拡張機能のサイドバーのプロパティを取得、設定します。
サイドバー はブラウザーウィンドウのウェブページの隣の、右側か左側にあるペインです。ブラウザーはユーザーが利用できるサイドバーを見て、表示するサイドバーを選択できる UI を提供します。manifest.json の sidebar_action
キーを使って、拡張機能は自身のサイドバーを定義できます。ここで述べる sidebarAction
API を使って、拡張機能はサイドバーのプロパティを設定、取得できます。
sidebarAction
API は {{WebExtAPIRef("browserAction")}} API と緊密にモデリングされています。
sidebarAction API は Opera の sidebarAction API を元にしていますが、次のものはサポートされていません: setBadgeText()
, getBadgeText()
, setBadgeBackgroundColor()
, getBadgeBackgroundColor()
, onFocus
, onBlur
.

API.
