HTMLScriptElement: integrity property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.

The integrity property of the HTMLScriptElement interface is a string that contains inline metadata that a browser can use to verify that a fetched resource has been delivered without unexpected manipulation.

It reflects the integrity attribute of the <script> element.

Value

A string.
