dom.openOrClosedShadowRoot()

Gets the open shadow root or the closed shadow root hosted by the specified element. If the shadow root isn't attached to the element, it will return null.

Note: In Firefox, the equivalent property is element.openOrClosedShadowRoot. This read-only property represents the shadow root hosted by the element, regardless of whether its mode is open or closed.

Use Element.attachShadow() to add a shadow root to an element.

Syntax

let shadowRoot = browser.dom.openOrClosedShadowRoot(
  element,    // HTMLElement
)

Parameters

element

HTMLElement. The host element.

Return value

A ShadowRoot object instance, regardless of whether its mode is set to open or closed, or null if no shadow root is present.
