javascript - if element offset top is at 10% of viewport -



javascript - if element offset top is at 10% of viewport -

i execute function , observe when element.offset().top @ more or less 10% of viewport(window) when scroll. how can proceed?

i have @ moment.

$(window).on('scroll', function() { var wst = $(this).scrolltop(); var wh = $(this).height(); var elpos = wrapper.offset().top; if (wst >= elpos) { console.log('snoop doggy dog'); } });

thanks help.

note: it's element position top needs @ 10% of window. not 10% of document. thanks.

i have written different implementation help accomplish task. explain rest in snippet comments.

$(window).on('scroll', function() { /* onscroll */ /* calculate if scroll position > 10% */ if($(document).scrolltop() > (0.1 * $(document).height())) { console.log('scroll passed 10%'); } else { /* less 10% */ } });
