ColorPicker Overview

The ColorPicker control lets users select a color by clicking on panels to adjust channels, such as hue, saturation, brightness and alpha. The control can be used as a drop-down for the InputColor control. You can use the value property to get or set the currently selected color.

HTML

<h1>ColorPicker</h1>
<div id="output">
  Select a background for me!
</div>
<div id="theColorPicker"></div> 

CSS

h1{
  margin: 10px;
}

.wj-colorpicker {
  margin: 10px;
}
#output {
  margin: 10px;
  float: left;
  font-size: 12px;
  border: 1px solid grey;
  padding: 12px;
}

Javascript

import * as input from '@mescius/wijmo.input';

function init() {
    // ColorPicker
    let theColorPicker = new input.ColorPicker('#theColorPicker', {
        showAlphaChannel: true,
        showColorString: true,
        valueChanged: (sender) => setBackground(sender.value)
    });
    
    // show the color that was selected
    function setBackground(color) {
        document.getElementById('output').style.background = color;
        theColorPicker.value = color;
    }
}

Also, you can customize the ColorPicker by changing values of the showAlphaChannel, showColorString, and palette properties. For detailed implementation, see the ColorPicker demo.
