Window: fence property
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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
js
window.fence.reportEvent({
eventType: "click",
eventData: JSON.stringify({ clickX: "123", clickY: "456" }),
destination: ["buyer", "seller"],
});
