menus.onClicked 编辑

Fired when a menu item is clicked.

For compatibility with other browsers, Firefox makes this event available via the contextMenus namespace as well as the menus namespace.

Syntax

browser.menus.onClicked.addListener(listener)
browser.menus.onClicked.removeListener(listener)
browser.menus.onClicked.hasListener(listener)

Events have three functions:

addListener(callback)

Adds a listener to this event.

removeListener(listener)

Stop listening to this event. The listener argument is the listener to remove.

hasListener(listener)

Check whether listener is registered for this event. Returns true if it is listening, false otherwise.

  id: "click-me",
  title: "Click me!",
  contexts: ["all"]
});

browser.menus.onClicked.addListener((info, tab) => {

              "in tab " + tab.id);
});
