Hi,
[s]thank you in your advice.
>aSubject.notificationCallbacks instanceof
>Components.interfaces.nsIXMLHttpRequest) {
I check your code, but it returned false on Firefox 3 beta4.
I get interfaces of notificationCallback.
getInterfacesByObject(subject.notificationCallbacks, false)
=>
- nsIExpatSink
- nsIInterfaceRequestor
-nsIRequestObserver
-nsIStreamListener
-nsIChannelEventSink
How can I distinguish XMLHttpRequest from normal HttpRequest?
The source code of getInterfacesByObject is follwing.
function getInterfacesByObject(obj, excludeSupports) {
if (!excludeSupports) {
excludeSupports = true;
}
var ifaces = [];
for (var iface in Ci) {
if (obj instanceof Ci[iface]) {
if (excludeSupports && iface == "nsISupports") {
continue;
}
ifaces.push(Ci[iface]);
}
}
return ifaces;
}
