最近做一个单页,需要使用到js实现左右产品滚动效果,发现很多代码在一起会发生冲突。最终找到一个上下左右可以在一个页面任意滚动的代码。这里记录下来,需要的朋友可以直接使用了:
1、产品图片向上无缝滚动代码:
- <!–向上滚动代码开始–>
- <div id=“colee” style=“overflow:hidden;height:253px;width:410px;”>
- <div id=“colee1”>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- <p><img src=“”></p>
- </div>
- <div id=“colee2”></div>
- </div>
- <script>
- var speed=30;
- var colee2=document.getElementById(“colee2”);
- var colee1=document.getElementById(“colee1”);
- var colee=document.getElementById(“colee”);
- colee2.innerHTML=colee1.innerHTML; //克隆colee1为colee2
- function Marquee1(){
- //当滚动至colee1与colee2交界时
- if(colee2.offsetTop-colee.scrollTop<=0){
- colee.scrollTop-=colee1.offsetHeight; //colee跳到最顶端
- }else{
- colee.scrollTop++
- }
- }
- var MyMar1=setInterval(Marquee1,speed)//设置定时器
- //鼠标移上时清除定时器达到滚动停止的目的
- colee.onmouseover=function() {clearInterval(MyMar1)}
- //鼠标移开时重设定时器
- colee.onmouseout=function(){MyMar1=setInterval(Marquee1,speed)}
- </script>
- <!–向上滚动代码结束–>
2、产品向下无缝滚动代码:
- <!–下面是向下滚动代码–>
- <div id=“colee_bottom” style=“overflow:hidden;height:253px;width:410px;”>
- <div id=“colee_bottom1”>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- <p><img src=“/jscss/demoimg/200907/bg3.jpg”></p>
- </div>
- <div id=“colee_bottom2”></div>
- </div>
- <script>
- var speed=30
- var colee_bottom2=document.getElementById(“colee_bottom2”);
- var colee_bottom1=document.getElementById(“colee_bottom1”);
- var colee_bottom=document.getElementById(“colee_bottom”);
- colee_bottom2.innerHTML=colee_bottom1.innerHTML
- colee_bottom.scrollTop=colee_bottom.scrollHeight
- function Marquee2(){
- if(colee_bottom1.offsetTop-colee_bottom.scrollTop>=0)
- colee_bottom.scrollTop+=colee_bottom2.offsetHeight
- else{
- colee_bottom.scrollTop–
- }
- }
- var MyMar2=setInterval(Marquee2,speed)
- colee_bottom.onmouseover=function() {clearInterval(MyMar2)}
- colee_bottom.onmouseout=function() {MyMar2=setInterval(Marquee2,speed)}
- </script>
- <!–向下滚动代码结束–>
3、向左无缝滚动代码:
- <!–下面是向左滚动代码–>
- <div id=“colee_left” style=“overflow:hidden;width:500px;”>
- <table cellpadding=“0” cellspacing=“0” border=“0”>
- <tr><td id=“colee_left1” valign=“top” align=“center”>
- <table cellpadding=“2” cellspacing=“0” border=“0”>
- <tr align=“center”>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- </tr>
- </table>
- </td>
- <td id=“colee_left2” valign=“top”></td>
- </tr>
- </table>
- </div>
- <script>
- //使用div时,请保证colee_left2与colee_left1是在同一行上.
- var speed=30//速度数值越大速度越慢
- var colee_left2=document.getElementById(“colee_left2”);
- var colee_left1=document.getElementById(“colee_left1”);
- var colee_left=document.getElementById(“colee_left”);
- colee_left2.innerHTML=colee_left1.innerHTML
- function Marquee3(){
- if(colee_left2.offsetWidth-colee_left.scrollLeft<=0)//offsetWidth 是对象的可见宽度
- colee_left.scrollLeft-=colee_left1.offsetWidth//scrollWidth 是对象的实际内容的宽,不包边线宽度
- else{
- colee_left.scrollLeft++
- }
- }
- var MyMar3=setInterval(Marquee3,speed)
- colee_left.onmouseover=function() {clearInterval(MyMar3)}
- colee_left.onmouseout=function() {MyMar3=setInterval(Marquee3,speed)}
- </script>
- <!–向左滚动代码结束–>
4、向右无缝滚动代码:
- <!–下面是向右滚动代码–>
- <div id=“colee_right” style=“overflow:hidden;width:500px;”>
- <table cellpadding=“0” cellspacing=“0” border=“0”>
- <tr><td id=“colee_right1” valign=“top” align=“center”>
- <table cellpadding=“2” cellspacing=“0” border=“0”>
- <tr align=“center”>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- <td><p><img src=“/jscss/demoimg/200907/bg3.jpg”></p></td>
- </tr>
- </table>
- </td>
- <td id=“colee_right2” valign=“top”></td>
- </tr>
- </table>
- </div>
- <script>
- var speed=30//速度数值越大速度越慢
- var colee_right2=document.getElementById(“colee_right2”);
- var colee_right1=document.getElementById(“colee_right1”);
- var colee_right=document.getElementById(“colee_right”);
- colee_right2.innerHTML=colee_right1.innerHTML
- function Marquee4(){
- if(colee_right.scrollLeft<=0)
- colee_right.scrollLeft+=colee_right2.offsetWidth
- else{
- colee_right.scrollLeft–
- }
- }
- var MyMar4=setInterval(Marquee4,speed)
- colee_right.onmouseover=function() {clearInterval(MyMar4)}
- colee_right.onmouseout=function() {MyMar4=setInterval(Marquee4,speed)}
- </script>
- <!–向右滚动代码结束–>
