Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. 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 This method has been superceded by PushManager.subscribe().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));
}
