When a popup attached via the
context attributes is
opened, the XUL document's
popupNode property is set to the node that was
clicked on. This will be the target of the mouse event that activated the popup. If the
popup was opened via the keyboard, the popup node may be set to null. Typically, this
property will be checked during a popupshowing event handler for a context menu to
initialize the menu based on the context.
This property is only set for popups attached via the
context attributes. For other types of popups, the value is not changed. In
these other cases, for example when calling the popup's showPopup method, you may
wish to set the
popupNode property directly beforehand.
This property applies only to XUL documents.
var node = document.popupNode;
<menupopup id="toolbarContextMenu"> ... <menuitem oncommand="mailNewsCore.deleteButton(document.popupNode)"> ... </menupopup>
