jquery - Disapear element when off screen -
i'm trying disapear element when of screen , appear new one. problem is, element disapear if it's not off screen on every scroll.
here code:
$(window).scroll(function () { scrollhide('#zabiegi'); }); function scrollhide(sectionid) { if ($(window).width() < 968) { $(sectionid).each(function () { if (($(sectionid).find('.two').offset().top - $(window).scrolltop()) < 20) { $(sectionid).find('.two').stop().fadeout( "slow", function() { $(sectionid).find('.one').fadein(); updatemargin(sectionid,'.one'); }); } }); } } i've tryied different approach time - nothing happens , if statement give false.
$(window).scroll(function () { scrollhide('#zabiegi'); }); function scrollhide(sectionid) { if ($(window).width() < 968) { $(sectionid).each(function () { var off = $(sectionid).find('.two').offset(); var t = off.top; var h = $(sectionid).find('.two').height(); var doch = $(window).height(); console.log(t > 0 && t + h < doch); if (t > 0 && t + h < doch) { $(sectionid).find('.two').stop().fadeout( "slow", function() { $(sectionid).find('.one').fadein(); updatemargin(sectionid,'.one'); }); } }); } }
ok, i've found solution. problem in conditional statement if. here code:
function scrollhide(sectionid) { if ($(window).width() < 968) { $(sectionid).each(function () { if (($(sectionid).find('.two').offset().top + $(sectionid).find('.two').outerheight() - $(window).scrolltop()) < 0 ) { $(sectionid).find('.two').stop().fadeout( "slow", function() { $(sectionid).find('.one').fadein(); updatemargin(sectionid,'.one'); }); } }); } }); but still got problem... above script works when scroll down not ... i've added conditional statement:
if (($(sectionid).find('.two').offset().top + $(sectionid).find('.two').outerheight() - $(window).scrolltop()) < 0 || ($(sectionid).find('.two').offset().top - $(sectionid).find('.two').outerheight() + $(window).scrolltop()) < 0 ) { and in console.log output ok - shows 0 when above element, still not working...
