javascript - Making a div always visible while scrolling through another specific div -

i've created image upload widget in webapp, want widget visible while filling specific div beingness apart of of huge form ( in div need come in image urls provided widget ), here scenario :

to accomplish did next :

$().ready(function() { var $scrollingdiv = $("#scrollingdiv"); $(window).scroll(function(){ $scrollingdiv .stop() .animate({"margintop": ($(window).scrolltop() + 30) + "px"}, "slow" ); }); });

assuming scrollingdiv id of widget ( div3 ).

the problem i'm facing when scroll on div1, scrollingdiv keeps pushing bottom, can't see end of form because of :

my question : how can disable scrolling tracking when div3 collapses bottom of div2 ?
