# <tt>:on_hide</tt>:: A Javascript expression that is called when the
# autocompletion div is hidden. The expression
# should take two variables: element and update.
# Element is a DOM element for the field, update
# is a DOM element for the div from which the
# innerHTML is replaced.
# <tt>:on_show</tt>:: Like on_hide, only now the expression is called
# then the div is shown.
