MenuEvent.srcElement

This documentation relates to Opera's now deprecated .oex Extension API framework for Opera versions <= 12.15 and also provided by our OEX2NEX shim library.

For the latest Opera Extensions API documentation for Opera versions > 12.15 please consult the latest Opera Extensions API documentation online.

Description:

The srcElement attribute is the in-page DOMNode object on which the current event was fired. If the event was fired in a background process this attribute will be null.

Syntax:

readonly DOMNode srcElement

Example:

In this example, a menu item is added to the context menu for images only. When the menu item is clicked, the image will be opened in a new tab.

<!-- 
  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. '/background.js'). 
//

if (opera.contexts.menu) {
  var menu = opera.contexts.menu;
  
  // Create a menu item properties object
  var itemProps = {
    contexts: ['editable'],
    title: 'User agent'
  }

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

//
// An injected script (e.g. '/includes/injected.js').
//

(function() {
  // Listen for the context menu being clicked
  opera.contexts.menu.onclick = function(menuEvent) {
    // Insert the browser user agent string into the editable element
    menuEvent.srcElement.value = window.navigator.userAgent;
  };
})();
