MozSmsManager.getMessages(filter, reverseOrder)
Gets messages, which are specified using a MozSmsFilter object. The order can be reversed using a boolean as a second parameter. A DOMCursor is returned.

MozSmsManager.markMessageRead(id, isRead)
Marks a message with the specified id as read or unread depending on the Boolean isRead. A DOMRequest object is returned.
MozSmsManager.send(number, message)

MozSmsManager also inherits the methods from EventTarget.

Register an event handler of a specific event type on the EventTarget.
Removes an event listener from the EventTarget.
Dispatch an event to this EventTarget.

Additional methods for Mozilla chrome code

Mozilla extensions for use by JS-implemented event targets to implement on* properties. See also WebIDL bindings.

  • void setEventHandler(DOMString type, EventHandler handler)
  • EventHandler getEventHandler(DOMString type)


This is a non standard implementation, but it is discussed at W3C as part of the System Application Working Group.
