Examples:

Getting Started:

Installation
  • Install with NPM:

    $ npm i @r-tek/colr_pickr

    If you are using a bundler like Webpack, you can import the module:

    // ES6
    import pickr from '@r-tek/colr_pickr';
    
    // OR
    
    // CommonJs
    const pickr = require('@r-tek/colr_pickr');

    For now, you'll need to bring in the CSS file through one of the methods below.


  • Using the CDN via jsDelivr:
    <script
    	type="text/javascript"
    	src="https://cdn.jsdelivr.net/npm/@r-tek/[email protected]/build/colr_pickr.min.js"
    ></script>
    <link
    	rel="stylesheet"
    	type="text/css"
    	href="https://cdn.jsdelivr.net/npm/@r-tek/[email protected]/build/colr_pickr.min.css"
    />

  • Alternatively, you could clone/download the repository. Under the /build directory, include the colr_pickr_min.js and the colr_pickr_min.css in your project.
Usage
<!-- Add a button to your HTML document and give it any ID -->

<button id="my_picker"></button>

<!-- The rest is in your JavaScript file, or in this case a script tag -->

<script type="text/javascript">
	/**
	 * Create a new ColorPicker instance, which takes 2 parameters
	 *
	 * Parameter 1 [HTMLElement]: the button you want to launch the editor
	 * Parameter 2 [String] (Optional): A color
	 */

	const button = document.getElementById('my_picker');
	let picker = new ColorPicker(button, '#ff0000');

	/**
	 * What do you want to do after you have chosen the color?
	 *
	 * You can specify this in an EventListener, assigned to your button
	 */

	button.addEventListener('colorChange', function (event) {
		// This will give you the color you selected
		const color = event.detail.color.hexa;

		// Code to do what you want with that color...
	});

	/**
	 * You can also change the color yourself via JavaScript
	 *
	 * If you want to change the selected color for an instance without using the picker
	 * You can call the following function
	 *
	 * Parameter 1 [String]: Color
	 * Parameter 2 [HTMLElement]: The button that holds the instance / picker launch button
	 */

	colorPickerComp.colorChange('#ff00ff', button);
</script>
