While Mouse press event. Prototype JS or Javascript

I would like to know if someone knows how to make a function repeat over and over while the mouse is press, I don't know how to make it work. I know in prototype you can take events like 

$('id').observe("click",function(event){}) 
$('id').observe("leave",function(event){})
$('id').observe("change",function(event){})
//etc...

but is something like $('id').observe("whilemousepress",function(event){}) :P
//I know there is not any event in Javascript but I would like to emulate.

Solution

  • I can't comment on the prototype specifics, but you could probably do this by creating an interval using setInterval() that is started on mousedown and is stopped using .clearInterval() on mouseup.
