JS实现图片无间断滚动代码汇总

前端技术 2023/09/07 JavaScript

本文整理汇总了JavaScript实现图片滚动的常见代码，可以实现向上下左右四个方向的无缝滚动的效果，这是前端设计开发时常用的一个图片特效，你可只用其中的一种滚动效果。

具体的实例代码如下：

<script type=\"text/javascript\">
// 自动滚动
function boxmove(d1,d2,d3,e,obj){
 var speed=30;
 var demo=document.getElementById(d1);
 var demo1=document.getElementById(d2);
 var demo2=document.getElementById(d3);
 demo2.innerHTML=demo1.innerHTML;
 function boxTop(){
   if(demo2.offsetTop-demo.scrollTop<=0){demo.scrollTop-=demo1.offsetHeight}
   else{demo.scrollTop++}
  }
 function boxRight(){
   if(demo.scrollLeft<=0){demo.scrollLeft+=demo2.offsetWidth}
   else{demo.scrollLeft--}
  }
 function boxBottom(){
   if(demo1.offsetTop-demo.scrollTop>=0){demo.scrollTop+=demo2.offsetHeight}
   else{demo.scrollTop--}
  }
 function boxLeft(){
   if(demo2.offsetWidth-demo.scrollLeft<=0){demo.scrollLeft-=demo1.offsetWidth}
   else{demo.scrollLeft++}
  }
 if(e==1){
   var MoveTop=setInterval(boxTop,speed);
   demo.onmouseover=function(){clearInterval(MoveTop);}
   demo.onmouseout=function(){MoveTop=setInterval(boxTop,speed)}
  }
 if(e==2){
   var MoveRight=setInterval(boxRight,speed);
   demo.onmouseover=function(){clearInterval(MoveRight)}
   demo.onmouseout=function(){MoveRight=setInterval(boxRight,speed)}
  }
 if(e==3){
   var MoveBottom=setInterval(boxBottom,speed);
   demo.onmouseover=function(){clearInterval(MoveBottom);}
   demo.onmouseout=function(){MoveBottom=setInterval(boxBottom,speed)}
  }
 if(e==4){
   var MoveLeft=setInterval(boxLeft,speed)
   demo.onmouseover=function(){clearInterval(MoveLeft)}
   demo.onmouseout=function(){MoveLeft=setInterval(boxLeft,speed)}
  }
 if(e==\"top\"){
   MoveTop=setInterval(boxTop,speed)
   obj.onmouseout=function(){clearInterval(MoveTop);}
  }
 if(e==\"right\"){
   MoveRight=setInterval(boxRight,speed)
   obj.onmouseout=function(){clearInterval(MoveRight);}
  }
 if(e==\"bottom\"){
   MoveBottom=setInterval(boxBottom,speed)
   obj.onmouseout=function(){clearInterval(MoveBottom);}
  }
 if(e==\"left\"){
   MoveLeft=setInterval(boxLeft,speed)
   obj.onmouseout=function(){clearInterval(MoveLeft);}
  }
 }
