    Question How To show hidden Div content based on cookie?

    Anyone know the code for this?

    Here's the logic I need:

    Get cookie value 1
    Get cookie value 2
    Get cookie value 3

    If cookie 1 = a or cookie 2 = b or cookie 3 = c then show div tag 1

    If cookie 1 = d or cookie 2 = f or cookie 3 = g then show div tag 2

    I don't work much with cookies, but you could probably do it.

    Just take document.cookie and split(';') then you have your key:value pairs right there.

    If cookie 1 = d or cookie 2 = f or cookie 3 = g then show div tag 2
    Why check for a, b, or c if the result is the same --> show div tag?
    Just set one variable and check for 0, 1 or false, true.
    ie;
    if a or b or c, set variable = 0
    if d or e or f, set variable = 1
    set cookie to variable.

    When you return to program, check contents of cookie variable
    if variable = 0, show div tag 1
    if variable = 1, show div tag 2
