Advanced Color Picker In JavaScript – Colorize

An advanced color picker component that supports HEX/RGBa color formats, color names, pre-defined palette, etc.

How to use it:

1. Load the JavaScript colorize.js and Stylesheet colorize-style.css in the document.

<script src="colorize.js" ></script>
<link rel="stylesheet" href="colorize-style.css" />

2. Create an input field to trigger the color picker.

<div id="colorizer">
  <input id="color-input" type="text" value="rgba(255,0,0,1)">
</div>

3. Initialize the color picker and display the value of the selected color in the input field you just created.

document.getElementById( "color-input" ).addEventListener( "focus", function (e) {
  /* { "id" : null, "container" : "the container for widget(required)", "value" : "rgba(1,1,1,1)(required)" } */
  var data = {
      "id" : null,
      "container" : document.getElementById( "colorizer" ),
      "value" : document.getElementById( "color-input" ).value
  }
  var colorizer = new Gn8Colorize( data );
  colorizer.init().then( 
    success => {
      /* { "hex" : "#ff0000", "rgb" : "rgba(255,0,0,1)", "name" : "red", "theme" : "dark | light" } */
      document.getElementById( "color-input" ).value = success.rgb;
      console.log( success );
    }, error => {
      console.log( error );
    } 
  );
});
