Locker API Viewer shows Locker’s support of the standard DOM APIs in the Window, Document, and Element objects. The Secure Window, Secure Document, and Secure Element wrappers prevent use of APIs that are labelled Not Supported.
Click a secure wrapper in API Source to display the support status for its DOM APIs. Use search and filters to focus your view. The version number shows the earliest Locker API version that supports the DOM API.
Click Vote on up to three DOM APIs that you request to be supported in a future release.
