menuInstance.indexOf(item)
item A reference to an XML node that describes a menu item.
The index of the specified menu item, or undefined if the item does not belong to this menu.
Method; returns the index of the specified menu item within this menu instance.
The following example creates a menu with two items from an XML data provider and then adds a third item to the menu and saves the reference that is returned by the addMenuItem() method. Next, it calls the indexOf() method by using the reference to obtain the index of the item and display it in the Output panel.
You first drag a Menu component and a Button component to the library and then add the following code to Frame 1:
/**
Requires:
- Menu component in library
*/
import mx.controls.Menu;
// Create an XML object to act as a factory.
var my_xml:XML = new XML();
// The item created next does not appear in the menu.
// The createMenu() method call (below) expects to
// receive a root element whose children will become
// the items. This is just a simple way to create that
// root element and give it a convenient name.
var menuDP_obj:Object = my_xml.addMenuItem("Edit");
// Add the menu items.
menuDP_obj.addMenuItem({label:"1st Item"});
menuDP_obj.addMenuItem({label:"2nd Item"});
// Create the Menu object.
var my_menu:Menu = Menu.createMenu(this, menuDP_obj);
var myItem_obj:Object = my_menu.addMenuItem({label:"That item"});
// Show and position the menus.
my_menu.show(100, 20);
var myIndex_num:Number = my_menu.indexOf(myItem_obj);
trace("Index of 'That Item': " + myIndex_num);
