I'm trying to figure out how to set and retrieve data without putting
it into a class, element, or anything else visible, and in the dom.
My site is integrating Facebook connect, and sometimes if a user
hasn't logged in, I bring them to the login, but I'm trying to
remember what function would have run if they were logged in so that I
can call that after they login.
currently i set the data like this
[code]
jQuery('ul#otherLogin').data('selectForLogin','getTracked');
[/code]
i then later try to get the value for 'selectForLogin like this
[code]
var refreshWhat=jQuery('div#otherLogin').data('selectForLogin');
[/code]
but i always get 'undefined';
i've looked at the documentation http://docs.jquery.com/Data,
but it leaves me with two questions
1) why is my data being set
2) do i have to 'remove' a data value? or do they just get overwritten
if I set it again?
any ideas?
