Quickstart

Note: this quickstart requires webpack and NPM

First, get Simple Slider from NPM:

npm i --save a-simple-slider

Then import SimpleSlider from that package in your webpack'd file:

import {SimpleSlider} from "a-simple-slider";

Finally, make sure to somehow include the CSS/SASS file associated with this project.

And you're set to start using Simple Slider. See the Simple Setup instructions to setup your first slider!

Browser Support

Supports ~88.39% (source) of browsers; specifically supporting modern versions of all browsers but Internet Explorer, which this plugin fully isn't supported in, primarily due to the use of the Promise object.

Integration/Installation

SimpleSlider.js has both CSS and JS dependencies, which you can integrate into your build/site below.

Note: All paths specified below are project-relative to this project, and you may need to move those files to the right spot in your project.

Javascript

Either directly import the dist/js/simple-slider.min.js file into your page, or integrate src/SimpleSlider.js into your build process.

CSS

Either directly import the dist/css/SimpleSlider.css into your stylesheet or page, or you can integrate the slider into your SASS build by importing the sass/SimpleSlider.scss into your build.

Examples

Below are a few examples. Expect more detailed examples/documentation in the Wiki and on the demo site.

Simple Setup

SimpleSlider.init({
    selector: "#my-slider"
});

or

SimpleSlider.init({
    element: document.getElementById("#my-slider")
});

Custom Delay Between Slides

SimpleSlider.init({
    selector: "#my-slider",
    delay: 10000 // in milliseconds
});

Config Options

The setup configuration object for a Simple Slider takes a number of options, which are documented below.

Name	Key	Type	Default	Required?	Description
Element	element	HTMLElement	null	Yes*	The HTMLElement object representing the slider itself. Required if the selector option isn't set
Selector	selector	String	null	Yes*	The CSS selector that selects the HTMLElement representing the slider itself. Required if the element option isn't set
Delay	delay	Integer	5000	No	The delay that the slider waits (in milliseconds) before switching to the next slide
Paused	paused	Boolean	False	No	Sets the paused state of the Slider. If true, the slider will not automatically switch between slides after a delay

SASS

You can, if you would like, include the SASS file located in sass/ into your project build. If so, the below default variables are available to override.

Move Speed

Variable Name: $simple-slider_move-speed
Default: 1000ms

This controls how fast the slider changes between slides. Can be any normal unit of time.

Events

The slider can emit events that will allow you to tie into what the slider is doing. Those are listed below.

To listen to a specific event, you can specify the event like so:

slider.addEventListener("eventName", function(eventName, data, slider) {
    // do something when the event is fired here
});

To listen to any event emitted by the slider, just set the eventName parameter to null or equivalent:

slider.addEventListener(null, function(eventName, data, slider) {
    // do something when any event is fired.
    // You can use the eventName parameter to figure out what event happened
});

Moving to Next Slide Event

Name: action.moving.next

Fired when the slider starts to move to the next slide in sequence.

Moving to the Previous Slide Event

Name: action.moving.previous

Fired when the slider starts to move to the previous slide in sequence.

Index Changed Event

Name: index.changed

Fired when the index of the active slide changes. Includes the index that the slider changed to.

Note: this is fired at the end of the sliding animation.
