vue-scrollto

DEMO

Scrolling to elements was never this easy!

This is for vue 2.x

For vue 1.x use vue-scrollTo@1.0.1 (note the capital T) but keep in mind that the old version depends on jquery.

Under the hood

vue-scrollto uses window.requestAnimationFrame to perform the animations, thus giving the best performance.

Easing is done using bezier-easing - A well tested easing micro-library.

It even knows when the user interrupts, and doesn't force scrolling that would result in bad UX.

Installing

This package is available on npm.

If you used this package before, please ensure you are using the right one, since it has been renamed from `vue-scrollTo` to `vue-scrollto`

Using npm:

npm install --save vue-scrollto

Using yarn:

yarn add vue-scrollto

Directly include it in html:

<script src="https://unpkg.com/vue@2.2.4"></script>
<script src="https://unpkg.com/vue-scrollto"></script>

When including it in html, it will automatically call `Vue.use` and also set a `VueScrollTo` variable that you can use!

Usage

vue-scrollto can be used either as a vue directive, or programatically from your javascript.

As a vue directive

var Vue = require('vue');
var VueScrollTo = require('vue-scrollto');
 
Vue.use(VueScrollTo)
 
// You can also pass in the default options
Vue.use(VueScrollTo, {
     container: "body",
     duration: 500,
     easing: "ease",
     offset: 0,
     onDone: false,
     onCancel: false
 })

In case you are using the browser version (directly including the script on your page), you can set the defaults with

VueScrollTo.setDefaults({
    container: "body",
    duration: 500,
    easing: "ease",
    offset: 0,
    onDone: false,
    onCancel: false
})

<a href="#" v-scroll-to="'#element'">Scroll to #element</a>
 
<div id="element">
    Hi. I'm #element.
</div>

If you need to customize the scrolling options, you can pass in an object literal to the directive:

<a href="#" v-scroll-to="{
     el: '#element',
     container: '#container',
     duration: 500,
     easing: 'linear',
     offset: -200,
     onDone: onDone,
     onCancel: onCancel
 }">
    Scroll to #element
</a>

Check out the [Options Section](#options) for more details about the available options.

Programatically

var VueScrollTo = require('vue-scrollto');
 
var options = {
    container: '#container',
    easing: 'ease-in',
    offset: -60,
    onDone: function() {
      // scrolling is done
    },
    onCancel: function() {
      // scrolling has been interrupted
    }
}
 
VueScrollTo.scrollTo(element, duration, options)
 
// or alternatively inside your components you can use
this.$scrollTo(element, duration, options)

Options

el / element

The element you want to scroll to.

container

The container that has to be scrolled.

Default: body

duration

The duration (in milliseconds) of the scrolling animation.

Default: 500

easing

The easing to be used when animating. Read more in the Easing section.

Default: ease

offset

The offset that should be applied when scrolling.

Default: 0

onDone

A callback function that should be called when scrolling has ended.

Default: noop

onCancel

A callback function that should be called when scrolling has been aborted by the user (user scrolled, clicked etc.).

Default: noop

Easing

Easing is calculated using bezier-easing so you can pass your own values into options.easing in the form of an array with 4 values, or you can use any of the default easings by referencing their names as strings (ease, linear, ease-in, ease-out, ease-in-out).

vue-scrollto uses the following values for the default easings:

let easings = {
    'ease': [0.25, 0.1, 0.25, 1.0],
    'linear': [0.00, 0.0, 1.00, 1.0],
    'ease-in': [0.42, 0.0, 1.00, 1.0],
    'ease-out': [0.00, 0.0, 0.58, 1.0],
    'ease-in-out': [0.42, 0.0, 0.58, 1.0]
}
