完整的html+css+javascript实现跟随鼠标移动显示选中效果

1，显示效果：

2,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>

3，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:;}
    .border-lpu{border-bottom:1px  solid #959595; height:23px; }
     .join-lpu li{ width:19%; float:left; margin-right:8px;background:none; padding:; }
    .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>
