jQuery滚动条上的div

Question

I have a top fixed div and then a main frame which contains two divs inside (left and right). I want to make the right div stick just under the top bar on scroll.

I've put up what I have here: http://jsfiddle.net/mhD9Y/2/

$(document).ready(function(){

var window_top = 41 - $(window).scrollTop();
  var div_top = $('#stop_scroll').offset().top;
  if (window_top > div_top)
    $('#right').addClass('stick');
  else
    $('#right').removeClass('stick');

});



 .stick {
        position: fixed !important;
        top: 41px !important;z-index: 5 !important;    -webkit-transition: all 1s ease;
    -moz-transition: all 1s ease;
    -o-transition: all 1s ease;
    transition: all 1s ease;
    }

The thing is that the script doesn't kick in at all.

thanks

Put your code with window scroll.

$(document).ready(function(){
    $(window).scroll(function(){
      var window_top = $(window).scrollTop() - 41;
      var div_top = $('.right').offset().top;
      if (window_top > 41) {
        if (!$('.right').is('.stick')) {
            $('.right').addClass('stick');
         }
      }  else
           $('.right').removeClass('stick');
    });
});

Either you change the id="right" to class="right"

OR

Change your css of the

.stick and add !important at the end of each attribute.

Script:

    $(document).ready(function(){
      $(window).scroll(function(){
        var window_top = $(window).scrollTop() - 41;
        var div_top = $('#stop_scroll').offset().top;
        console.log(window_top, div_top);
        if (window_top > div_top) {
             $('#right').addClass('stick');
        } else {
             $('#right').removeClass('stick');
        }
      });
    });

CSS:

    .stick {
        position: fixed !important;
        top: 41px !important;
    }
