Nano uses css-grid thus it won't work in older browsers.

Getting Started

Node

Note: The readme is always up-to-date with the latest commit. See Releases for installation instructions regarding to the latest version.

Install via npm:

$ npm install @simonwep/pickr

Install via yarn:

$ yarn add @simonwep/pickr

Include code and style:

// One of the following themes
import '@simonwep/pickr/dist/themes/classic.min.css';   // 'classic' theme
import '@simonwep/pickr/dist/themes/monolith.min.css';  // 'monolith' theme
import '@simonwep/pickr/dist/themes/nano.min.css';      // 'nano' theme

// Modern or es5 bundle
import Pickr from '@simonwep/pickr';
import Pickr from '@simonwep/pickr/dist/pickr.es5.min';

Browser

jsdelivr:

<!-- One of the following themes -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@simonwep/pickr/dist/themes/classic.min.css"/> <!-- 'classic' theme -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@simonwep/pickr/dist/themes/monolith.min.css"/> <!-- 'monolith' theme -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@simonwep/pickr/dist/themes/nano.min.css"/> <!-- 'nano' theme -->

<!-- Modern or es5 bundle -->
<script src="https://cdn.jsdelivr.net/npm/@simonwep/pickr/dist/pickr.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@simonwep/pickr/dist/pickr.es5.min.js"></script>

Be sure to load the pickr.min.js (or the es5 version) after pickr.min.css. Moreover the script tag doesn't work with the defer attribute.

Usage

// Simple example, see optional options for more configuration.
const pickr = Pickr.create({
    el: '.color-picker',
    theme: 'classic', // or 'monolith', or 'nano'

    swatches: [
        'rgba(244, 67, 54, 1)',
        'rgba(233, 30, 99, 0.95)',
        'rgba(156, 39, 176, 0.9)',
        'rgba(103, 58, 183, 0.85)',
        'rgba(63, 81, 181, 0.8)',
        'rgba(33, 150, 243, 0.75)',
        'rgba(3, 169, 244, 0.7)',
        'rgba(0, 188, 212, 0.7)',
        'rgba(0, 150, 136, 0.75)',
        'rgba(76, 175, 80, 0.8)',
        'rgba(139, 195, 74, 0.85)',
        'rgba(205, 220, 57, 0.9)',
        'rgba(255, 235, 59, 0.95)',
        'rgba(255, 193, 7, 1)'
    ],

    components: {

        // Main components
        preview: true,
        opacity: true,
        hue: true,

        // Input / output Options
        interaction: {
            hex: true,
            rgba: true,
            hsla: true,
            hsva: true,
            cmyk: true,
            input: true,
            clear: true,
            save: true
        }
    }
});

Events

Since version 0.4.x Pickr is event-driven. Use the on(event, cb) and off(event, cb) functions to bind / unbind eventlistener.

| Event | Description | Arguments | | -------------- | ----------- | --------- | | init | Initialization done - pickr can be used | PickrInstance | | hide | Pickr got closed | PickrInstance | | show | Pickr got opened | PickrInstance | | save | User clicked the save / clear button. Also fired on clear with null as color. | HSVaColorObject or null, PickrInstance | | clear | User cleared the color. | PickrInstance | | change | Color has changed (but not saved). Also fired on swatchselect | HSVaColorObject, PickrInstance | | changestop | User stopped to change the color | PickrInstance | | cancel | User clicked the cancel button (return to previous color). | PickrInstance | | swatchselect | User clicked one of the swatches | HSVaColorObject, PickrInstance |

Example:

pickr.on('init', instance => {
    console.log('init', instance);
}).on('hide', instance => {
    console.log('hide', instance);
}).on('show', (color, instance) => {
    console.log('show', color, instance);
}).on('save', (color, instance) => {
    console.log('save', color, instance);
}).on('clear', instance => {
    console.log('clear', instance);
}).on('change', (color, instance) => {
    console.log('change', color, instance);
}).on('changestop', instance => {
    console.log('changestop', instance);
}).on('cancel', instance => {
    console.log('cancel', instance);
}).on('swatchselect', (color, instance) => {
    console.log('swatchselect', color, instance);
});

            input: false, // Display input/output textbox which shows the selected color value.

       cancel: 'Cancel' // Default for cancel button

});

Selection through a Shadow-DOM

Example setup:

<div class="entry">
  #shadow-root
    <div class="innr">
       <div class="another">
         #shadow-root
           <div class="pickr"></div>
       </div>
    </div>
</div>

To select the .pickr element you can use the custom >> shadow-dom-selector in el:

el: '.entry >> .innr .another >> .pickr'

Every ShadowRoot of the query-result behind a >> gets used in the next query selection. An alternative would be to provide the target-element itself as el.

The HSVaColor object

As default color representation is hsva (hue, saturation, value and alpha) used, but you can also convert it to other formats as listed below.

• hsva.toHSVA() - Converts the object to a hsva array.
• hsva.toHSLA() - Converts the object to a hsla array.
• hsva.toRGBA() - Converts the object to a rgba array.
• hsva.toHEXA() - Converts the object to a hexa-decimal array.
• hsva.toCMYK() - Converts the object to a cmyk array.
• hsva.clone() - Clones the color object.

The toString() is overridden so you can get a color representation string.

hsva.toRGBA(); // Returns [r, g, b, a]
hsva.toRGBA().toString(); // Returns rgba(r, g, b, a) with highest precision
hsva.toRGBA().toString(3); // Returns rgba(r, g, b, a), rounded to the third decimal

Methods

• pickr.setHSVA(h:Number,s:Number,v:Number,a:Float, silent:Boolean) - Set an color, returns true if the color has been accepted.
• pickr.setColor(representation:String, silent:Boolean):Boolean - Parses a string which represents a color (e.g. #fff, rgb(10, 156, 23)) or name e.g. 'magenta', returns true if the color has been accepted. null will clear the color.

If silent is true (Default is false), the button won't change the current color.

• pickr.on(event:String, cb:Function):Pickr - Appends an event listener to the given corresponding event-name (see section Events).
• pickr.off(event:String, cb:Function):Pickr - Removes an event listener from the given corresponding event-name (see section Events).
• pickr.show():Pickr - Shows the color-picker.
• pickr.hide():Pickr - Hides the color-picker.
• pickr.disable():Pickr - Disables pickr and adds the disabled class to the button.
• pickr.enable():Pickr - Enables pickr and removes the disabled class from the button.
• pickr.isOpen():Pickr - Returns true if the color picker is currently open.
• pickr.getRoot():Object - Returns the dom-tree of pickr as tree-structure.
• pickr.getColor():HSVaColor - Returns the current HSVaColor object.
• pickr.getSelectedColor():HSVaColor - Returns the currently applied color.
• pickr.destroy() - Destroys all functionality.
• pickr.destroyAndRemove() - Destroys all functionality and removes the pickr element including the button.
• pickr.setColorRepresentation(type:String):Boolean - Change the current color-representation. Valid options are HEX, RGBA, HSVA, HSLA and CMYK, returns false if type was invalid.
• pickr.getColorRepresentation():String - Returns the currently used color-representation (eg. HEXA, RGBA...)
• pickr.applyColor(silent:Boolean):Pickr - Same as pressing the save button. If silent is true the onSave event won't be called.
• pickr.addSwatch(color:String):Boolean - Adds a color to the swatch palette. Returns true if the color has been successful added to the palette.
• pickr.removeSwatch(index:Number):Boolean- Removes a color from the swatch palette by its index, returns true if successful.

Static methods

Pickr

• Pickr.create(options:Object):Pickr - Creates a new instance.

Pickr.utils

• once(element:HTMLElement, event:String, fn:Function[, options :Object]) - Attach an event handle which will be fired only once
• on(elements:HTMLElement(s), events:String(s), fn:Function[, options :Object]) - Attach an event handler function.
• off(elements:HTMLElement(s), event:String(s), fn:Function[, options :Object]) - Remove an event handler.
• createElementFromString(html:String):HTMLElement - Creates an new HTML Element out of this string.
• eventPath(evt:Event):[HTMLElement] - A polyfill for the event-path event propery.
• removeAttribute(el:HTMLElement, name:String) - Removes an attribute from a HTMLElement and returns the value.
• createFromTemplate(str:String) - See inline doumentation.
• resolveElement(val:String|HTMLElement) - Resolves a HTMLElement, supports >>> as shadow dom selector.
• adjustableInputNumbers(el:InputElement, mapper:Function) - Creates the possibility to change the numbers in an inputfield via mouse scrolling. The mapper function takes three arguments: the matched number, an multiplier and the index of the match.

Use this utils carefully, it's not for sure that they will stay forever!
