Javascript - Scriptaculous - Effect Callback function

Question

I am using scriptaculous to perform a slidedown effect using the following code:

Effect.SlideDown('dom_element_id');

I then hide the button which initiates this effect using:

$('button_id').hide();

The issue is that the button is hidden before the animation effect is complete, I would like it to hide after the animation effect is complete. I could not find a callback parameter for Effect.SlideDown.

Can anybody help me out?

Thanks in advance.

Answer 1

you can pass the afterFinish option to pass a callback to be run after the effect has been completed.

Effect.SlideDown('dom_element_id', { afterFinish: function () {$('button_id').hide(); } } );

EDIT

Note that beforeFinish, afterFinish, beforeSetup, afterSetup, beforeUpdate and afterUpdate options can be used for any effects as they are part of Effect.Base.
