TrustedTypePolicyFactory: emptyHTML property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Web Workers.

The emptyHTML read-only property of the TrustedTypePolicyFactory interface returns a TrustedHTML object containing an empty string.

This object can be used when the application requires an empty string to be inserted into an injection sink.


A TrustedHTML object.


In the below example an empty string is to be inserted into the element. Therefore there is no need to create a policy, and the emptyHTML property can be used to insert the empty element when a Trusted Types object is expected.

el.innerHTML = trustedTypes.emptyHTML;
