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/colr_pickr@2.0.0/build/colr_pickr.min.js"
  ></script>

  <link
      rel="stylesheet"
      type="text/css"
      href="https://cdn.jsdelivr.net/npm/@r-tek/colr_pickr@2.0.0/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>
