The contextmenu event fires when the user attempts to open a context menu. This is typically triggered by clicking the right mouse button, or by pressing the context menu key. (In the latter case, the context menu is displayed at the bottom left of the focused element, unless the element is a tree, in which case the context menu is displayed at the bottom left of the current row.)

Note that this event will occur with any non-disabled right-click event and does not depend on an element possessing the contextmenu attribute.

Properties

Property Type Description
target Read only EventTarget The event target (the topmost target in the DOM tree).
type Read only DOMString The type of event.
bubbles Read only Boolean Whether the event normally bubbles or not.
cancelable Read only Boolean Whether the event is cancellable or not.
currentTarget Read only EventTarget The node that had the event listener attached.
relatedTarget Read only EventTarget For mouseover, mouseout, mouseenter and mouseleave events: the target of the complementary event (the mouseleave target in the case of a mouseenter event). null otherwise.
screenX Read only long The X coordinate of the mouse pointer in global (screen) coordinates.
screenY Read only long The Y coordinate of the mouse pointer in global (screen) coordinates.
clientX Read only long The X coordinate of the mouse pointer in local (DOM content) coordinates.
clientY Read only long The Y coordinate of the mouse pointer in local (DOM content) coordinates.
button Read only unsigned short The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left.
buttons Read only unsigned short The buttons being pressed when the mouse event was fired: Left button=1, Right button=2, Middle (wheel) button=4, 4th button (typically, "Browser Back" button)=8, 5th button (typically, "Browser Forward" button)=16. If two or more buttons are pressed, returns the logical sum of the values. E.g., if Left button and Right button are pressed, returns 3 (=1 | 2). More info.

[1] Only works for <textarea> elements and some <input> element types.

In Gecko this event is handled by an XUL ancestor element, even for HTML5 context menus, which are actually handled by the browser element's context menu. If an XUL ancestor element has a context or contextmenu attribute referencing a popup, then it will display when this event occurs (subject to the popupshowing event).
