unpkg.com/pageable@latest/dist/pageable.min.js
```
You can replace `latest` with the required release number if needed.
You can also include the optional stylesheet that applies styling to the nav pips and buttons:
```
https://unpkg.com/pageable@latest/dist/pageable.min.css
```
---
## Set up
Define a container element that has at least one descendant element with the `data-anchor` attribute.
### HTML
```html
....
```
Instantiate Pageable and pass a reference to the container in the constructor:
### JS
```javascript
new Pageable("#container");
```
The HTML will be transformed in the following way:
```html
...
```
If you don't set the `[data-anchor]` attribute then you must set the anchors with the [`anchors`](#anchors-1) option.
If `pips` are enabled, their HTML will be appended to the `.pg-wrapper` element after the `.pg-container` element.
The defined anchors will be 'slugified' and used as the page's `id` - e.g. `My Page 1` will be converted to `my-page-1`
Take care not to have another element with a duplicate `id`
---
You can pass an object as the second paramater to customise the instance:
### JS
```javascript
new Pageable("#container", {
childSelector: "[data-anchor]" // CSS3 selector string for the pages
anchors: [], // define the page anchors
pips: true, // display the pips
animation: 300, // the duration in ms of the scroll animation
delay: 0, // the delay in ms before the scroll animation starts
throttle: 50, // the interval in ms that the resize callback is fired
orientation: "vertical", // or horizontal
swipeThreshold: 50, // swipe / mouse drag distance (px) before firing the page change event
freeScroll: false, // allow manual scrolling when dragging instead of automatically moving to next page
navPrevEl: false, // define an element to use to scroll to the previous page (CSS3 selector string or Element reference)
navNextEl: false, // define an element to use to scroll to the next page (CSS3 selector string or Element reference)
infinite: false, // enable infinite scrolling (from 0.4.0)
slideshow: { // enable slideshow that cycles through your pages automatically (from 0.4.0)
interval: 3000, // time in ms between page change,
delay: 0 // delay in ms after the interval has ended and before changing page
},
events: {
wheel: true, // enable / disable mousewheel scrolling
mouse: true, // enable / disable mouse drag scrolling
touch: true, // enable / disable touch / swipe scrolling
keydown: true, // enable / disable keyboard navigation
},
easing: function(currentTime, startPos, endPos, interval) {
// the easing function used for the scroll animation
return -endPos * (currentTime /= interval) * (currentTime - 2) + startPos;
},
onInit: function() {
// do something when the instance is ready
},
onUpdate: function() {
// do something when the instance updates
},
onBeforeStart: function() {
// do something before scrolling begins
},
onStart: function() {
// do something when scrolling begins
},
onScroll: function() {
// do something during scroll
},
onFinish: function() {
// do something when scrolling ends
},
});
```

### Anchors
Any anchor on your page that has a hash that matches the ones in the current `Pageable` instance will trigger scrolling. This allows you to add navigation links without needing to define event listeners or callbacks to get them to trigger a scroll.
---
## API Reference
---
## Options
### `childSelector`
###### type: `Boolean`
###### default: `true`
A CSS3 selector string for selecting the nodes to be used as pages
---
### `anchors`
###### type: `Array`
###### default: `undefined`
An array of strings to use as the page anchors. Make sure the number of anchors used is equal to the number of pages.
---
### `pips`
###### type: `Boolean`
###### default: `true`
Displays the navigation pips.
---
### `animation`
###### type: `Number`

**NOTE: This option was known as `interval` in versions prior to `v0.5.0`**
---
### `delay`
###### type: `Number`
###### default: `0`
Sets the delay in `ms` before the scroll animation starts.
---
### `swipeThreshold`
###### type: `Number`
###### default: `50`
Sets the swipe / mouse drag distance in `px` before firing the page change event. If drag / swipe distance is below this threshold then scrolling will not activate.
---
### `freeScroll`
###### type: `Boolean`
###### default: `false`
Sets the ability to drag / scroll freely instead of snapping to the next page.
---
### `infinite`
###### type: `Boolean`
###### default: `false`
Allow seamless continuous scrolling.
---
### `orientation`
###### type: `String`
###### default: `'vertical'`
Sets the orientation of the instance. Either `'vertical'` or `'horizontal'`.
---
### `throttle`
###### type: `Number`
###### default: `50`
Sets the interval in `ms` that the resize callback is fired.
---
### `navPrevEl`

Define an element to use to scroll to the previous page. A valid CSS3 selector string or Element reference.
---
### `navNextEl`
###### type: `String|HTMLElement`
###### default: `false`
Define an element to use to scroll to the next page. A valid CSS3 selector string or Element reference.
---
### `slideshow`
###### type: `Object`
###### default: `false`
Enables the slideshow function that cycles through your pages automatically.
The object has two properties to further customise the slidewhow:
* `interval` - length of time in `ms` to display each page.
* `delay` - delay in `ms` after the interval has ended and before changing page.
---
### `events`
###### type: `Object`
Define the allowed events.
* `wheel` - enable / disable mousewheel scrolling
* `mouse` - enable / disable mouse drag scrolling
* `touch` - enable / disable touch / swipe scrolling
* `keydown` - enable / disable keyboard navigation
All properties are set to `true` by default.
---
### `easing`
###### type: `Function`
Define the easing function used for the scroll animation.
The function takes four `arguments`:
```javascript
function(currentTime, startPos, endPos, interval) {
// the default easing function
return -endPos * (currentTime /= interval) * (currentTime - 2) + startPos;
}
```
* `currentTime` - The current time in `ms`
* `startPos` - The start position in `px`
* `endPos` - The end position in `px`
* `interval` - The duration of the animation in `ms`
---
### `onInit`
###### type: `Function`
###### default: `noop`
Define a callback to be called when the instance is fully rendered and ready for use.
The function takes a single argument that returns the data object (See [Custom Events](#custom-events))
```javascript
new Pageable("#container", {
onInit: function(data) {
// data.index, data.scrolled, data.max
}
});
```
---
### `onUpdate`

###### default: `noop`
Define a callback to be called before scrolling begins.
The function takes a single argument that returns the data object (See [Custom Events](#custom-events))
---
### `onStart`
###### type: `Function`
###### default: `noop`
Define a callback to be called when scrolling begins.
The function takes a single argument that returns the data object (See [Custom Events](#custom-events))
---
### `onScroll`

###### default: `noop`
Define a callback to be called when scrolling finishes.
The function takes a single argument that returns the data object (See [Custom Events](#custom-events))
---
## Methods
### `destroy()`
Destroy the instance.
This will remove all event listeners and return the DOM to it's initial state.
```javascript
pageable.destroy();
```
---
### `init()`
Initialise the instance after destroying.
```javascript
pageable.init();
```
---
### `next()`
Scroll to next page.
```javascript
pageable.next();
```
---
### `prev()`
Scroll to previous page.
```javascript
pageable.prev();
```
---
### `scrollToPage([page])`
Scroll to defined page number.
```javascript
// scroll to page 3
pageable.scrollToPage(3);
```
---
### `scrollToAnchor([anchor])`
Scroll to defined anchor.
```javascript
pageable.scrollToAnchor("#myanchor");
```
---
### `orientate([orientation])`
Orientate the instance to either vertical or horizontal.
```javascript
pageable.orientate("horizontal");
// or
pageable.orientate("vertical");
```
---
### `slideshow()`
Returns an instance of the slideshow. This requires the `slideshow` option to be set to `true` (`v0.4.0` and above).
The sideshow instance has two methods:
* `start()` - starts / resumes the slideshow
* `stop()` - stops / pauses the slideshow
```javascript
// stop / pause slideshow
pageable.slideshow().stop();
// start / resume slideshow
pageable.slideshow().start();
```
---
### `on([event, [callback]])`
Add custom event listener. See [Custom Events](#custom-events)
---
### `off([event, [callback]])`
remove custom event listener. See [Custom Events](#custom-events)
---
## Custom Events
You can listen to Pageable's custom events with the `on(type, callback)` method.
The callback has one argument which returns the data object:
```javascript
{
index: // the current page index
scrolled: // the current scroll offset
max: // the maximum scroll amount possible
percent: // the scroll position as a percentage of the maximum scroll (v0.6.7 and above)
}
```
The `percent` property can be helpful when adding progress indicators (see [Adding Progress Bars](https://mobius1.github.io/Pageable/progress.html)).
### Examples
```javascript
const pages = new Pageable("#container");
pages.on("init", data => {
// do something when the instance is ready
});
pages.on("update", data => {
// do something when the instance is updated
// this event also fires when the screen size changes
});
pages.on("scroll.before", data => {
// do something before scrolling starts
// this event will fire when the defined delay begins
// e.g. if the delay is set to 400, this event will
// fire 400ms BEFORE the "scroll.start" event fires
});
pages.on("scroll.start", data => {
// do something when scrolling starts
// this event will fire when the defined delay ends
// e.g. if the delay is set to 400, this event will
// fire 400ms AFTER the "scroll.before" event fires
});
pages.on("scroll", data => {
// do something during scroll
});
pages.on("scroll.end", data => {
// do something when scrolling ends
});
```
