Rails spinoffs - Nov 2007 - How to pass parameters to a function in Event.observe

Hi,

I would like to know (if it is possible) how to pass parameters to a
function in Event.observe

Example :
Event.observe(tag_id, "change", myfunction, false);

The function myfunction should have a specific behavoir according to
parameters :
function myfunction(param1, param2);

Thank you.

This is what a closure is for.

  Event.observe(tag_id, "change", function() { myfunction(param1,
param2) }, false)

In 1.6, you could also use the new curry function:

Event.observe(tag_id, ''change'', myfunction.curry(param1,
param2), false);
