TrustedHTML: toJSON() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The toJSON() method of the TrustedHTML interface returns a JSON representation of the stored data.
Syntax
js
toJSON()
Parameters
None.
Return value
A string containing a JSON representation of the stored data.
Examples
The constant escaped is an object created via the Trusted Types policy escapeHTMLPolicy. The toString() method returns a string to safely insert into a document.
js
const escapeHTMLPolicy = trustedTypes.createPolicy("myEscapePolicy", {
createHTML: (string) => string.replace(/>/g, "<"),
});
const escaped = escapeHTMLPolicy.createHTML("<img src=x onerror=alert(1)>");
console.log(escaped.toJSON());
