JSPM – react-scroll@1.4.3

Package Exports

react-scroll
react-scroll/lib/mixins/animate-scroll
react-scroll/lib/mixins/scroller

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-scroll) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

var React   = require('react');
var Scroll  = require('react-scroll');

var Link       = Scroll.Link;
var Element    = Scroll.Element;
var Events     = Scroll.Events;
var scroll     = Scroll.animateScroll;
var scrollSpy  = Scroll.scrollSpy;


var Section = React.createClass({

    });

    Events.scrollEvent.register('end', function(to, element) {
      console.log("end", arguments);
    });

    scrollSpy.update();

  },
  componentWillUnmount: function() {

        <Link to="firstInsideContainer" containerId="containerElement">
          Go to first element inside container
        </Link>

        <Link to="secondInsideContainer" containerId="containerElement">
          Go to second element inside container
        </Link>
        <div className="element" id="containerElement">
          <Element name="firstInsideContainer">
            first element inside container
          </Element>

          <Element name="secondInsideContainer">
            second element inside container

        </div>

        <a onClick={this.scrollToTop}>To the top!</a>
        <br/>
        <a onClick={this.scrollToBottom}>To the bottom!</a>
        <br/>
        <a onClick={this.scrollTo}>Scroll to 100px from the top</a>

spy - make Link selected when scroll is at it's targets position

smooth - animate the scrolling

offset - scroll additional px ( like padding )

duration - time of the scroll animation

Scroll Methods

Scroll To Top

var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollToTop(options);

Scroll To Bottom

var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollToBottom(options);

Scroll To (position)

var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollTo(100, options);

Scroll To (Element)

animateScroll.scrollTo(positionInPixels, props = {});

var Scroll = require('react-scroll');
var Element = Scroll.Element;
var scroller = Scroll.scroller;

<Element name="myScrollToElement"></Element>

// Somewhere else, even another file
scroller.scrollTo('myScrollToElement', {
  duration: 1500,
  delay: 100,
  smooth: true,
})

Scroll More (px)

var Scroll = require('react-scroll');
var scroll = Scroll.animateScroll;

scroll.scrollMore(10, options);

Scroll events

begin - start of the scrolling

var Scroll = require('react-scroll');
var Events = Scroll.Events;

Events.scrollEvent.register('begin', function(to, element) {
  console.log("begin", to, element);
});

end - end of the scrolling/animation

Events.scrollEvent.register('end', function(to, element) {
  console.log("end", to, element);
});

Remove events

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)

var React   = require('react');
var Scroll  = require('react-scroll');
var Helpers = Scroll.Helpers;

var Element = React.createClass({
  render: function () {
    return (
      <div {...this.props}>
        {this.props.children}
      </div>
    );
  }
});

module.exports = Helpers.Element(Element);

var Link = React.createClass({
  render: function () {
    return (
      <a {...this.props}>
        {this.props.children}
      </a>
    );
  }
});

module.exports = Helpers.Scroll(Link);
