setting a cookie - should be easy.

this is not specifically behaviour related, but i thought i would risk
asking anyway.

i am working on a script that triggers a blind down or blind up effect
by clicking on a particular link. it then remembers the status of that
choice by setting a cookie.

setCookie(this. parentNode.id, '', 365);

new Effect.BlindUp( 'tool-box');
Element.addClas sName('tool-box', 'invisible');

that was taken directly from the artilcle but does not apply to my
situation. in the article he is applying the effects to the same
element that is clicked on, so 'this' is used in the function, where as
i am using 'tool-box', which is the id of the div that is getting
triggered.

so when i get the setCookie part, i need to rewrite it so that it
associates itself with the div 'tool-box instead of 'this'. basically i
just do not know the proper syntax. i tried...

but that did not seem to work for me.

any thoughts?

p.s. i did not include the cookie stuff because i do not think it is
needed, but if you think it would be helpful, i can included or you can
find it in the article.

The reason the script uses "this" is because it is attaching a behaviour
to a class; that is, all elements belonging to that class will inherit
the behaviour, which will affect the element itself when clicked.
Unless you want all of the links in a class to have exactly the same
effect (which could be to roll up some other element named "toolbox"),
you need to put a different onclick event in each link, which calls a
function with the appropriate name given as a parameter.
