The Sanitizer
interface of the HTML Sanitizer API
is used to sanitize untrusted strings of HTML, Document
and DocumentFragment
objects.
After sanitization, unwanted elements or attributes are removed, and the returned objects can safely be inserted into a document's DOM.
A Sanitizer
object is also used by the Element.setHTML()
method to parse and sanitize a string of HTML, and immediately insert it into an element.
The default configuration strips out XSS-relevant input by default, including <script>
tags, custom elements, and comments.
This configuration may be customized using constructor options.
