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 amaçlıdır 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>
