Well, the only reason that '$mydisplay' is in the url rather than 5,
is because variable substitution only happens automatically in php
when using double quote strings, not single quote.
'url' => "/books/lister/?id=1&display=$mydisplay",
will do what you want.
Or are you asking how to modify this parameter using Javascript, based
upon the user interaction in a page?
