pageAction.onClicked

Fired when a page action icon is clicked. This event will not fire if the page action has a popup.

To define a right-click action, use the {{WebExtAPIRef('contextMenus')}}  API with the “page_action” {{WebExtAPIRef('contextMenus/ContextType', 'context type', '', 'nocode')}} .

Syntax

browser.pageAction.onClicked.addListener(listener)
browser.pageAction.onClicked.removeListener(listener)
browser.pageAction.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)
  • : Checks whether a 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:
    • tab
      • : A {{WebExtAPIRef('tabs.Tab')}}  object representing the tab whose page action was clicked.
    • OnClickData
      • : An object containing information about the click.
        • modifiers
          • : An array. The keyboard modifiers active at the time of the click, being one or more of Shift, Alt, Command, Ctrl, or MacCtrl.
        • button
          • : An integer. Indicates the button used to click the page action icon: 0 for a left-click or a click not associated with a mouse, such as one from the keyboard and 1 for a middle button or wheel click. Note that the right-click is not supported because Firefox consumes that click to display the context menu before this event is triggered.

Examples

When the user clicks the page action, hide it, and navigate the active tab to “https://giphy.com/explore/cat”:

let catGifs = "https://giphy.com/explore/cat";

browser.pageAction.onClicked.addListener((tab) => {
  browser.pageAction.hide(tab.id);
  browser.tabs.update({ url: catGifs });
});

browser.pageAction.onClicked.addListener(() => {});
