Show/Hide Div on Scroll
提问by Dan
I have a div that sits at the bottom of a slideshow that I want to disappear when the user scrolls or uses down arrow then reappears when scrolls back to the top. I am guessing this is incorporating the jquery scroll functionality?
我有一个位于幻灯片底部的 div，我想在用户滚动或使用向下箭头时消失，然后在滚动回顶部时重新出现。我猜这是结合了 jquery 滚动功能？

Here is my answer when you want to animate it and start fading it out after couple of seconds. I used opacity because first of all i didn't want to fade it out completely, second, it does not go back and force after many scrolls.
当您想为其设置动画并在几秒钟后开始淡出时，这是我的答案。我使用了不透明度，因为首先我不想让它完全淡出，其次，它在多次滚动后不会回退和强制。
$(window).scroll(function () {
var elem = $('div');
setTimeout(function() {
elem.css({"opacity":"0.2","transition":"2s"});
},4000);
elem.css({"opacity":"1","transition":"1s"});
});

$.fn.scrollEnd = function(callback, timeout) {
$(this).scroll(function(){
var $this = $(this);
if ($this.data('scrollTimeout')) {
clearTimeout($this.data('scrollTimeout'));
}
$this.data('scrollTimeout', setTimeout(callback,timeout));
});
};
$(window).scroll(function(){
$('.main').fadeOut();
});
$(window).scrollEnd(function(){
$('.main').fadeIn();
}, 700);
That should do the Trick!
这应该够了吧！
