The registrations method is used to ask the system about existing push endpoint registrations.
Syntax
var request = navigator.push.registrations();
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 an array of PushRegistration objects.
PushRegistration
Those objects are anonymous JavaScript objects with the following properties:
pushEndpoint
- A string representing the URL of the endpoint.
version
- The current version that the push endpoint is at.
Example
var req = navigator.push.registrations(); req.onsuccess = function(e) { if (req.result.length > 0) { for (var i = 0, l = req.result.length; i < l; i++) { console.log("Existing registration", req.result[i].pushEndpoint, req.result[i].version); } // Reuse existing endpoints. } else { // Register for a new endpoint. var register = navigator.push.register(); register.onsuccess = function(e) { console.log("Registered new endpoint", register.result); } } }
