Events.scrollEvent.register('begin', (to, element) => { console.log('begin', to, element); }); // Registering the 'end' event and logging it to the console when triggered. Events.scrollEvent.register('end', (to, element) => { console.log('end', to, element); }); // Updating scrollSpy when the component mounts. scrollSpy.update(); // Returning a cleanup function to remove the registered events when the component unmounts. return () => { Events.scrollEvent.remove('begin'); Events.scrollEvent.remove('end'); }; }, []); // Defining functions to perform different types of scrolling. const scrollToTop = () => { scroll.scrollToTop(); }; const scrollToBottom = () => { scroll.scrollToBottom(); }; const scrollTo = () => { scroll.scrollTo(100); // Scrolling to 100px from the top of the page. }; const scrollMore = () => { scroll.scrollMore(100); // Scrolling an additional 100px from the current scroll position. }; // Function to handle the activation of a link. const handleSetActive = (to) => { console.log(to); }; // Rendering the component's JSX. return (

{/* Link component to scroll to "test1" element with specified properties */} Test 1 {/* Other Link and Button components for navigation, each with their unique properties and targets */} {/* ... */} {/* Element components that act as scroll targets */} test 1 test 2

test 6 (anchor)

{/* Links to elements inside a specific container */} Go to first element inside container Go to second element inside container {/* Container with elements inside */}

first element inside container second element inside container

{/* Anchors to trigger scroll actions */} To the top!
To the bottom!
Scroll to 100px from the top
Scroll 100px more from the current position!

); }; export default Section; ``` ### Props/Options

activeClass	class applied when element is reached
activeStyle	style applied when element is reached
to	Target to scroll to
containerId	Container to listen for scroll events and to perform scrolling in
spy	Make Link selected when scroll is at its targets position
hashSpy	Update hash based on spy, containerId has to be set to scroll a specific element
smooth	Animate the scrolling
offset	Scroll additional px ( like padding )
duration	time of the scroll animation - can be a number or a function (`function (scrollDistanceInPx) { return duration; }`), that allows more granular control at run-time
delay	Wait x milliseconds before scroll
isDynamic	In case the distance has to be recalculated - if you have content that expands etc.
onSetActive	Invoke whenever link is being set to active
onSetInactive	Invoke whenever link is lose the active status
ignoreCancelEvents	Ignores events which cancel animated scrolling
horizontal	Whether to scroll vertically (`false`) or horizontally (`true`) - default: `false`
spyThrottle	Time of the spy throttle - can be a number

### Full example ```js Your name ``` ### Scroll Methods > Scroll To Top ```js import { animateScroll } from 'react-scroll'; const options = { // your options here, for example: duration: 500, smooth: true, }; animateScroll.scrollToTop(options); ``` > Scroll To Bottom ```js import { animateScroll } from 'react-scroll'; const options = { // Your options here, for example: duration: 500, smooth: true, }; animateScroll.scrollToBottom(options); ``` > Scroll To (position) ```js import { animateScroll } from 'react-scroll'; const options = { // Your options here, for example: duration: 500, smooth: true, }; // Scroll to 100 pixels from the top of the page animateScroll.scrollTo(100, options); ``` > Scroll To (Element) animateScroll.scrollTo(positionInPixels, props = {}); ```js import { Element, scroller } from 'react-scroll'; // Somewhere else, even another file scroller.scrollTo('myScrollToElement', { duration: 1500, delay: 100, smooth: true, containerId: 'ContainerElementID', offset: 50, // Scrolls to element + 50 pixels down the page // ... other options }); ``` > Scroll More (px) ```js import { animateScroll } from 'react-scroll'; const options = { // Your options here, for example: duration: 500, smooth: true, }; // Scroll an additional 10 pixels down from the current scroll position animateScroll.scrollMore(10, options); ``` ### Scroll events > begin - start of the scrolling ```js import { Events } from 'react-scroll'; Events.scrollEvent.register('begin', function(to, element) { console.log('begin', to, element); }); ``` > end - end of the scrolling/animation ```js import { Events } from 'react-scroll'; Events.scrollEvent.register('end', function(to, element) { console.log('end', to, element); }); ``` > Remove events ```js import { Events } from 'react-scroll'; Events.scrollEvent.remove('begin'); Events.scrollEvent.remove('end'); ``` #### Create your own Link/Element > Simply just pass your component to one of the high order components (Element/Scroll) ```js import React from 'react'; import { ScrollElement, ScrollLink } from 'react-scroll'; const Element = (props) => { return (

{ props.parentBindings.domNode = el; }}> {props.children}

); }; export const ScrollableElement = ScrollElement(Element); const Link = (props) => { return ( {props.children} ); }; export const ScrollableLink = ScrollLink(Link); ``` ### Scroll Animations > Add a custom easing animation to the smooth option. This prop will accept a Boolean if you want the default, or any of the animations listed below ```js import { scroller } from 'react-scroll'; scroller.scrollTo('myScrollToElement', { duration: 1500, delay: 100, smooth: 'easeInOutQuint', containerId: 'ContainerElementID', // ... other options }); ``` > List of currently available animations: ``` linear - no easing, no acceleration. easeInQuad - accelerating from zero velocity. easeOutQuad - decelerating to zero velocity. easeInOutQuad - acceleration until halfway, then deceleration. easeInCubic - accelerating from zero velocity. easeOutCubic - decelerating to zero velocity. easeInOutCubic - acceleration until halfway, then deceleration. easeInQuart - accelerating from zero velocity. easeOutQuart - decelerating to zero velocity. easeInOutQuart - acceleration until halfway, then deceleration. easeInQuint - accelerating from zero velocity. easeOutQuint - decelerating to zero velocity. easeInOutQuint - acceleration until halfway, then deceleration. ``` A good visual reference can be found at [easings.net](http://easings.net/) #### Changelog - [See the CHANGELOG](./CHANGELOG.md)
