Constructs a MutationObserver object and sets its MutationCallback to callback.
The callback is invoked with a list of MutationRecord objects as first argument and the constructed MutationObserver object as second argument. It is invoked after nodes registered with the Observe(Node, IMutationObserverInit) method, are mutated.
callback - The callback.public static com.aspose.ms.System.IDisposable subscribe(Node target, MutationCallback callback, MutationObserverInit options)
@DOMNameAttribute(name="observe") public void observe(Node target, MutationObserverInit options)
Instructs the user agent to observe a given target (a node) and report any mutations based on the criteria given by options (an object). The options argument allows for setting mutation observation options via object members.
target - The target for observe.options - The observer options.@DOMNameAttribute(name="disconnect") public void disconnect()
Stops observer from observing any mutations. Until the observe() method is used again, observer’s callback will not be invoked.
