PushManager.register()

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 register method is used to ask the system to request a new endpoint for notifications. This method has been superceded by PushManager.subscribe().

Syntax

var request = navigator.push.register();

Return

A DOMRequest object to handle the success or failure of the method call.

If the method call is successful, the request's result will be a string, which is the endpoint URL.

Note: if you do not need the URL any more, please use Pushmanager.unregister() to clean up after yourself.

Example

var req = navigator.push.register();

req.onsuccess = function(e) {
  var endpoint = req.result;
  debug("New endpoint: " + endpoint );
}

req.onerror = function(e) {
  debug("Error getting a new endpoint: " + JSON.stringify(e));
}
