MozAlarmsManager.add()

This API is available on Firefox or Firefox OS for installed or higher privileged applications.

The add method is used to retrieve a list of pending alarms.

Syntax

JavaScript
var request = navigator.mozAlarms.add(date, respectTimezone[, data]);

Properties

date
A Date object representing the time the alarm must be fired.
respectTimezone
A string that indicates if the alarm must be fired respecting the timezone set with the date. Possible values are ignoreTimezone or honorTimezone.
data Optional
An arbitrary JavaScript object with data to be stored with the alarm.

Return

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

If the method call is successfull, the request's result will be a number representing the id of the alarm.

Example

JavaScript
var alarm = {
  date: new Date(<code class="js string">"July 27, 2013 20:00:00"</code>),
  respectTimezone: 'ignoreTimezone',
  data: {
    message: "Do something dude!"
  }
};

var request = navigator.mozAlarms.add(alarm.date, alarm.respectTimezone, alarm.data);

request.onsuccess = function () {
  console.log('A new alarm has been set:' + this.result);
  alarm.id = this.result; // get the id of the new alarm.
}

request.onerror = function () {
  console.log('operation failed: ' + this.error);
}

Note: You need to use the same URL for setting and receiving an alarm. For example, If you invoke navigator.mozAlarms.add() on foo.html or index.html?foo=bar, but have { "alarm": "/index.html" } in your manifest messages field, you'll never receive the alarm.
