Document: parseHTMLUnsafe() static method

Baseline 2024

Newly available

Since April 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The parseHTMLUnsafe() static method of the Document object is used to parse a string of HTML, which may contain declarative shadow roots, in order to create a new Document instance.

The suffix "Unsafe" in the method name indicates that, while <script> elements are not evaluated during parsing, the method does not sanitize other potentially unsafe XSS-relevant input.

The resulting Document will have a content type of "text/html", a character set of UTF-8, and a URL of "about:blank"
