ok!
My code is:
//register Observer
window.addEventListener("load", MyObserver, false);
function MyObserver(){
var observerService = Components.classes["@mozilla.org/observer-service;1"]
.getService(Components.interfaces.nsIObserverService);
// problem1: observer registered before or not ??
observerService.addObserver(ObserverFunction, "my-topic", false);
//i dont add anything to remove observer when window going to close
}
var ObserverFunction= {
observe: function (subject, topic, state) {
.....
}
}
i have to problems:
1. how can i find that observer is registered before or not ?
2. when i register observer only when first window opens every thing
is ok, when i open some other windows still every thing is ok and observer
works perfectly, but when i close first window while other windows are still
open the observer doesn't work anymore ?!
