- ephemeral - a message that just appears briefly and goes away by itself
- modeless - a message you can ignore for now
- modal - a message the user must acknowledge before you go on
Here is a sceen image with the ephemeral message showing:

A message will appear for just a moment.</p> <xf:input> <xf:label>Ephemeral message: </xf:label> <xf:message level="ephemeral" ev:event="DOMFocusIn">This is an ephemeral message. Don't worry, I go away after a few seconds.</xf:message> </xf:input> <br/> <p>Press enter in the input field to get a modeless message:</p> <xf:input> <xf:label>Modeless message input: </xf:label> <xf:message level="modeless" model="myModel" ref="/MyMessage" ev:event="DOMActivate"/> </xf:input> <br/> <p>A standard and intrusive modal message that must be dismissed:</p> <xf:trigger> <xf:label>Press for a modal message</xf:label> <xf:message level="modal" ev:event="DOMActivate">This is a modal message.</xf:message> </xf:trigger> </body> </html>
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.
