Package Exports

vanilla-picker
vanilla-picker/dist/vanilla-picker

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (vanilla-picker) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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'></script>

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) {

        /*
            You can get the color components from
                color.rgba
                color.hsla  (all values between 0 and 1, inclusive)
    
            ..or ready-to-use CSS values from
                color.rgbString
                color.rgbaString
                color.hslString
                color.hslaString
                color.hex   (8 digit #RRGGBBAA, not supported in all browsers)
        */

        parent.style.background = color.rgbaString;
    };

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

</script>

Options

var picker = new Picker({

    parent:        /* Which element the picker should be attached to */
    
    /* If the picker is used as a popup, where to place it relative to the parent */
    popup: 'right' (default)
           'left'
           'top'
           'bottom'
           false   /* No popup, just add the picker as a normal element on the page */

    alpha: true    /* Whether to enable adjusting the alpha channel */
    
    color:         /* Initial color for the picker        (or call picker.setColor()) */
    
    onChange:      /* Callback whenever the color changes (or set  picker.onChange) */
    
    onDone:        /* Callback when the user clicks "Ok"  (or set  picker.onDone) */

});
