Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The Element.openOrCloseShadowRoot read-only property represents the shadow root hosted by the element, regardless if its mode is open or closed. Use Element.attachShadow() to add a shadow root to an existing element.

Syntax

var shadowroot = element.shadowRoot;

Value

A ShadowRoot object instance, regardless if its mode is set to open or closed, or null if no shadow root is present. (See Element.attachShadow() for further details).

Specifications

This property is not part of any specification.
