HTMLIFrameElement: sandbox property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The sandbox read-only property of the HTMLIFrameElement interface returns a DOMTokenList indicating extra restrictions on the behavior of the nested content.
It reflects the sandbox attribute of the <iframe> element.
Value
A DOMTokenList. Each item must be one of the tokens listed in the sandbox attribute of the <iframe> element.
Examples
html
<iframe
id="el"
title="example"
src="https://example.com"
sandbox="allow-same-origin allow-scripts"></iframe>
js
const el = document.getElementById("el");
console.log(Array.from(el.sandbox)); // Output: ["allow-same-origin", "allow-scripts"]
el.sandbox = "";
console.log(Array.from(el.sandbox)); // Output: []
