HTMLFencedFrameElement

Inherits properties from its parent, HTMLElement.

HTMLFencedFrameElement.allow Experimental

Gets and sets the value of the corresponding <fencedframe> allow attribute, which represents a Permissions Policy applied to the content when it is first embedded.

HTMLFencedFrameElement.config Experimental

a FencedFrameConfig object, which represents the navigation of a <fencedframe>, i.e. what content will be displayed in it. A FencedFrameConfig is returned from a source such as the Protected Audience API.

HTMLFencedFrameElement.height Experimental

Gets and sets the value of the corresponding <fencedframe> height attribute, which specifies the height of the element.

HTMLFencedFrameElement.width Experimental

Gets and sets the value of the corresponding <fencedframe> width attribute, which specifies the width of the element.

To set what content will be shown in a <fencedframe>, a utilizing API (such as Protected Audience or Shared Storage) generates a FencedFrameConfig object, which is then set as the value of the <fencedframe>'s config property.

The following example gets a FencedFrameConfig from a Protected Audience API's ad auction, which is then used to display the winning ad in a <fencedframe>:

const frameConfig = await navigator.runAdAuction({
  // ...auction configuration
  resolveToConfig: true,
});

const frame = document.createElement("fencedframe");
frame.config = frameConfig;
