Original Source

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

js-nolint
browser.menus.onClicked.addListener(listener)
browser.menus.onClicked.removeListener(listener)
browser.menus.onClicked.hasListener(listener)

Events have three functions:

  • addListener(listener)
    • : 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.

Parameters

  • listener
    • : The function called when this event occurs. The function is passed these arguments:
      • info
        • : {{WebExtAPIRef('menus.OnClickData')}}. Information about the item clicked and the context where the click happened.
      • tab
        • : {{WebExtAPIRef('tabs.Tab')}}. The details of the tab where the click took place. If the click did not take place in or on a tab, this parameter will be missing.

Examples

This example listens for clicks on a menu item, then log the item's ID and the tab ID:

js
browser.menus.create({
  id: "click-me",
  title: "Click me!",
  contexts: ["all"],
});

browser.menus.onClicked.addListener((info, tab) => {
  console.log(`Item ${info.menuItemId} clicked in tab ${tab.id}`);
});
