Question

How can I make JavaScript (or jQuery) code only execute on the visitor’s first visit and never again until a cookie expires or is removed?

For example: $('#example').hide(); How can I prevent this code from executing for 7 days for this visitor?

Answer 1

try this tut: http://www.electrictoolbox.com/jquery-cookies/
set a cookie on first visit, read it out on any subsequent visit and do something like:

if($.cookie.isset() == true) {
    // do something
}
