列表无缝滚动和列表可切换的无缝滚动，如下图:
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_listulli{
padding:15px0px;
color:#777777;
font-size:16px;
line-height:1.7;
border-bottom:dashed#f1f1f11px;
overflow:hidden;
}
.donation_listulli.date,
.donation_listulli.name,
.donation_listulli.sum{
float:left;
overflow:hidden;
text-overflow:ellipsis;
white-space:nowrap;
}
.donation_listulli.date{
width:100px;
}
.donation_listulli.sum{
width:110px;
text-align:right;
}
.donation_listulli.name{
width:-moz-calc(100%-210px);
width:-webkit-calc(100%-210px);
width:calc(100%-210px);
text-align:center;
}
</style>
Html如下所示:
<scriptsrc="js/jquery-1.11.1.min.js"></script>
Js如下所示:
scrollUpDown($('#donation_list'));
functionscrollUpDown(obj){
var_height=obj.outerHeight();
var_html=obj.find('#donation_listul').html();
obj.find('#donation_listul').html(_html);
functionscroll(){
returnsetInterval(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：
Css如下所示：
<style>
*{
margin:0;

}
li{
list-style:none;
}
.list-wrap{
