Permissions: revoke() method
Note: This feature is available in Web Workers.
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The revoke()
method of the
Permissions
interface reverts a currently set permission back to its
default state, which is usually prompt
.
This method is called on the global Permissions
object
navigator.permissions
.
This method is removed from the main permissions API specification because its use case is unclear. Permissions are managed by the browser and the current permission model does not involve the site developer being able to imperatively request or revoke permissions. Browsers have shipped this API behind preferences but it's unlikely to reach the standards track. For more context, see the original discussion to remove permissions.revoke()
.
Syntax
revoke(descriptor)
Parameters
descriptor
-
An object based on the
PermissionDescriptor
dictionary that sets options for the operation consisting of a comma-separated list of name-value pairs. The available options are:name
-
The name of the API whose permissions you want to query. Each browser supports a different set of values. You can consult the Firefox values, the Chromium values, and the WebKit values.
userVisibleOnly
-
(Push only, not supported in Firefox — see the Browser compatibility section below) Indicates whether you want to show a notification for every message or be able to send silent push notifications. The default is
false
. sysex
(MIDI only)-
Indicates whether you need and/or receive system exclusive messages. The default is
false
.
Note: As of Firefox 44, the permissions for Notifications and Push have been merged. If permission is
granted (e.g. by the user, in the relevant permissions dialog),
navigator.permissions.query()
will return true
for both
notifications
and push
.
Note: The persistent-storage
permission allows an
origin to use a persistent box (i.e., persistent storage) for its
storage, as per the Storage API.
Return value
A Promise
that calls its fulfillment handler with a
PermissionStatus
object indicating the result of the request.
Exceptions
TypeError
-
Retrieving the
PermissionDescriptor
information failed in some way, or the permission doesn't exist or is currently unsupported (e.g.midi
, orpush
withuserVisibleOnly
).
Examples
This function can be used by an app to request that its own Geolocation API permission be revoked.
function revokePermission() {
navigator.permissions.revoke({ name: "geolocation" }).then((result) => {
report(result.state);
});
}
