1.先看效果演示:2.原生纯js代码如下:var speed=10; //数字越大文字滚动速度越慢var tab=document.getElementById(“demo”);var tab1=document.getElementById(“demo1”);var tab2=document.getElementById(“demo2”);tab2.innerHTML=tab1.innerHTML;function Marquee(){if(tab2.offsetWidth-tab.scrollLeft<=0)tab.scrollLeft-=tab1.offsetWidthelse{tab.scrollLeft++;}}var MyMar=setInterval(Marquee,speed);tab.onmouseover=function() {clearInterval(MyMar)};tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};var onOff = true;var Time = setInterval(Chang,3000);function Chang(){if(onOff){oFig.style.marginLeft=’-100%’;onOff = false;}else{oFig.style.marginLeft=’0′;onOff = true;}}
