The fence read-only property of the Window interface returns a Fence object instance for the current document context.

Fence objects are only available to documents embedded inside <fencedframe>s (loaded via FencedFrameConfigs) or <iframe>s (loaded via opaque URNs).

Note: See How do <fencedframe>s work? for some description around FencedFrameConfigs and opaque URNs.

Value

A Fence object instance, or null if the document context does not have access to a Fence object.

Examples

window.fence.reportEvent({
  eventType: "click",
  eventData: JSON.stringify({ clickX: "123", clickY: "456" }),
  destination: ["buyer", "seller"],
});
