You can use the readyState property to query the current state of the element when the HTMLNamespaceEvents::onreadystatechange event fires.
All elements expose an HTMLNamespaceEvents::onreadystatechange event. The following objects always fire the event because they load data: applet, document, frame, frameSet, iframe, img, link, object, script, and xml elements. Other objects will only fire the HTMLNamespaceEvents::onreadystatechange event when a DHTML Behavior is attached.
When working with behaviors, wait for the HTMLNamespaceEvents::onreadystatechange event to fire and verify that the readyState property of the element is set to
completeto ensure that the behavior is completely downloaded and applied to the element. Until the HTMLNamespaceEvents::onreadystatechange event fires, if you use any of the behavior-defined members before attaching the behavior to the element, a scripting error can result, indicating that the object does not support that particular property or method.
