ezscroll

A useful tool that helps you to scroll in the browser window with animation. Time to give up window.scrollTo!

Installation

Via npm.

$ npm install ezscroll --save

Via yarn.

$ yarn add ezscroll

Basic Usage

Window scroll

You can simply replace all of your window.scrollTo with ezscroll.

import { scrollTo } from 'ezscroll';

// Same usage as window.scrollTo.
// But will scroll with animation.
scrollTo(0, 0);

Element scroll

You can also scroll inside your element.

import { elScrollTo } from 'ezscroll';

// `element` should be a container element.
elScrollTo(element, 0, 0);

Useful functions

For window scroll

We provide some useful functions which we think are in common use.

import { scrollToTop, scrollToLeft, scrollToRight, scrollToBottom } from 'ezscroll';

// Scroll to the top of the window.
scrollToTop();

// Scroll to the left of the window.
scrollToLeft();

// Scroll to the right of the window.
scrollToRight();

// Scroll to the bottom of the window.
scrollToBottom();

Or you may want some accurate control on one axis.

import { scrollXTo, scrollYTo } from 'ezscroll';

// Scroll to 10 on x axis.
scrollXTo(10);

// Scroll to 50 on y axis.
scrollYTo(50);

All functions above support customize duration and easing functions. For more details please refer to Full API.

import { scrollToTop, scrollXTo } from 'ezscroll';

scrollToTop(duration, easing, callback);
scrollXTo(x, duration, easing, callback);

For element scroll

Similar as above.

import {
  elScrollToTop,
  elScrollToLeft,
  elScrollToRight,
  elScrollToBottom,
  elScrollXTo,
  elScrollYTo,
} from 'ezscroll';

elScrollToTop(element, duration, easing, callback);
elScrollXTo(element, 0, duration, easing, callback);
