Copy code The code is as follows:

<script> <br>var speed=20;/*speed The larger the value, the slower the speed*/ <br>document.getElementById('www_qpsh_com2').innerHTML=document.getElementById('www_qpsh_com1').innerHTML; <br><br>/*The two layers alternate back and forth*/ <br>function Marquee(){ <br>if(document.getElementById('www_qpsh_com2').offsetWidth-document.getElementById('www_qpsh_com').scrollLeft<=0) <BR>document.getElementById('www_qpsh_com').scrollLeft -=document.getElementById('www_qpsh_com1').offsetWidth; <BR>else{ <BR>document.getElementById('www_qpsh_com').scrollLeft ; <BR>} <BR>document.getElementById('my_marquee_info').innerHTML= ''; <BR>document.getElementById('my_marquee_info').innerHTML ='div.scrollTop:' document.getElementById('www_qpsh_com').scrollLeft; <BR>} <BR>var MyMar=setInterval(Marquee,speed) ; <BR>www_qpsh_com.onmouseover=function() {clearInterval(MyMar);} <BR>www_qpsh_com.onmouseout=function() {MyMar=setInterval(Marquee,speed);} <BR></script>

Demo code:

[Ctrl A select all Note: If you need to introduce external Js, you need to refresh to execute
]<script> var speed=20;/*速度数值越大速度越慢*/ document.getElementById('www_qpsh_com2').innerHTML=document.getElementById('www_qpsh_com1').innerHTML; function Marquee(){ if(document.getElementById('www_qpsh_com2').offsetWidth-document.getElementById('www_qpsh_com').scrollLeft<=0) document.getElementById('www_qpsh_com').scrollLeft-=document.getElementById('www_qpsh_com1').offsetWidth; else{ document.getElementById('www_qpsh_com').scrollLeft++; } document.getElementById('my_marquee_info').innerHTML=''; document.getElementById('my_marquee_info').innerHTML+='div.scrollTop:'+document.getElementById('www_qpsh_com').scrollLeft; } var MyMar=setInterval(Marquee,speed); www_qpsh_com.onmouseover=function() {clearInterval(MyMar);} www_qpsh_com.onmouseout=function() {MyMar=setInterval(Marquee,speed);} </script>
