jquery - make div stick to the top of the screen and stop before hitting the footer

Question

I'm trying to make a div stick to the header once the user has started scrolling down the page . I found the example How can I make a div stick to the top of the screen once it's been scrolled to?

I used the code that has 24 votes . Live demo.

PROBLEMS : 1. I want to make the div stop before hitting the footer. i don't want to show it over the footer . 2. I don't know why this works with jquery 1.3.2 but not with 1.5.2 or a later version .

ofcourse any other jquery code / plugin or ideea would be great!

Answer 1

$(window).load($(function()
{
    var elem = $("#scroller");
    var top = elem.offset().top;
    var maxTop = $("#footer").offset().top - elem.height();
    var scrollHandler = function()
    {
      var scrollTop = $(window).scrollTop();
      if (scrollTop<top) {
        elem.css({position:"relative",top:""})//should be "static" I think
      } else if (scrollTop>maxTop) {
        elem.css({position:"absolute",top:(maxTop+"px")})
      } else {
        elem.css({position:"fixed",top:"0px"})
      }
    }
    $(window).scroll(scrollHandler);scrollHandler()

}));
