我有一个简单的引导程序表,我试图自动垂直滚动。原因是表格将显示在屏幕上,表格中可能有10个项目或100个。所以我希望它能自动垂直滚动,这样用户就不必手动完成。到达终点后,它将重置并从顶部开始...
这是我到目前为止的标记:
<div class="table-responsive" style="height: 700px; overflow: auto;">
<table class="table table-bordered table-hover">
<thead>
<tr>
<th style="text-align: left; font-size: 23px;">#</th>
<th style="text-align: left; font-size: 23px;">Name</th>
<th style="text-align: left; font-size: 23px;">Description</th>
<th style="text-align: left; font-size: 23px;">Date</th>
</tr>
</thead>
<tbody>
<tr class="danger">
<td style="text-align: left; font-size: 16px;">1213</td>
<td style="text-align: left; font-size: 16px;">John Doe</td>
<td style="text-align: left; font-size: 16px;">my short description</td>
<td style="text-align: left; font-size: 16px;">Today's Date</td>
</tr>
</tbody>
</table>
</div>
注意:我希望只有HTML
和CSS
可以使用此功能。
有什么建议吗?

height
和scrollHeight
并对这些值执行动画需要JS (或jQuery)
var $el = $(".table-responsive");
function anim() {
var st = $el.scrollTop();
var sb = $el.prop("scrollHeight")-$el.innerHeight();
$el.animate({scrollTop: st<sb/2 ? sb : 0}, 4000, anim);
}
function stop(){
$el.stop();
}
anim();
$el.hover(stop, anim);
&#13;
.table-responsive{
height:180px; width:50%;
overflow-y: auto;
border:2px solid #444;
}.table-responsive:hover{border-color:red;}
table{width:100%;}
td{padding:24px; background:#eee;}

我高度建议使用javascript进行此操作。我只使用CSS尝试过一次,然后立即放弃了这个想法,但理论上这是可能的。以下演示在所有浏览器上都经过不测试,存在巨大的兼容性问题,并且是Safari上最蠢的事情。故事的道德:使用javascript。
@import url(https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css);
.table-responsive {
overflow-x: hidden;
}
table.table {
animation: ani linear 1s alternate infinite;
}
.table-responsive:hover {
overflow: auto;
}
.table-responsive:hover table.table {
animation: none ;
}
@keyframes ani {
0% { margin-left: 0; transform: translate3d(0%, 0, 0);}
25% { margin-left: 0; transform: translate3d(0%, 0, 0);}
75% { margin-left: 100%; transform: translate3d(-100%, 0, 0);}
100% { margin-left: 100%; transform: translate3d(-100%, 0, 0);}
}

下面的代码将不会重置,并从问题中的问题开始,从表格的顶部开始,但这将有助于未来的读者尝试滚动并自动循环表格行带有固定标题。
