The hasStorageAccess() method of the Document interface returns a Promise that resolves with a boolean value indicating whether the document has access to its first-party storage.
See Storage Access API for more information.
hasStorageAccess()
None.
A Promise that resolves with a boolean value indicating whether the document has access to its first-party storage.
If the promise gets resolved and a user gesture event was being processed when the function was originally called, the resolve handler will run as if a user gesture was being processed, so it will be able to call APIs that require user activation.
document.hasStorageAccess().then(hasAccess => { if (hasAccess) { // storage access has been granted already. } else { // storage access hasn't been granted already; // you may want to call requestStorageAccess(). } });
The API is currently only at the proposal stage — the standardization process has yet to begin. You can currently find specification details of the API at Apple's Introducing Storage Access API blog post, and WHATWG HTML issue 3338 — Proposal: Storage Access API.
