EyeDropper: open() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The EyeDropper.open() method starts the eyedropper mode, returning a promise which is fulfilled once the user has selected a color and exited the eyedropper mode.

Syntax

js

open()
open(options)

Parameters

options Optional

An options object to pass an AbortSignal signal:

signal

An AbortSignal. The eyedropper mode will be aborted when the AbortSignal's abort() method is called.

Return value

A Promise that eventually resolves when the user selects a pixel color from the screen.

The promise resolves to an object with the following property:

sRGBHex

A string representing the selected color, in hexadecimal sRGB format (#aabbcc).

Exceptions

Exceptions are not thrown but returned when the Promise is rejected. The promise is rejected in two cases:

  • When the user dismisses the eyedropper mode by pressing the Escape key.
  • When the eyedropper mode is aborted by the AbortController passed as an argument to open().
