html结构

<div class="process_list-lpu">

                <div class="process_line"></div>

                <div class="content_list">

                    <ul>

                        <li><a href="javascipt:;">End customer get product<b>1</b></a> </li>

                        <li><a href="javascipt:;">Log in EFOSE website and present installation or maintenance requirements <b>2</b></a></li>

                        <li><a href="javascipt:;">EFOSE prefer contact service point<b>3</b></a> </li>

                        <li style="margin-left:115px;"><a href="javascipt:;">Customer contact service point to get service<b>4</b></a> </li>

                        <li><a href="javascipt:;">Customer pays the bill directly or EFOSE pays the maintenance cost<b>5</b></a> </li>

                    </ul>

                    <div class="clear"></div>

                </div>



            </div>

主要的css样式

.line-lpu{ height:55px; position:relative; width:100%; overflow:hidden;}

    .line-lpu span{ width:43px; height:46px; background:url('https://www.efose.com/images/banners/lpu_03.png') no-repeat; position:absolute;top:0;}

    .border-lpu{border-bottom:1px solid #959595; height:23px; }

     .join-lpu li{ width:19%; float:left; margin-right:8px;background:none; padding:0; }

    .join-lpu li a{ display:block; color:#606060; text-decoration:none; border:1px solid #959595; min-height:215px; padding:10px;position:relative; overflow:hidden;}

    .join-lpu li a:hover{border:1px solid #337ab7;}

    .join-lpu li b{ font-size:60px; position:absolute; bottom:7px; right:-1px; font-style:italic; color:#c7c7c7;}

    .clear{clear:both;}

    .step-lpu span{ background:url('https://www.efose.com/images/banners/icon-lpu.png') no-repeat; display:block; width:75px; height:65px; margin-left:28px;}

    .step-lpu .icon0{ background-position:0 0;}

    .step-lpu .icon1{ background-position:0 -70px;}

    .step-lpu .icon2{ background-position:0 -140px;}

    .step-lpu .icon3{ background-position:0 -204px; height:58px; margin-bottom:7px;}

    .step-lpu .icon4{ background-position:0 -260px;}

4，JavaScript的编写

<script type="text/javascript">

        //实例化animationHover对象

        window.onload = function(){

            var ah = new animationHover();

            ah.init();

        };

        //初始化标签对象

        function animationHover(){

            this.step = document.getElementById('step');

            this.stepLi = this.step.getElementsByTagName('li');

            this.line = document.getElementById('line');

            this.attr = null;

            this.timer = null;

            this.target = null;



            }

        //初始化事件

        animationHover.prototype.init=function(){

            This =this;

            for(var i=0;i<this.stepLi.length;i++){

                this.stepLi[i].index=i;

                //给li标签绑定事件

                this.stepLi[i].onmouseover=function(e){

                    var myIndex=this.index;

                    This.onOver(This.line,(myIndex*162+55));

                    };

                this.stepLi[i].onmouseout=function(){

                   This.line.style.left=myIndex*162+55+'px';

                    };



                }

            };

        //定义鼠标经过的处理函数

        animationHover.prototype.onOver=function(obj,target){

            This=this;

            clearInterval(this.timer);

            This.target=target;

            timer=setInterval(function(){

                var target=This.target; //停止的目标点

                var attrValue=parseInt(This.getStyle(obj,'left'));

                var dx=target-attrValue; //距目标点的"路程"

                var speed=1/10*dx;

                speed=speed>0?Math.ceil(speed):Math.floor(speed);

                            //防止取整引起的抖动

                if(target==attrValue) clearInterval(timer);

                            //如果到达目标点，关闭定时器

                else{

                    obj.style.left=attrValue+speed+'px';

                }

                },100);



            };

        //获取当前标签对象的css属性值

        animationHover.prototype.getStyle =function(obj,attr){

            if(obj.currentStyle){

                return obj.currentStyle[attr];

            }else{

                return getComputedStyle(obj,false)[attr];

            }

            };

</script>
