提问by acctman
Can anyone suggest a good simple jQuery vertical autoscroller script? one that's not bloat, I just need for it to auto start and scroll 6 or more liin a div. i tried the jquery.autoscroll.jsbut couldn't get it to auto start.
谁能推荐一个简单的jQuery垂直自动滚动脚本？一个不膨胀的，我只需要它自动启动并li在一个 div 中滚动 6 个或更多。我尝试了jquery.autoscroll.js但无法让它自动启动。
$.fn.autoscroll.defaults = {
start: {
step: 50,
scroll: true,
direction: "down",
pauseOnHover: true
},
delay: 5000,
ffrw: {
speed: "fast",
step: 100
}
};

var div = $('div.autoscrolling');
var scroller = setInterval(function(){
var pos = div.scrollTop();
div.scrollTop(++pos);
}, 100)?
工作演示。
EDIT:
编辑：
To stop scrolling when the div has scrolled to the bottom add the following check at the end of the above function() {}-
要在 div 滚动到底部时停止滚动，请在上述末尾添加以下检查function() {}-
if($(this).scrollTop() + $(this).innerHeight() >= this.scrollHeight)
clearInterval(scroller);
}

Robin's answer didn't quite do the trick for me, for several reasons, so here's a modified and extended version of his approach:
出于多种原因，Robin 的回答对我来说并没有完全奏效，因此这是他的方法的修改和扩展版本：
var div = $('.scrollbit');
$('.scrollbit').bind('scroll mousedown wheel DOMMouseScroll mousewheel keyup', function(evt) {
if (evt.type === 'DOMMouseScroll' || evt.type === 'keyup' || evt.type === 'mousewheel') {
}
if (evt.originalEvent.detail < 0 || (evt.originalEvent.wheelDelta && evt.originalEvent.wheelDelta > 0)) {
clearInterval(scrollbit);
}
if (evt.originalEvent.detail > 0 || (evt.originalEvent.wheelDelta && evt.originalEvent.wheelDelta < 0)) {
clearInterval(scrollbit);
}
});
var scrollbit = setInterval(function(){
var pos = div.scrollTop();
if ((div.scrollTop() + div.innerHeight()) >= div[0].scrollHeight) {
clearInterval(scrollbit);
}
div.scrollTop(pos + 1);
}, 100);

The autoscroll.js download at github has the wrong files in the download. If you search there, you can find them.
github 上的 autoscroll.js 下载文件中包含错误的文件。如果你在那里搜索，你可以找到它们。
