This tag creates an HTML link to a controller action that generates an AJAX request when it is clicked. The exact Javascript used to fire off the AJAX request depends on which Javascript library is used. This tag also requires the use of either the <g:
javascript/> or <g:
setProvider/> tags. See the
AJAX section of the user guide to find out more.
