列表无缝滚动和列表可切换的无缝滚动,如下图:

界面

 Css如下所示:
<style>
* {
margin: 0;
padding: 0;
}
 
li {
list-style: none;
}

.donation_list .box{
margin-top: 20px;
height: 330px;
overflow: hidden;
background:#F5F5F5;
}
#donation_list{
max-width: 360px;
margin-left: auto;
margin-right: auto;
}
.donation_list ul li{
padding: 15px 0px;
color: #777777;
font-size: 16px;
line-height: 1.7;
border-bottom: dashed #f1f1f1 1px;
overflow: hidden;
}
.donation_list ul li .date,
.donation_list ul li .name,
.donation_list ul li .sum{
float: left;
overflow: hidden;
text-overflow:ellipsis;
white-space: nowrap;
}
.donation_list ul li .date{
width: 100px;
}
.donation_list ul li .sum{
width: 110px;
text-align: right;
}
.donation_list ul li .name{
width: -moz-calc(100% - 210px);
width: -webkit-calc(100% - 210px);
width: calc(100% - 210px);
text-align: center;
}
</style>
Html如下所示:
HTML代码
<script src="js/jquery-1.11.1.min.js"></script>
Js如下所示:
scrollUpDown($('#donation_list'));
        function scrollUpDown(obj) {
            var _height = obj.outerHeight();
            var _html = obj.find('#donation_list ul').html();
            obj.find('#donation_list ul').html(_html);
            function scroll() {
                return setInterval(function() {
                    if (parseFloat(obj.css('margin-top')) > -(_height)) {
                        obj.css({ 'margin-top': parseFloat(obj.css('margin-top')) - 1 });
                    } else {
                        obj.css({ 'margin-top': 0 });
                    }
                }, 60);
            }
            var _interval = scroll();
            obj.hover(function() {
                _interval = clearInterval(_interval);
            }, function() {
                _interval = scroll();
            });
        }
 
如果是要能切换的无缝对接,就如下所示:
