MenuItem.documentURLPatterns

By Opera Software

Description:

The documentURLPatterns attribute is an array of rules specifying which domains a menu item should be visible on. If this attribute is null (default) or an empty array then the menu item will appear on all domains. Note that * can be used as a wildcard.

Syntax:

DOMString[] documentURLPatterns

Example:

The following example creates an item in the context menu only for pages in the opera.com domain.

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

//
// 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: 'Translate this page',
    documentURLPatterns: [
      'http://opera.com/*',
      'https://opera.com/*',
      'http://*.opera.com/*',
      'https://*.opera.com/*'
    ],
    onclick: function(event) {
      doTranslate(event.pageURL);
    }
  }

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