//获取每一个li
var list=my$('ull').children;
console.log(list);
//获取到筋斗云图片
var im=my$('cloud');
//获取图片的宽度
var imgWidth=im.offsetWidth;
console.log(imgWidth);
for(var i=0;i<list.length;i++){
//设置index值用来储存移动的距离
list[i].setAttribute('index',i);
//遍历所有li，每个li绑定三个时间指向同一个函数f1
list[i].onmouseover=f1;
list[i].onmouseout=f1;
list[i].onclick=f1;
//实现函数f1
function f1(e){
switch(e.type) {
case 'mouseover':
//获取当前li的index值
index=this.getAttribute('index');
//调用变速移动函数
movecs(im,imgWidth*index);
break;
case 'click':
index=this.getAttribute('index');
//点击之后固定
im.style.left=imgWidth*index+'px';
//点击了其中一个li之后的操作，移开鼠标之后不会弹回去
this.onmouseout=false;
for(var k=0;k<list.length;k++){
list[k].setAttribute('jndex',k);
list[k].onmouseover=function(){

最终效果如下：云彩跟随鼠标移动，点击固定
