opera.contexts.menu.addItem() and MenuItem.addItem()

This functionality has not landed in a stable Opera version yet, but you can use it already in Opera Next.

Description

This method adds a MenuItem to the context menu or a context menu item. The optional before parameter can be specified to indicate where in the menu the item should be added. To create a MenuItem see the createItem() method.

Parameters:

• item: The MenuItem to be added.
• before (optional): The item before which the new MenuItem should be added.

Syntax:

void addItem (<MenuItem> item, optional <MenuItem> before)

void addItem (<MenuItem> item, optional long before)

Example:

The example below creates and adds an item to the context menu. When it's clicked, the current page's URL is shown in the console.

if (opera.contexts.menu) {

    title: 'Context Menu Example',
    onclick: function(event) {
      console.log('Menu item clicked on ' + event.pageURL);
    }
  }

  menu.addItem(item);
}
