Build Setup

Plugin created with:

• Node.js >= 14.21.2
• npm 6.14.15
• jQuery 3.6.0

# Download repository:
$ git clone https://github.com/WhiteDevilMan/RangeSlider

# Go to the folder:
$ cd RangeSlider

# Install dependencies from package.json:
$ npm install (or 'npm i')

# Start server with hot reload
$ npm run dev

# Build project. Output will be at 'dist' folder
$ npm run build

# Build project with demo page. Output will be at 'dist' folder
$ npm run build-demo

# Deploy project to gh-pages (after "npm run build")
$ npm run deploy

# Run test
$ npm run test (or 'npm test')

# Lint Styles
$ npm run stylelint-fix

Plugin Configuration

First add jQuery CDN to your page, scripts and styles.

Example:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script defer src="range-slider-vendors.js"></script>
<script defer src="range-slider.js"></script>
<link href="range-slider.css" rel="stylesheet" />

Then you need to add <div> block with id on your page.

Example:

<div id="range-slider"></div>

And after it add RangeSlider plugin with settings to your.js file.

Example:

$('#range-slider').RangeSlider('init', {
  min: 0,
  max: 100,
  from: 20,
  to: 80,
  step: 1,
  range: true,
  scale: true,
  tooltips: true,
  vertical: false,
  confpanel: false,
  bar: true,
});

Also, you could use plugin from console in your browser with the same command

$('#range-slider').RangeSlider('init', {
  min: 0,
  max: 100,
  from: 20,
  to: 80,
  step: 1,
  range: true,
  scale: true,
  tooltips: true,
  vertical: false,
  confpanel: false,
  bar: true,
});

You may pass to slider settings that you need to update its settings

$('#range-slider').RangeSlider('update', {
  min: 20,
  max: 80,
  confpanel: true,
});

Slider Events

To subscribe to slider event you need to:

• Add Observer property to class properties and initialize it in the constructor

Example:

export default class View {
  changeSettingsObserver: AbstractObserver;

  constructor() {
    this.changeSettingsObserver = new Observer();
  }

• In the code where you want to subscribe on this observer add

yourObserver.addObserver(data? => { /* your code */ })

Example:

this.view.changeSettingsObserver.addObserver((settings) => {
  // Your code. Example:
  this.updateModelAndPanel(<IModelSettings>settings);
});

To unsubscribe from slider event you need to remove observer:

this.view.changeSettingsObserver.removeObserver((settings) => {
  // Your code. Example:
  this.updateModelAndPanel(<IModelSettings>settings);
});

Architecture

RangeSlider uses MVP (Model View Presenter) architecture.

Model - works with data, performs validations, calculations and manages business processes.

View - shows the user the interface and data from the model.

Presenter - serves as a layer between the model and the view.

Layers are unlinked from external dependencies using abstract classes. Data between layers is transmitted using the observer pattern.
