When reading this section, you'll see how all the pieces listed in the preceding steps fit together. Create the PhaseListener class, which handles the AJAX request, interacts with the custom component, and returns an XML document that contains the updated data.
This function looks up all the tags with the class name of dlabelPlainText with the help of the getElementsByClass helper function.
This section does not cover the JavaScript to color the table cells yellow in response to onmouseover events and to render the components in response to onclick events.
Languages English Back to top     Who Can Benefit Students who can benefit from this course are architects, domain experts, Java and web applications developers. A typical PhaseListener implementation checks the URLs it receives from the script tags to determine how it will handle an AJAX request. Dojo is a robust and mature open-source JavaScript library that offers numerous widgets for dynamic Web development. all :       document. During the JavaServer Faces request processing lifecycle, the framework invokes the custom component's phase listener, which is registered in the component's faces-config. CollabNet is a registered trademark of CollabNet, Inc. As AJAX and the various AJAX frameworks mature, problems such as the browser incompatibilities will likely disappear.
These APIs also give developers a way to programmatically handle events on components, as well as convert and validate input data. The rest of this tutorial assumes that you know the steps for creating a custom component.
Using a phase listener is only one of several ways to handle JavaServer Faces technology requests.
The user enters a value in the field and clicks the Update Me button to update the data. The basic steps for including AJAX in a custom component are: Create necessary JavaScript functions, leveraging DOJO as much as possible. In this tutorial, you'll see how to use DOJO and JavaServer Faces technology to include AJAX functionality in a custom component. In the Page Navigation editor, right-click and choose New Page.
The application has been extracted from the tutorial for use in these articles. With the DOJO JavaScript toolkit, it's even easier for component developers to add this functionality.
The object that processed the request returns an XML document containing any updates that need to go to the client.
Creating and using custom components that include Ajax functionality does not necessarily reduce the amount of Ajax-related coding. Care has to be taken to only transfer relevant data at rates that can be digested by the target platform.
Unlike JBI, some technologies such as Servlets currently have a little catching up to do until such asynchronous, event driven responses are dealt with in a standardized way and fit well.
Central to the technology is a powerful component model. DLabelPhaseListener, which processes the AJAX request, exchanges the data with the server-side object, and returns the XML data to the client.
In addition, developers can expose the JavaScript in these JavaServer Faces-developed AJAX-capable components to enable even more powerful interactions.

Instead of requiring page authors to include JavaScript code on the page itself, component developers can encapsulate it inside the component.
The JSP page also includes the code that maps the mouseover event to a JavaScript technology function that handles the event. Written by experts directly involved in developing this important technology, JavaServer Faces: The Complete Reference fully explains every aspect of JSF.
Well, first imagine that you do an HTTP GET request as with any old AJAX framework. CollabNet is a registered trademark of CollabNet, Inc.
First of all, it frees developers from writing more common JavaScript functions by providing pluggable  JavaScript libraries geared toward particular tasks, such as event-handling. js page containing the client-side JavaScript code necessary for the AJAX interactions.
jsp pages of the Editable Label application include several dLabel tags. He has written about Solaris and Java technologies for longer than he likes to admit, composing everything from man pages to technical white papers.
