メニューアイテムがクリックされたときに発火します。
他のブラウザとの互換性のためにFirefoxはこのイベントを名前空間contextMenusとmenuを経由して利用可能にしています。
書式
browser.menus.onClicked.addListener(listener) browser.menus.onClicked.removeListener(listener) browser.menus.onClicked.hasListener(listener)
イベントは3つの関数を持ちます:
addListener(callback)- このイベントのリスナーを追加します。
removeListener(listener)- リスニングを停止します。引数
listenerは削除するリスナーです。 hasListener(listener)listenerが登録されているかどうかを調べます。trueが返ればリスニング中、そうでなければfalseが返ります。
