原文复制三边，用animate跑，每次跑1/3，然后用css(‘left’,reset) 移动位置，其他就不多解释了。
var scroller = $(‘#rtext’),html = scroller.html(),scrollInterval = -1,scrollTime = 30000,reset = 0;
scroller.html( html + html + html);
scrollInterval = window.setInterval(function(){
scroll(true);
},scrollTime/4);function scroll(){
scroller.css({‘left’:reset}).stop().animate({‘left’:"-="+scroller.width()/3},scrollTime/3,’linear’);
}scroller.css(‘width’,'auto’).hover(function(){
$(‘#rtext’).stop();
scrollInterval = window.clearInterval(scrollInterval);
},function(){
scrollInterval = window.clearInterval(scrollInterval);
scrollInterval = window.setInterval(function(){
scroll();
},scrollTime/3);
scroller.stop().animate({‘left’:"-="+scroller.width()/3},scrollTime/3,’linear’);
if(parseInt(scroller.css(‘left’)) < – scroller.width()/3){
reset = parseInt(scroller.css(‘left’)) + scroller.width()/3;
}else{
reset = parseInt(scroller.css(‘left’));
}
});
scroll();
