The data for the first and last message come from the body of the document. The modeless message is taken directly from the body by using an XPath expression into the model.
Note that the first event happens when you start to enter data in an input field. This is the
DOMFocusIn event. The other two use the
DOMActivate event which happens when you enter a return on the second example and press the button on the last example.
