opera.contexts.menu.onclick and MenuItem.onclick

By Opera Software

From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.


This property represents the function executed when a context menu item is clicked. This callback function will contain one argument of type MenuEvent.


The below example opens a new tab when the extension's menu item is clicked.

  The configuration file ('config.xml').
<?xml version='1.0' encoding='utf-8'?>
<widget xmlns="http://www.w3.org/ns/widgets">
    <feature name="opera:contextmenus"/>
// The background process (e.g. index.html)

if (opera.contexts.menu) {
  var menu = opera.contexts.menu;

  // Create a menu item properties object
  var itemProps = {
    title: 'Context Menu Example',
    type: 'folder'

  // Create a menu item with the specified properties
  var item = menu.createItem(itemProps);
  // Add the menu item to the context menu

  // Open a new tab when clicked
  item.onclick = function(event) {
    var tab = opera.extension.tabs.create();
