More AJAX Page
This page demonstrates how AJAX
behaviour can also be given to a Submit component just by adding the updateComponents parameter,
and how the update can apply to a group of components.
Echo (this component IS within the AJAX update group): abc
Echo (this component IS NOT within the AJAX update group): abc
Some statistics: the AJAX response is around 350 bytes, whereas the non-AJAX response is over 6,000 bytes!
