performAction(for:)

Performs the extension action associated with the specified tab or performs the default action if nil is passed.

Declaration

func performAction(for tab: (any WKWebExtensionTab)?)

Parameters

tab:
The tab for which to perform the extension action, or nil to perform the default action.

Discussion

Performing the action will mark the tab, if specified, as having an active user gesture. When the tab parameter is nil, the default action is performed. The action can either trigger an event or display a popup, depending on how the extension is configured.

If the action is configured to display a popup, implementing the appropriate web extension controller delegate method is required; otherwise, no action is performed for popup actions.
