Getting Started

Installing

• For the pros:

  • npm install vanilla-picker --save
  • import Picker from 'vanilla-picker';

• For the rest of us:

<script src="https://unpkg.com/vanilla-picker@2"></script>

Note:

The script adds a <style> element to the page, with all the needed CSS. If your site's Content Security Policy doesn't allow that, use the CSP build with a separate CSS file instead:

import Picker from 'vanilla-picker/csp';
import 'vanilla-picker/dist/vanilla-picker.csp.css';

..or

<script src="vanilla-picker.csp.min.js"></script>
<link  href="vanilla-picker.csp.css" rel="stylesheet">

Usage

<div id="parent">Click me</div>

<script>

    /*
        Create a new Picker instance and set the parent element.
        By default, the color picker is a popup which appears when you click the parent.
    */
    var parent = document.querySelector('#parent');
    var picker = new Picker(parent);

    /*
        You can do what you want with the chosen color using two callbacks: onChange and onDone.
    */
    picker.onChange = function(color) {
        parent.style.background = color.rgbaString;
    };

    /* onDone is similar to onChange, but only called when you click 'Ok' */

</script>

Accessibility

The color picker is built to support basic keyboard navigation and use with screen readers. I would be very interested in feedback on improvements that could be done here!
