jquery - How to hide fixed DIV when footer is visible on screen? -


i have fixed sidebar, visible along page when scrolling down.

the problem - in cases - sidebar getting on footer when reaching bottom of page.

i want hide sidebar when footer visible on screen avoid that. how can it?

try this:

var isscrolledintoview = function(elem) {     var $elem = $(elem);     var $window = $(window);      var docviewtop = $window.scrolltop();     var docviewbottom = docviewtop + $window.height();      var elemtop = $elem.offset().top;     var elembottom = elemtop + $elem.height();      return ((elembottom <= docviewbottom) && (elemtop >= docviewtop)); }  $(window).on('scroll', function () {     $('#sidebar').toggle(!isscrolledintoview('#footer')); });

reference: check if element visible after scrolling

the function called on window scroll , check if footer visible. if visible, hides sidebar else shows.
