Like this?:
function filterHandler(evt){this.fire('check:filter');}
$('filter').observe('keyup',
filterHandler).observe('click',filterHandler).observe('focus',
filterHandler).observe('blur', filterHandler);
See Observe Documentation: http://www.prototypejs.org/api/event/observe
As the Event.Observe function returns the element the event listener
is being applied too you can just call 'observe' in tandem. I also
created a function named 'filterHandler' that each event listener will
call as they all run the same code, this makes it easier if you wish
to make a change to the function and removes the (assumed) needless
repetition, however if you intend to call different functions with
each event listener use the code below:
$('filter').observe('keyup', function(evt)
{this.fire('check:filter');}).observe('click',function(evt)
{this.fire('check:filter');}).observe('focus', function(evt)
{this.fire('check:filter');}).observe('blur', function(evt)
{this.fire('check:filter');});
Hope this helps,
Chris
