问题描述
我有一个div,我需要固定到屏幕的底部,直到它到达一些点后滚动,停在那里,留下来。
I've got a div which I need to be fixed to the bottom of the screen, until it reaches some point after scrolling and stop there and stay. If a user start scrolling back up - make it fixed again after passing that same point.
有关如何完成这项工作的任何建议吗?
Any ideas on how this can be accomplished?
编辑:(这里是我目前的代码不起作用)
(here's my current code which doesn't work)
$(window).scroll(function () {
if ($(this).scrollTop() < $(document).height() - 81) {
$('#bottom_pic').css('bottom', "0px");
}
else {
$('#bottom_pic').css('bottom', "81px");
}
});
CSS:
#bottom_pic
{
position: fixed;
bottom: 0px;
}
谢谢!
