menus.getTargetElement()

Returns the element for a given targetElementId

This method is available to all extension script contexts (content scripts, background pages and other extension pages) and returns the element for a given info.targetElementId , provided that the element still exists in the document where the method is invoked.

The method only works in the document that includes the right-clicked element and the targetElementId expires when the user opens another context menu.

注意： menus.getTargetElement only return the requested element if called in the same context as the document that contains the element, for example using content scripts (as shown in the example below).

An extension requires the "menus" permission to use this API.
