[导读] 本文章主要汇集了和种marquee和js(javascript)图片无缝滚动方法，有需要用的同学可尝试参考参考。...

下面是我在网上找的一个比较简单的marquee和js相结合解决图片无缝滚动的方法，包括向上、下、左、右四个方向滚动，下面给大家介绍一下；
先了解一下实例代码中用到的对象的几个的属性：
1、innerHTML:设置或获取位于对象起始和结束标签内的 HTML
2、scrollHeight: 获取对象的滚动高度。
3、scrollLeft:设置或获取位于对象左边界和窗口中目前可见内容的最左端之间的距离
4、scrollTop:设置或获取位于对象最顶端和窗口中可见内容的最顶端之间的距离
5、scrollWidth:获取对象的滚动宽度
6、offsetHeight:获取对象相对于版面或由父坐标 offsetParent 属性指定的父坐标的高度
7、offsetLeft:获取对象相对于版面或由 offsetParent 属性指定的父坐标的计算左侧位置
8、offsetTop:获取对象相对于版面或由 offsetTop 属性指定的父坐标的计算顶端位置
9、offsetWidth:获取对象相对于版面或由父坐标 offsetParent 属性指定的父坐标的宽度
第一种：图片像上无缝滚动

<style type="text/css">
<!--样式代码
#demo {
background: #FFF;
overflow:hidden;
border: 1px dashed #CCC;
height: 100px;
text-align: center;
float: left;
}
#demo img {
border: 3px solid #F2F2F2;
display: block;
}
-->
</style>
向上滚动
<div id="demo">
<div id="demo1">
<div id="imagest">
<div id="images"><a href=""><img src="wp-content/themes/Hcms/images/siyuan-logof.jpg" width="166" height="67" alt="" /></a></div>

</div>
<div id="demo2"></div>
</div>
<script>
<!--
var speed=10; //数字越大速度越慢
var tab=document.getElementById("demo");
var tab1=document.getElementById("demo1");
var tab2=document.getElementById("demo2");
tab2.innerHTML=tab1.innerHTML; //克隆demo1为demo2
function Marquee(){
if(tab2.offsetTop-tab.scrollTop<=0)//当滚动至demo1与demo2交界时
tab.scrollTop-=tab1.offsetHeight //demo跳到最顶端
else{
tab.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed);
tab.onmouseover=function() {clearInterval(MyMar)};//鼠标移上时清除定时器达到滚动停止的目的
tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};//鼠标移开时重设定时器
-->
</script><!--向上滚动结束--> |
第二种：图片向下无缝滚动

var tab=document.getElementById("demo");
var tab1=document.getElementById("demo1");
var tab2=document.getElementById("demo2");
tab2.innerHTML=tab1.innerHTML; //克隆demo1为demo2
tab.scrollTop=tab.scrollHeight
function Marquee(){
if(tab1.offsetTop-tab.scrollTop>=0)//当滚动至demo1与demo2交界时
tab.scrollTop+=tab2.offsetHeight //demo跳到最顶端

var MyMar=setInterval(Marquee,speed);

</script><!--图片向下滚动结--> |
第三种：图片向左无缝滚动
| 代码如下 |
复制代码 |
<style type="text/css">

</div>
<div id="demo2"></div>
</div>
</div>
<script>
<!--
var speed=10; //数字越大速度越慢
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.offsetWidth
else{
tab.scrollLeft++;
}
}
var MyMar=setInterval(Marquee,speed);
tab.onmouseover=function() {clearInterval(MyMar)};
tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};
-->
</script><!--图片向左无缝滚动结束--> |
第四种：图片向右无缝滚动
| 代码如下 |
复制代码 |
<style type="text/css">

#indemo {
float: left;
width: 800%;
}
#demo1 {
float: left;
}
#demo2 {
float: left;
}
-->
</style>
|
向右滚动
| 代码如下 |
复制代码 |
<div id="demo">
<div id="indemo">
<div id="demo1">
<div id="imagest">
<div id="images"><a href=""><img src="wp-content/themes/Hcms/images/siyuan-logof.jpg" width="166" height="67" alt="" /></a></div>

</div>
<div id="imagest">
<div id="images"><a href=""><img src="wp-content/themes/Hcms/images/siyuan-logof.jpg" width="166" height="67" alt="" /></a></div>

<div id="imgtit"><a href=""title=""></a></div>
</div>
<div id="imagest">
<div id="images"><a href=""><img src="wp-content/themes/Hcms/images/siyuan-logof.jpg" width="166" height="67" alt="" /></a></div>
<div id="imgtit"><a href=""title=""></a></div>
</div>
</div>
<div id="demo2"></div>
</div>
</div>
<script>
<!--
var speed=10; //数字越大速度越慢
var tab=document.getElementById("demo");
var tab1=document.getElementById("demo1");
var tab2=document.getElementById("demo2");
tab2.innerHTML=tab1.innerHTML;
function Marquee(){
if(tab.scrollLeft<=0)
tab.scrollLeft+=tab2.offsetWidth
else{
tab.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed);
tab.onmouseover=function() {clearInterval(MyMar)};
tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};
-->
</script> |
以上就是介绍的marquee结合js来使图片向上下左右四个方向无缝滚动的方法，当然了，网上还有其他方法，个人觉得这个方法比较简单，代码又不冗余，大家可以试下。 |
