jQuery文字横向滚动效果的实现代码

<div id="s" style="width:100px; position:relative; white-space:nowrap; overflow:hidden; height:20px;"> <div id="noticeList" style="position:absolute; top:0; height:20px;"><span>jQuery文字横向滚动</span><span>jQuery制作文字横向滚动</span><span>www.VeVB.COm</span></div> </div>

$.fn.textScroll=function(){ var speed=60,flag=null,tt,that=$(this),child=that.children(); var p_w=that.width(), w=child.width(); child.css({left:p_w}); var t=(w+p_w)/speed * 1000; function play(m){ var tm= m==undefined ? t : m; child.animate({left:-w},tm,"linear",function(){ $(this).css("left",p_w); play(); }); } child.on({ mouseenter:function(){ var l=$(this).position().left; $(this).stop(); tt=(-(-w-l)/speed)*1000; }, mouseleave:function(){ play(tt); tt=undefined; } }); play(); }

$.fn.textScroll=functioon(){ var p = $(this), c = p.children(), speed=3000;// 值越大，速度越小 var cw = c.width(),pw=p.width(); var t = (cw / 100) * speed; var f = null, t1 = 0; function ani(tm) { counttime(); c.animate({ left: -cw }, tm, "linear", function () { c.css({ left: pw }); clearInterval(f); t1 = 0; t=((cw+pw)/100)*speed; ani(t); }); } function counttime() { f = setInterval(function () { t1 += 10; }, 10); } p.on({ mouseenter: function () { c.stop(false, false); clearInterval(f); console.log(t1); }, mouseleave: function () { ani(t - t1); console.log(t1); } }); ani(t); }
