  <button type="button" class="kolorfield-open kolorfield-value" data-kolorfield-style-prop="background-color"></button>
</div>

The kolorfield Function

Initiates kolorfield on any element that has the kolorfield class. This should be a container around your color input.

Example

window.addEventListener('load', function () {
  kolorfield()
})

Attributes/Classes

• The kolorfield-input class - Any input element with this class will have it's value set to the selected color any time the color is changed. The color will also be set to any value that is entered into this input field.

• The kolorfield-open class - Any element with this class will open the color picker when clicked.

• The kolorfield-value class - Any element with this class will have it's text content set to the color when the color is changed. If this element is an input, it's value will be updated instead of text content.

• The data-kolorfield-style-prop attribute - Set this attribute to a style property (like background or color) on an element to have it's style updated when the color is changed. Multiple style properties can be defined by separating them with a comma (ie. background,color).

JavaScript Methods

The containing kolorfield element (the element with the kolorfield class) will have the following methods attached to it available for use:

var color = document.querySelector('.color')

color.open() // Opens the color picker

color.set('#00ff00') // Sets the color

var currentColor = color.get() // Gets the current color

// The `change` event bubbles up to the containing element so you can detect changes like so:
color.addEventListener('change', function () {
  document.body.style.setProperty('--color', event.target.value)
})
