<style type="text/css">
#demo {overflow:scroll;width:740px; } 
#indemo { float: left; width: 800%;}
#demo1 { float: left; }
#demo2 { float: left;margin-left:7px;}
</style>
<script src="bootstrap-3.3.5-dist/js/jquery-1.11.3.js"></script>
<div id="demo">
 <div id="indemo">
 <div id="demo1">
  <a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
  <a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
  <a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
 </div>
 <div id="demo2"></div> </div>
</div>
一 采用jquery方式实现文字横移
<script>
 var speed=20;
 $("#demo2").html($("#demo1").children().clone());
 var n=0;
 function Marquee(){
 if(n>=$("#demo").innerWidth())
  n=0;
 else{
  n++;
 }
 $("#demo").scrollLeft( n );
 }
var MyMar=setInterval(Marquee,speed);
 $("#demo").mouseover(function(){clearInterval(MyMar)});
 $("#demo").mouseout(function(){MyMar=setInterval(Marquee,speed)});
</script>
二 采用原生script实现横移
<script>
var speed=10;
var tab=document.getElementById("demo");
var tab1=document.getElementById("demo1");
var tab2=document.getElementById("demo2");
$("#demo2").text($("#demo1").clone());
$("#demo2").clone();
function Marquee(){
 if(tab2.offsetWidth-tab.scrollLeft<=0)
 tab.scrollLeft-=tab1.offsetWidth
 else{
 tab.scrollLeft++;
 }
}
var MyMar=setInterval(Marquee,speed);
tab.onmouseover=function() {clearInterval(MyMar)};
tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};
</script>
