HTMLIFrameElement: privateToken property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The privateToken property of the HTMLIFrameElement interface returns a string representation of an options object representing a private state token operation; this object has the same structure as the RequestInit dictionary's privateToken property.

This attribute mirrors the content of the associated <iframe> element's privateToken attribute.

Value

A string.

Examples

html
<iframe id="el" privateToken="{version: 1,operation: 'token-request'}">
</iframe>
js
const el = document.getElementById("el");
console.log(el.privateToken);
// Logs "{version: 1,operation: 'token-request'}"
