Ajax-enabling JSF applications
JSF allows us to easily implement Ajax (Asynchronous JavaScript and XML) functionality into our web applications by simply employing the <f:ajax> tag and CDI named beans, without needing to implement any JavaScript code or having to parse JSON strings to implement Ajax with JSF.
The following illustrates a typical usage of the <f:ajax> tag:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
