通过jquery的animate实现上下单行自动跳转
<script type="text/javascript" src="__ROOT__/Style/H/js/jquery-1.7.2.min.js"></script>
<style>
.rool-div{
height:50px;
width:700px;
margin:0 auto;
position: relative;
overflow: hidden;
border:2px solid red;
}
.roll{
height:50px;
width:700px;
margin:0 auto;
}
.roll span{
display:block;
height:50px;
width:700px;
line-height:50px;
}
a {
text-decoration:none;
display:inline-block;
}
</style>
<div class="rool-div">
<div class="roll" id="roll">
<span><a href="#">1. Lorem Ipsum is simply dummy text of the printing and typesetting industry</a></span>
<span><a href="#">2. It is a long established fact that a reader will be distracted</a></span>
<span><a href="#">3. Many desktop publishing packages</a></span>
<span><a href="#">4. All the Lorem Ipsum generators on the Internet tend to repeat predefined</a></span>
<span><a href="#">5. The standard chunk of Lorem Ipsum used</a></span>
<span><a href="#">6. English versions from the 1914 translation by H. Rackham.</a></span>
<span><a href="#">7. Bu metin deneme amaçl?d?r the standard chunk of Lorem Ipsum used</a></span>
</div>
</div>
<script>
(function($){
$.fn.extend({
Roll:function(){
return this.each(function(){
var n=0;
$('#roll span a').hover(function(){
$(this).css('color','red');
},function(){
$(this).css('color','green');
});
var timername=setInterval(function(){Play()},1000);
$("#roll").hover(
function()
{
clearInterval(timername);
},
function()
{
timername=setInterval(function(){Play()},1000);
});
function Play(){
if($("#roll>span").length>n)
n++;
else
n=1;
$("#roll").animate({'marginTop':-($("#roll span" ).height())*(n-1)});
}
});
}
})
})(jQuery);
</script>
二 通过scrollLeft函数实现自动左右移动（谷歌浏览器偶尔不能移动）
<style type="text/css">
#demo {overflow:hidden;width:740px; }
#indemo { float: left; width: 800%;}
#demo1 { float: left; }
#demo2 { float: left;margin-left:7px;}
</style>
<script src="bootstrap-3.3.5-dist/js/jquery-1.11.3.js"></script>
<div id="demo">
<div id="indemo">
<div id="demo1">
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
<a href="#"><img src="zhuanpan/images/pointer.png" alt="#" /></a>
</div>
<div id="demo2"></div>
</div>
</div>
<script>
var speed=10;
var tab=document.getElementById("demo");
var tab1=document.getElementById("demo1");
var tab2=document.getElementById("demo2");
$("#demo2").text($("#demo1").clone());
$("#demo2").clone();
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>
