    Summary

    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);
        }
      }
    }
